Grafana Cloud Enterprise Open source

Table

Tables are very flexible, supporting multiple modes for time series and for tables, annotation, and raw JSON data. This visualization also provides date formatting, value formatting, and coloring options.

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:

Give it a try using Grafana Play

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.

Annotation and alert support

Annotations and alerts are not currently supported in tables.

Sort column

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

Table options

Note

If you are using a table created before Grafana 7.0, then you need to migrate to the new table version in order to see these options. To migrate, on the Panel tab, click Table visualization. Grafana updates the table version and you can then access all table options.

Show header

Show or hide column names imported from your data source.

Column width

By default, Grafana automatically calculates the column width based on the table size and the minimum column width. This field option can override the setting and define the width for all columns in pixels.

For example, if you enter 100 in the field, then when you click outside the field, all the columns will be set to 100 pixels wide.

Minimum column width

By default, the minimum width of the table column is 150 pixels. This field option can override that default and will define the new minimum column width for the table in pixels.

For example, if you enter 75 in the field, then when you click outside the field, all the columns will scale to no smaller than 75 pixels wide.

For small-screen devices, such as smartphones or tablets, reduce the default 150 pixel value to50 to allow table-based panels to render correctly in dashboards.

Column alignment

Choose how Grafana should align cell contents:

  • Auto (default)
  • Left
  • Center
  • Right

Cell type

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

Note

If you set these in the Field tab, then the type will apply to all fields, including the time field. Many options will work best if you set them in the Override tab so that they can be restricted to one or more fields.

Color text

If thresholds are set, then the field text is displayed in the appropriate threshold color.

Color background (gradient or solid)

If thresholds are set, then the field background is displayed in the appropriate threshold color.

Gauge

Cells can be displayed as a graphical gauge, with several different presentation types.

Basic

The basic mode will show a simple gauge with the threshold levels defining the color of gauge.

Gradient gauge

Gradient

The threshold levels define a gradient.

LCD

The gauge is split up in small cells that are lit or unlit.

Label Options

Additionally, labels displayed alongside of the gauges can be set to be colored by value, match the theme text color, or be hidden.

If you’ve configured data links, when the cell type is Auto mode, 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 view

Shows value formatted as code. If a value is an object the JSON view allowing browsing the JSON object will appear on hover.

Image

Only available in Grafana 7.3+

If you have a field value that is an image URL or a base64 encoded image you can configure the table to display it as an image.

Table hover

Sparkline

Shows value rendered as a sparkline. Requires time series to table data transform.

Cell value inspect

Enables value inspection from table cell. The raw value is presented in a modal window.

Note

Cell value inspection is only available when cell display mode is set to Auto, Color text, Color background or JSON View.

Column filter

You can temporarily change how column data is displayed. For example, you can order values from highest to lowest or hide specific values. For more information, refer to Filter table columns.

Pagination

Use this option to enable or disable pagination. It is a front-end option that does not affect queries. When enabled, the page size automatically adjusts to the height of the table.

Filter table columns

If you turn on the Column filter, then you can filter table options.

Turn on column filtering

  1. In Grafana, navigate to the dashboard with the table with the columns that you want to filter.
  2. On the table panel you want to filter, open the panel editor.
  3. Click the Field tab.
  4. In Table options, turn on the Column filter option.

A filter icon appears next to each column title.

Filter column values

To filter column values, click the filter (funnel) icon next to a column title. Grafana displays the filter options for that column.

Filter column values
Filter column values

Click the check box next to the values that you want to display. 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.

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: =, !=, <, <=, >, >=.

Click the check box above the Ok and Cancel buttons to add or remove all displayed values to/from the filter.

Clear column filters

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

Filtered column

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

You can use the table footer to show calculations on fields.

After you enable the table footer:

  1. Select the Calculation
  2. Select the Fields that you want to calculate

The system applies the calculation to all numeric fields if you do not select a field.

Count rows

If you want to show the number of rows in the dataset instead of the number of values in the selected fields, select the Count calculation and enable Count rows.

Data links allow you to link to other panels, dashboards, and external resources while maintaining the context of the source panel. You can create links that include the series name or even the value under the cursor.

For each data link, set the following options:

  • Title
  • URL
  • Open in new tab

To learn more, refer to Configure data links.

Thresholds

A threshold is a value or limit you set for a metric that’s reflected visually when it’s met or exceeded. Thresholds are one way you can conditionally style and color your visualizations based on query results.

Set the following options:

  • Value - Set the value for each threshold.
  • Thresholds mode - Choose from:
    • Absolute
    • Percentage

To learn more, refer to Configure thresholds.

Value mappings

Value mapping is a technique you can use to change how data appears in a visualization.

For each value mapping, set the following options:

  • Condition - Choose what’s mapped to the display text and (optionally) color:
    • Value - Specific values
    • Range - Numerical ranges
    • Regex - Regular expressions
    • Special - Special values like Null, NaN (not a number), or boolean values like true and false
  • Display text
  • Color (Optional)
  • Icon (Canvas only)

To learn more, refer to Configure value mappings.

Field overrides

Overrides allow you to customize visualization settings for specific fields or series. When you add an override rule, it targets a particular set of fields and lets you define multiple options for how that field is displayed.

Choose from one the following override options:

  • Fields with name - Select a field from the list of all available fields.
  • Fields with name matching regex - Specify fields to override with a regular expression.
  • Fields with type - Select fields by type, such as string, numeric, or time.
  • Fields returned by query - Select all fields returned by a specific query, such as A, B, or C.
  • Fields with values - Select all fields returned by your defined reducer condition, such as Min, Max, Count, Total.

To learn more, refer to Configure field overrides.
