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.
{{<admonitiontype="note">}}
Annotations and alerts are not currently supported for tables.
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](#cell-type).
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:
If you need to hide columns, you can do so using [data transformations](ref:data-transformation), [field overrides](#field-overrides), or by [building a query](ref:build-query) that returns only the needed columns.
1. Click the checkbox next to the values that you want to display or click **Select all**.
1. 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.
1. 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").

| Enable pagination | Toggle 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 width | Define 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 width | Define 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 alignment | Set how Grafana should align cell contents. Choose from: **Auto** (default), **Left**, **Center**, or **Right**. |
| Column filter | Temporarily change how column data is displayed. For example, show or hide specific values. For more information, refer to [Column filtering](#column-filtering). |
There are several calculations you can choose from including minimum, maximum, first, last, and total.
For the full list of options, refer to [Calculations](ref:calculations).
In the table footer:
- You can apply multiple calculations at once.
- The calculations and reducer functions apply to all fields in the table, by default. To control which fields have a calculation or function applied, add the table footer in an override instead.
- If you enable a mathematical function for a non-numeric field, nothing for that function is displayed for that field.
In the following image, multiple calculations—**Mean**, **Max**, and **Last**—have been applied:
{{<figuresrc="/media/docs/grafana/panels-visualizations/screenshot-tablefooter-v12.2.png"max-width="750px"alt="Table with footer displaying mean, max, and last">}}
| [Colored text](#colored-text) | If thresholds, value mappings, or color schemes are set, then the cell text is displayed in the appropriate color. |
| [Colored background](#colored-background) | If thresholds, value mappings, or color schemes are set, then the cell background is displayed in the appropriate color. |
| [Gauge](#gauge) | Values are displayed as a horizontal bar gauge. You can set the [Gauge display mode](#gauge-display-mode) and the [Value display](#value-display) options. |
| [Sparkline](#sparkline) | Shows values rendered as a sparkline. |
The colored background cell type has the following options:
<!-- prettier-ignore-start -->
| Option | Description |
| ------ | ----------- |
| Background display mode | Choose between **Basic** and **Gradient**. |
| Apply to entire row | Toggle the switch on to apply the background color that's configured for the cell to the whole row. |
| Cell value inspect | <p>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**.</p><p>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.</p> |
| Tooltip from field | Toggle on the **Tooltip from field** switch to use the values from another field (or column) in a tooltip. For more information, refer to the [Tooltip from field](#tooltip-from-field). |
If 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.
| Gauge display mode | Controls the type of gauge used. For more information, refer to the [Gauge display mode](#gauge-display-mode). |
| Value display | Controls how the value is displayed. For more information, refer to the [Value display](#value-display). |
| Tooltip from field | Toggle on the **Tooltip from field** switch to use the values from another field (or column) in a tooltip. For more information, refer to [Tooltip from field](#tooltip-from-field). |
The maximum and minimum values of the gauges are configured automatically from the smallest and largest values in your whole dataset.
If you don't want the max/min values to be pulled from the whole dataset, you can configure them for each column using [field overrides](#field-overrides).
| Basic | Shows a simple gauge with the threshold levels defining the color of gauge. {{<figuresrc="/media/docs/grafana/panels-visualizations/screenshot-gauge-mode-basic-v11.3.png"alt="Table cell with basic gauge mode">}} |
| Gradient | The threshold levels define a gradient. {{<figuresrc="/media/docs/grafana/panels-visualizations/screenshot-gauge-mode-gradient-v11.3.png"alt="Table cell with gradient gauge mode">}} |
| Retro LCD | The gauge is split up in small cells that are lit or unlit. {{<figuresrc="/media/docs/grafana/panels-visualizations/screenshot-gauge-mode-retro-v11.3.png"alt="Table cell with retro LCD gauge mode">}} |
| Value color | Labels are colored by value. {{<figuresrc="/media/docs/grafana/panels-visualizations/screenshot-labels-value-color-v11.3.png"alt="Table with labels in value color">}} |
| Text color | Labels match the theme text color. {{<figuresrc="/media/docs/grafana/panels-visualizations/screenshot-labels-text-color-v11.3.png"alt="Table with labels in theme color">}} |
| Hidden | Labels are hidden. {{<figuresrc="/media/docs/grafana/panels-visualizations/screenshot-labels-hidden-v11.3.png"alt="Table with labels hidden">}} |
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](ref:time-series-to-table-transformation) to process it into a format the table can show.
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](ref:graph-styles).
| Hide value | Toggle the switch on or off to display or hide the cell value on the sparkline. |
| Style | Choose 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 interpolation | How the graph interpolates the series line. Choose from:<ul><li>**Linear** - Points are joined by straight lines.</li><li>**Smooth** - Points are joined by curved lines that smooths transitions between points.</li><li>**Step before** - The line is displayed as steps between points. Points are rendered at the end of the step.</li><li>**Step after** - The line is displayed as steps between points. Points are rendered at the beginning of the step.</li></ul> |
| Line width | The thickness of the series lines or the outline for bars using the **Line width** slider. |
| Fill opacity | The series area fill color using the **Fill opacity** slider. |
| Gradient mode | Gradient 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](ref:color-scheme). Choose from:<ul><li>**None** - No gradient fill. This is the default setting.</li><li>**Opacity** - An opacity gradient where the opacity of the fill increases as y-axis values increase.</li><li>**Hue** - A subtle gradient that's based on the hue of the series color.</li></ul> |
| Line style | Choose from:<ul><li>**Solid**</li><li>**Dash** - Select the length and gap for the line dashes. Default dash spacing is 10, 10.</li><li>**Dots** - Select the gap for the dot spacing. Default dot spacing is 0, 10.</li></ul> |
| Connect null values | How 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:<ul><li>**Never** - Time series data points with gaps in the data are never connected.</li><li>**Always** - Time series data points with gaps in the data are always connected.</li><li>**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.</li></ul> |
| Show points | Whether to show data points to lines or bars. Choose from: <ul><li>**Auto** - Grafana determines a point's visibility based on the density of the data. If the density is low, then points appear.</li><li>**Always** - Show the points regardless of how dense the dataset is.</li><li>**Never** - Don't show points.</li></ul> |
| Point size | Set the size of the points, from 1 to 40 pixels in diameter. |
| Bar alignment | Set the position of the bar relative to a data point. |
| Tooltip from field | Toggle on the **Tooltip from field** switch to use the values from another field (or column) in a tooltip. For more information, refer to [Tooltip from field](#tooltip-from-field). |
For the JSON view cell type, you can set enable **Cell value inspect**.
This 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**.
in these cells if the [`disable_sanitize_html`](https://grafana.com/docs/grafana/<GRAFANA_VERSION>/setup-grafana/configure-grafana/#disable_sanitize_html) option is set to true for your Grafana instance.
| Alt text | Set the alternative text of an image. The text will be available for screen readers and in cases when images can't be loaded. |
| Title text | Set the text that's displayed when the image is hovered over with a cursor. |
| Tooltip from field | Toggle on the **Tooltip from field** switch to use the values from another field (or column) in a tooltip. For more information, refer to [Tooltip from field](#tooltip-from-field). |
| Method | Choose from **GET**, **POST**, and **PUT**. |
| Content-Type | Select an option in the drop-down list. Choose from: JSON, Text, JavaScript, HTML, XML, and x-www-form-urlencoded. |
| Query parameters | Enter as many **Key**, **Value** pairs as you need. |
| Header parameters | Enter as many **Key**, **Value** pairs as you need. |
| Payload | Enter the body of the API call. |
| Tooltip from field | Toggle on the **Tooltip from field** switch to use the values from another field (or column) in a tooltip. For more information, refer to [Tooltip from field](#tooltip-from-field). |
Hover your mouse over the chip to display the tooltip.
When you toggle on the switch, the **Tooltip placement** option, which controls where the tooltip box opens upon hover, is also displayed.
Select one of the following options: **Auto**, **Top**, **Right**, **Bottom**, and **Left**.
The content of the tooltip is determined by the values of the source field and can't be directly edited.
However, you can affect the display of the value using overrides like value mappings, as shown in the [Example: Tooltip from field with value mappings](#example-tooltip-from-field-with-value-mappings) section.
While you can turn on this option under **Cell options**, and have it applied to all cells in the table, it's typically used as an override on a sub-set of cells instead.
This is demonstrated in the example in the following section.
##### Example: Tooltip from field using overrides
The following table has five visible fields (columns) as well as a hidden field called "Info":
{{<figuresrc="/media/docs/grafana/panels-visualizations/screenshot-tooltip-table-1-v12.2.png"max-width="750px"alt="Table that includes a hidden column">}}
- The "Info" field is hidden using the **Table > Hide in table** override property.
- The following overrides have been applied to the "Short text" field:
- The values from the "Info" field are used as tooltip text for the "Short text" cells using the **Cell options > Tooltip from field** override property.
- The **Cell options > Tooltip placement** override property is set to control the placement of the tooltip.
{{<figuresrc="/media/docs/grafana/panels-visualizations/screenshot-tooltip-override-2-v12.2.png"max-width="300px"alt="Override to use the Info field values as tooltips for the Short text column">}}
Now, when you hover the cursor over the chip in the "Short text" column, the corresponding values from the "Info" column appear in the tooltip:
{{<figuresrc="/media/docs/grafana/panels-visualizations/screenshot-tooltip-on-hover-v12.2.png"max-width="750px"alt="Info field value in the tooltip of the Short text cell upon hover">}}
##### Example: Tooltip from field with value mappings
While the content of the tooltip is determined by the values of the source field and can't be directly edited, you can use field overrides on the source field to manipulate the display of that value.
For example, if the "Info" column is being used as the source field for the tooltip values, you could set up a value mapping.
In this case, the value "up" is mapped to the word "Good":
{{<figuresrc="/media/docs/grafana/panels-visualizations/screenshot-tooltip-value-map-v12.2.png"max-width="750px"alt="Info field value up being mapped to the value Good in an override">}}
Now, when you hover the cursor over the chip in the "Short text" cell, the mapped value appears in the tooltip:
{{<figuresrc="/media/docs/grafana/panels-visualizations/screenshot-tooltip-on-hover-2-v12.2.png"max-width="750px"alt="Info field mapped to a new value in the tooltip of the Short text cell upon hover">}}
You can use all field overrides to affect the display of the tooltip.
For example, the **Table > Column width** or **Cell options > Cell type** overrides can change the cell width or visual display of the data.
