Table

Tables are a highly flexible visualization designed to display data in columns and rows. The table visualization can take multiple datasets and provide the option to switch between them. With this versatility, it’s the preferred visualization for viewing multiple data types, aiding in your data analysis needs.

Basic table visualization

You can use a table visualization to show datasets such as:

  • Common database queries like logs, traces, metrics
  • Financial reports
  • Customer lists
  • Product catalogs

Any information you might want to put in a spreadsheet can often be best visualized in a table.

Tables also provide different styles to visualize data inside the table cells, such as colored text and cell backgrounds, gauges, sparklines, data links, JSON code, and images.

Note

Annotations and alerts are not currently supported for tables.

Configure a table visualization

The following video provides a visual walkthrough of the options you can set in a table visualization. If you want to see a configuration in action, check out the video:

With Grafana Play, you can explore and see how it works, learning from practical examples to accelerate your development. This feature can be seen on Table Visualizations in Grafana.

Supported data formats

The table visualization supports any data that has a column-row structure.

Note

If you’re using a cell type such as sparkline or JSON, the data requirements may differ in a way that’s specific to that type. For more info refer to Cell type.

Example

This example shows a basic dataset in which there’s data for every table cell:

csv
Column1, Column2, Column3
value1 , value2 , value3
value4 , value5 , value6
value7 , value8 , value9

If a cell is missing or the table column-row structure is not complete, as in the following example, the table visualization won’t display any of the data:

csv
Column1, Column2, Column3
value1 , value2 , value3
gap1   , gap2
value4 , value5 , value6

If you need to hide columns, you can do so using data transformations, field overrides, or by building a query that returns only the needed columns.

Column filtering

You can temporarily change how column data is displayed using column filtering. For example, you can show or hide specific values.

Turn on column filtering

To turn on column filtering, follow these steps:

  1. In Grafana, navigate to the dashboard with the table with the columns that you want to filter.
  2. Hover over any part of the panel to which you want to add the link to display the actions menu on the top right corner.
  3. Click the menu and select Edit.
  4. In the panel editor pane, expand the Table options section.
  5. Toggle on the Column filter switch.

A filter icon (funnel) appears next to each column title.

Column filtering turned on

Filter column values

To filter column values, follow these steps:

  1. Click the filter icon (funnel) next to a column title.

    Grafana displays the filter options for that column.

    Filter column values
  2. Click the checkbox next to the values that you want to display or click Select all.

  3. Enter text in the search field at the top to show those values in the display so that you can select them rather than scroll to find them.

  4. Choose from several operators to display column values:

    • Contains - Matches a regex pattern (operator by default).
    • Expression - Evaluates a boolean expression. The character $ represents the column value in the expression (for example, “$ >= 10 && $ <= 12”).
    • The typical comparison operators: =, !=, <, <=, >, >=.
  5. Click the checkbox above the Ok and Cancel buttons to add or remove all displayed values to and from the filter.

Clear column filters

Columns with filters applied have a blue filter displayed next to the title.

Filtered column

To remove the filter, click the blue filter icon and then click Clear filter.

Sort columns

Click a column title to change the sort order from default to descending to ascending. Each time you click, the sort order changes to the next option in the cycle. You can sort multiple columns by holding the Shift key and clicking the column name.

Sort descending

Dataset selector

If the data queried contains multiple datasets, a table displays a drop-down list at the bottom, so you can select the dataset you want to visualize. This option is only available when you’re editing the panel.

Configuration options

Panel options

In the Panel options section of the panel editor pane, set basic options like panel title and description, as well as panel links. To learn more, refer to Configure panel options.

Table options

OptionDescription
Show table headerShow or hide column names imported from your data source.
Cell heightSet the height of the cell. Choose from Small, Medium, or Large.
Enable paginationToggle the switch to control how many table rows are visible at once. When switched on, the page size automatically adjusts to the height of the table. This option doesn’t affect queries.
Minimum column widthDefine the lower limit of the column width, in pixels. By default, the minimum width of the table column is 150 pixels. For small-screen devices, such as mobile phones or tablets, reduce the value to 50 to allow table-based panels to render correctly in dashboards.
Column widthDefine a column width, in pixels, rather than allowing the width to be set automatically. By default, Grafana calculates the column width based on the table size and the minimum column width.
Column alignmentSet how Grafana should align cell contents. Choose from: Auto (default), Left, Center, or Right.
Column filterTemporarily change how column data is displayed. For example, show or hide specific values. For more information, refer to Column filtering.

Toggle the Show table footer switch on and off to control the display of the footer. When the toggle is switched on, you can use the table footer to show calculations on fields.

After you activate the table footer, make selections for the following options:

  • Calculation - The calculation that you want to apply.
  • Count rows - This option is displayed if you select the Count calculation. If you want to show the number of rows in the dataset instead of the number of values in the selected fields, toggle on the Count rows switch.
  • Fields - The fields to which you want to apply the calculation. Grafana applies the calculation to all numeric fields if you don’t select a field.

Cell options

Cell options allow you to control how data is displayed in a table. The options are differ based on the cell type that you select and are outlined within the descriptions of each cell type. The following table provides short descriptions for each cell type and links to a longer description and the cell type options.

Cell type

By default, Grafana automatically chooses display settings. You can override these settings by choosing one of the following cell types to control the default display for all fields. Additional configuration is available for some cell types.

If you want to apply a cell type to only some fields instead of all fields, you can do so using the Cell options > Cell type field override.

Cell typeDescription
AutoA basic text and number cell.
SparklineShows values rendered as a sparkline.
Colored textIf thresholds, value mappings, or color schemes are set, then the cell text is displayed in the appropriate color.
Colored backgroundIf thresholds, value mappings, or color schemes are set, then the cell background is displayed in the appropriate color.
GaugeValues are displayed as a horizontal bar gauge. You can set the Gauge display mode and the Value display options.
Data linksIf you’ve configured data links, when the cell type is Auto, the cell text becomes clickable. If you change the cell type to Data links, the cell text reflects the titles of the configured data links. To control the application of data link text more granularly, use a Cell option > Cell type > Data links field override.
JSON ViewShows values formatted as code.
ImageDisplays an image when the value is a URL or a base64 encoded image.
ActionsThe cell displays a button that triggers a basic, unauthenticated API call when clicked.

Auto

This is a basic text and number cell.

It has the following cell options:

OptionDescription
Wrap text

Toggle the Wrap text switch to wrap text in the cell that contains the longest content in your table. To wrap the text in a specific column only, use a Fields with name field override, select the Cell options > Cell type override property, and toggle on the Wrap text switch.

Text wrapping is in public preview, however, it’s available to use by default.

Cell value inspect

Enables value inspection from table cells. When the switch is toggled on, clicking the inspect icon in a cell opens the Inspect value drawer which contains two tabs: Plain text and Code editor.

Grafana attempts to automatically detect the type of data in the cell and opens the drawer with the associated tab showing. However, you can switch back and forth between tabs.

Sparkline

This cell type shows values rendered as a sparkline. To show sparklines on data with multiple time series, use the Time series to table transformation to process it into a format the table can show.

Table using sparkline cell type

The sparkline cell type options are described in the following table. For more detailed information about all of the sparkline styling options (except Hide value), refer to the time series graph styles documentation.

OptionDescription
Hide valueToggle the switch on or off to display or hide the cell value on the sparkline.
StyleChoose whether to display your time-series data as Lines, Bars, or Points. You can use overrides to combine multiple styles in the same graph.
Line interpolationHow the graph interpolates the series line. Choose from:
  • Linear - Points are joined by straight lines.
  • Smooth - Points are joined by curved lines that smooths transitions between points.
  • Step before - The line is displayed as steps between points. Points are rendered at the end of the step.
  • Step after - The line is displayed as steps between points. Points are rendered at the beginning of the step.
Line widthThe thickness of the series lines or the outline for bars using the Line width slider.
Fill opacityThe series area fill color using the Fill opacity slider.
Gradient modeGradient mode controls the gradient fill, which is based on the series color. Gradient appearance is influenced by the Fill opacity setting. To change the color, use the standard color scheme field option. For more information, refer to Color scheme. Choose from:
  • None - No gradient fill. This is the default setting.
  • Opacity - An opacity gradient where the opacity of the fill increases as y-axis values increase.
  • Hue - A subtle gradient that’s based on the hue of the series color.
Line styleChoose from:
  • Solid
  • Dash - Select the length and gap for the line dashes. Default dash spacing is 10, 10.
  • Dots - Select the gap for the dot spacing. Default dot spacing is 0, 10.
Connect null valuesHow null values, which are gaps in the data, appear on the graph. Null values can be connected to form a continuous line or set to a threshold above which gaps in the data are no longer connected. Choose from:
  • Never - Time series data points with gaps in the data are never connected.
  • Always - Time series data points with gaps in the data are always connected.
  • Threshold - Specify a threshold above which gaps in the data are no longer connected. This can be useful when the connected gaps in the data are of a known size or within a known range, and gaps outside this range should no longer be connected.
Show pointsWhether to show data points to lines or bars. Choose from:
  • Auto - Grafana determines a point’s visibility based on the density of the data. If the density is low, then points appear.
  • Always - Show the points regardless of how dense the dataset is.
  • Never - Don’t show points.
Point sizeSet the size of the points, from 1 to 40 pixels in diameter.
Bar alignmentSet the position of the bar relative to a data point.

Colored text

If thresholds, value mappings, or color schemes are set, the cell text is displayed in the appropriate color.

Table with colored text cell type
