Table chart options

Stay organized with collections Save and categorize content based on your preferences.

Table charts provide direct views of your data. They can be formatted to illustrate elements of the data that you'd like to highlight.

Building a table chart

Table charts accept dimensions, measures, pivots, subtotals, table calculations, custom fields, and row or column totals. Table charts support up to 5,000 rows and up to 200 pivoted columns.

To use a table chart, run your query and click the table icon on the Visualization bar.

To edit your table visualization, click the gear in the upper right corner of the Visualization bar.

Options listed below may be grayed out or hidden when incompatible with the composition of your table or if they conflict with other settings you have chosen.

Data bar options

Several options on the Data bar can affect both your visualization and the data table.

Subtotals

The option to add subtotals to your table visualization appears on the Data bar when your data table contains at least two dimensions. Select the Subtotals checkbox and press Run. Subtotals appear only in the table visualization. They do not appear in the data table.

Subtotals are calculated for all dimensions other than the rightmost dimension. To change the dimensions that are subtotaled, reorder the positions of the dimensions in your data table.

There are some things to keep in mind about how subtotals work:

  • Subtotals that count unique items might not add up as you expect if the same item appears in several categories. In those cases, Looker counts each item once rather than counting every duplicate appearance. Looker calculates column totals in the same way.
  • Subtotals of table calculations that perform aggregations, such as calculations using percentile or mean, might not add up as you expect. This is because table calculations calculate subtotals using the other subtotal values, not using the values in the data column. For example, if you have two User Count subtotals of 30,500 and 24,312 and you have a table calculation such as mean(${users.count}), the table calculation will return 27,406 for both subtotal rows because it is performing the calculation (30500 + 24312)/2.
  • Subtotals are not available when you filter on a measure.
  • If your data table row limit cuts off your data table partway through a subtotal category, the entire category will be hidden from the table visualization.
  • Sorting occurs within each subtotal category independently.
  • The leftmost subtotal is always sorted. When you sort by multiple columns, subtotal columns are given precedence.

Subtotals can be collapsed or expanded in the table visualization. See the Collapse Subtotal section for more information.

Dialect support for subtotals

The ability to use subtotals depends on the database dialect your Looker connection is using. In the latest release of Looker, the following dialects support subtotals:

There are some things to keep in mind about dialect support for subtotals:

  • When you use MySQL, all subtotals must sort ascending.
  • Pivots in MySQL and Snowflake will fail if you are using subtotals and the underlying result set contains more than 30,000 rows (regardless of any row limits you set in the data table).
  • Using subtotals with BigQuery and Redshift may decrease query speeds compared to queries without subtotals.

Row Totals

If your chart contains pivots, you can add row totals to your chart by checking the Row Totals checkbox in the Data bar. See the Exploring data in Looker documentation page for more information.

The arrow to the right of the Row Totals checkbox lets you toggle the placement of the totals column between the far right default placement and a placement further to the left, after dimensions and dimension table calculations.

Totals

You can add column totals for measures and table calculations by selecting Totals in the Data bar. See the Exploring data in Looker documentation page for more information.

Column Limit

If your data table contains pivots, you can add a column limit to your chart by entering any number between 1 and 200 in the Column Limit box. Dimensions, dimension table calculations, row total columns, and measure table calculations outside of pivots are not counted toward the column limit. Pivoted groups each count as one column toward the column limit. See the Filtering and limiting data documentation page for more information.

Row Limit

You can add a row limit to your chart by entering any number between 1 and 5,000 into the Row Limit box on the Data tab. If your query exceeds the row limit you have set, you cannot sort row total or table calculation columns.

When you add a table chart to a dashboard, if the Row Limit is left blank, the dashboard imposes a limit of 1,000 rows to the table chart tile. To increase the row limit on a dashboard tile, enter a higher row limit up to 5,000, which is the maximum number of rows that can be presented.

Calculations

If you have the appropriate permissions, you can add table calculations to your chart by clicking the Add calculation button on the Data tab. See the Using table calculations documentation page for more information.

You can also use the Custom Fields section of the field picker.

Column menu options

When column menu options are accessed through a dashboard tile in view mode, changes to settings are not saved. To save changes to settings, enter edit mode on the dashboard, click Edit in the tile's three-dot menu, and change the settings in the edit window that appears.

Table charts have a three-dot icon at the upper right of each column, which appears when you hover over the column header:

Clicking the three-dot icon reveals a column menu that provides options for freezing, copying, and resizing table columns as you view them:

Freeze

Clicking the Freeze option freezes a table column to the left side of the chart. The frozen column remains visible on the left side during horizontal scrolling. Multiple columns can be frozen.

To unfreeze a column, click the three-dot icon again and select Unfreeze.

Copy Values

Clicking Copy Values copies the column header and all the values in the column, which can then be pasted into a spreadsheet, text file, or Looker filter. You can also click on a cell or a range of cells within the visualization and copy the contents using the keyboard shortcuts Command-C (Mac) or Ctrl+C (Windows).

Autosize All Columns

Clicking Autosize All Columns sizes the width of each column to fit its column heading name or its longest data value, whichever is wider.

Reset All Column Widths

Clicking Reset All Column Widths resizes each column to its default width, which is the width that is set when Size Columns to Fit is turned on, or the width that is set by Autosize All Columns if sizing columns to fit makes columns too narrow.

Sorting columns

The default sort order is explained on the Exploring data in Looker documentation page.

You can sort columns in the table visualization by clicking on column headers within the visualization. Each time you click a header, its column switches between ascending and descending sort order. A chevron appears in the column header to indicate that the chart is sorted by that column. The chevron points up to indicate an ascending sort and down to indicate a descending sort.

You can sort by multiple columns by holding down the Shift key and then clicking on the column headers in the order you would like them sorted.

If subtotals are enabled, the leftmost subtotal is always sorted. Sorting occurs within each subtotal category independently.

If you reach a row limit, you will not be able to sort row totals or table calculations.

Manually moving and pinning columns

When columns are rearranged through a dashboard tile in view mode, changes to the column order are not saved. To save changes to column order, enter edit mode on the dashboard, click Edit in the tile's three-dot menu, and move the columns in the edit window that appears.

Clicking and dragging column headers in the table visualization lets you move any column, including pivot groups and individual pivot columns, to any other location in the visualization. The order of the columns within the Data table will not change.

While you are clicking and dragging a column, if you approach the left edge of the visualization, a pin icon appears:

If you drop the column while the pin icon is present, the column will be pinned to the side of your visualization. The pinned column remains visible on the side during horizontal scrolling. Multiple columns can be pinned.

If you drag a column outside of the bounds of the visualization, an icon of a crossed-out eye appears:

If you drop the column while the eye icon is present, the column will not move from its original position.

When you download a table with columns that have been rearranged, the columns will appear in their original order (the order in which they appear in the data table) even if the With visualization options applied setting is selected.

Manually resizing columns

To manually resize columns, click the right border of the column header and drag it left or right.

Manually resizing columns overrides Size Columns to Fit.

Plot menu options

Table Theme

You can choose table coloring options:

  • Classic: The table appears as it does in the Data section, with blue dimensions, orange measures, and green table calculations.
  • White: The table header is white, the data rows alternate between white and gray, and the text is black.
  • Gray: The table header is gray, the data rows alternate between white and light gray, and the text is dark gray.
  • Transparent: The table header is totally transparent, the data rows alternate between totally transparent and translucent gray, and the text adjusts itself in color. This can be useful when using a customized, embedded dashboard so that the tile background color shows through the visualization. On such a dashboard, the text color adapts to the background color, changing from black to white as needed. On the Explore page or in an embedded Look, the background is always white under the transparent visualization.
  • Unstyled: The entire table is white, the data rows are separated by gray lines, and the text is black.

Show Row Numbers

You can toggle whether to show a row number at the beginning of each table row.

Show Row Numbers is disabled when you use subtotals in your table chart.

Show Totals

Show Totals toggles whether to show column totals at the bottom of each table column.

Show Totals is disabled when Totals are not added to your report.

Show Row Totals

Show Row Totals toggles whether to show row totals at the beginning or end of each table row.

Show Row Totals is disabled when Row Totals are not added to your pivoted report.

Transpose

The Transpose option is available for visualizations that contain only one dimension. When Transpose is selected, the visualization's rows will switch to columns and the columns will switch to rows.

Limit Displayed Rows

You can show or hide rows in a visualization, based on their position in the results. For example, if your visualization displays a 7-day rolling average, you may want to hide the first 6 rows.

Click Limit Displayed Rows to enable or disable this feature. When enabled, you can specify the following options:

  • Hide or Show: Choose Hide to exclude certain rows from the visualization. Choose Show to display only a limited number of rows in the visualization.
  • First or Last: Choose if the rows to hide or show are the first or last rows in the result set.
  • Number: Specify the number of rows to hide or show.

In the Data section below your visualization, excluded rows show in a darker color and are marked with a symbol to the left of the row number:

This option is dependent on the row order. Changing the query's sort order or adding a row limit can change the rows that are shown or hidden in the visualization.

Series menu options

The series menu controls how your chart shows each data series.

In a table chart, each column is listed in the series menu for customization.

Truncate Text

When Truncate Text is turned on, the text that appears in data cells will be truncated and followed by ellipses. When it is turned off, text inside data cells wraps to subsequent lines.

To view the full version of truncated or wrapped text inside a data cell, double-click the interior of the cell; press Escape or click outside of the cell to return to the truncated or wrapped version.

The default setting for Truncate Text is on.

Truncate Column Names

When Truncate Column Names is turned on, the text that appears in column headers will be truncated. When it is turned off, text inside column headers wraps to subsequent lines.

To view the full text of a truncated or wrapped column header, hover over the column header. A tooltip will appear with the full text of the column header.

The default setting for Truncate Column Names is off.

Show Full Field Name

You can toggle whether to show the view name along with the field name for each column header. When Show Full Field Name is off, generally only the field name shows; however, measures of type count display only the view name instead.

Size Columns to Fit

Size Columns to Fit sizes the widths of all columns so that the table perfectly fits the width of the pane in which you are viewing it. When this option is toggled on, columns can still be manually re-sized, and the manually set widths will override the widths set by Size Columns to Fit. Widths set using the Size Columns to Fit option are saved when you save your visualization as a Look or add it to a dashboard.

The default setting for Size Columns to Fit is on. However, if Size Columns to Fit results in columns that are too narrow to be readable, Looker will automatically autosize all columns and will size each column based on its longest data value.

Customizations

The Customizations section lets you customize each column in the visualization.

Label

You can create a custom label for the column that will appear in the visualization.

Width

You can set the width of the column by entering a number from 1 (narrowest) through 1,000 (widest). Widths set using the Width field are saved when you save your visualization as a Look or add it to a dashboard.

Format

The Format option appears for columns that contain numeric data. Using the drop-down menu, you can choose a predefined format or create a custom format for the values in that column. If you choose Custom from the drop-down, use Excel-style formatting to create your custom format. Excel-style formatting is described on the Adding custom formatting to numeric fields documentation page.

Cell Text Layout

The formatting icons allow you to set the font color; background fill color; bold, italic, or underline font styling; and horizontal alignment for text inside the data cells for that column.

Customizing cell text layout is not available when the Cell Visualization option is set to on.

Column headers can be styled using the formatting menu.

Collapse Subtotal

The Collapse Subtotal option appears for columns that have subtotals. Enabling this option will collapse all subtotals for that column. The subtotals will remain collapsed when you save your visualization as a Look or add it to a dashboard.

You can collapse subtotals on individual cells by clicking the arrow on the left side of the cell, but those changes are not saved.

Cell Visualization

The Cell Visualization option appears for columns that contain numeric data. When this option is turned on, horizontal bar visualizations appear in the column cells, representing the value of the data in each cell. The bar length is plotted from zero (in which case no bar appears) to the maximum data value.

A color palette appears when the Cell Visualization option is enabled. The default color palette for the bar visualizations comes from the color collection selected in the Collection menu option. Clicking the palette lets you select a different palette from the collection or create a custom palette by clicking the Custom tab on the palette picker that appears. The bar colors reflect the data values from the minimum (left side of the palette) to the maximum (right side of the palette).

The Value Labels checkbox also appears when the Cell Visualization option is enabled. This checkbox toggles the appearance of value labels for each data point on a chart. The value labels appear to the right of the bar visualizations for columns with only positive values or only negative values. For columns with both positive and negative values, value labels appear to the right of the bar visualizations for negative values and to the left of the bar visualizations for positive values. Value Labels defaults to on.

If a column is pivoted by another series, bar visualizations are plotted for that column in each pivot group; and the minimum and maximum values are shared across the pivoted columns. If a series is used to pivot columns, bar visualizations are not available for that series, even if it contains numeric data.

The Cell Visualization option defaults to on for the first measure in the table visualization. For other columns with numeric data, it defaults to off.

Formatting menu options

Color collection

Choosing a color collection from the Collection drop-down menu determines the palettes available for conditional formatting rules or cell visualizations.

A color collection lets you create themed visualizations and dashboards that look good together. You can see all the palettes in each of Looker's built-in color collections on the Color collections documentation page. Your Looker admin may also create a custom color collection for your organization.

The palettes for any cell visualizations and the Palette section for each conditional formatting rule update with a palette from that collection.

Row and header formatting

Rows let you set the font size for cell text between 1 and 99 points.

Header lets you set the font size, text color, background fill color, and horizontal alignment for column headers. Header font size can range between 1 and 99 points.

Enable conditional formatting

You can apply conditional formatting to columns in a table visualization when subtotals are not present and the Cell Visualization feature is set to off for those columns. Turn on Enable Conditional Formatting to define rules that color code your table, either on a scale or by specifying values that are of interest.

This example shows a sample visualization where all values are colored on a scale, changing from red to yellow to green as the values scale from low to medium to high:

This example shows a visualization where all values over 5,000 are highlighted and made bold:

Defining formatting rules

You specify how to color code your visualization in the Rules section:

When you first enable conditional formatting, there will be one rule, set to the default of color coding on a scale.

  • To add an additional rule, click Add Rule.
  • To delete a rule, click on the trash can icon in the top right corner of that rule section.

You can apply the rule to all numeric fields in the visualization, or apply the rule to one or more fields using the Apply to box:

  • If you choose All numeric fields, the conditional formatting rule is applied to every value in all the numeric fields in the visualization. If you are color coding values on a scale, the scale will include all numeric values, even if the values in different columns are unrelated.

    If you create multiple rules using All numeric fields, the rules higher on the list have precedence over rules lower on the list. To change the precedence of a rule, click on the three horizontal bars at the top left of that rule and drag the rule higher or lower in the list.

  • If you choose Select fields, Looker displays a box that lets you select the fields where you want to apply the rule. If you enter text in the box, Looker lists only the fields that include that text.

    Select the field or fields to apply the rule. The conditional formatting will be applied only to the values in those fields.

    If you create multiple rules on the same field, only the rule highest on the list applies to the visualization and the other rules are inactive. To move a rule higher or lower on the list, click on the three horizontal bars at the top left of that rule and drag the rule higher or lower in the list.

In the Format box, choose whether to color code values along a scale or based on a logical condition:

If you format based on a logical condition, when you enter a value in the Format box, do not use thousands separators.

Color coding on a scale

If you are color coding values on a scale, click the color palette:

Choose an existing palette or create a custom palette by clicking on the Custom tab of the palette picker:

  • To add or remove colors from the scale, click the + or - buttons. You can have a maximum of 5 and a minimum of 2 colors on your scale.
  • To edit all colors of the scale, click Edit All and enter RGB hex strings, such as #2ca6cd, or CSS color names, such as mediumblue.
  • To choose a custom color for the highlighted part of your color scale, use the color wheel.

Use the following options to modify the color coding:

  • Select Reverse colors to apply the colors at the left end of the palette to values in the higher end of the data range and colors at the right end of the palette to values in the lower end of the data range.
  • Select Use X color steps to limit the number of colors used to the specified step value. When this option is not enabled, the data is colored on a gradient covering the entire palette spectrum. When this option is enabled, the data is then grouped and colored according to the number of color steps. For example, if you specify 5 color steps, the data is grouped into 5 equal buckets and the 5 colors applied, one color to each bucket of data. Valid color step numbers are from 2 to 100, inclusive.
  • Select Mirror range around center value to make equal color shifts on either side of the color palette. For example, on a scale from -100 to 0 to 100, values of -20 and a 20 will be the same color distance (10%) from the center color definition — 40% and 60% of the palette gradient respectively.
  • Use the Range fields to specify the values that determine the palette gradient start (0%), center (50%), and end (100%) colors. For the start and end colors, you can specify the minimum and maximum values in your data, specific numeric values, or percentile values. For the center value, you can specify the midpoint of the minimum and maximum data values, the data average, the data median, a specific numeric value, or a percentile value. For example, specifying start and end percentile values of 1% and 99% respectively, with a center value of 75%, causes the bottom half of the color gradient to apply to the lower 75% of your data values, and the upper half of the color gradient to apply to the top 25% of your data values.

Color coding based on a logical condition

If you are color coding values based on a logical condition (in other words, using one of the Format options beginning with If value is), choose the Background Color, Font Color, and Font Style for values that meet the condition. By default, the background color is set to the first color of the categorical palette you have chosen for your conditional formatting rule.

Include Totals

If conditional formatting is enabled, you can toggle whether totals are included in the color coding scheme.

Include Null Values as Zero

If conditional formatting is enabled, you can toggle whether null values should be represented as a zero.

Adding a table chart to dashboards

When you add a table chart to a dashboard, if the Row Limit is left blank, the dashboard imposes a limit of 1,000 rows to the table chart tile. To increase the row limit on a dashboard tile, enter a higher row limit up to 5,000, which is the maximum number of rows that can be presented.

Table charts with many rows that are added to a dashboard may look different when they are downloaded or scheduled in PDF format if the Expand tables to show all rows option is selected. See the downloading or scheduling documentation pages for more information.
