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.
1. In Grafana, navigate to the dashboard with the table with the columns that you want to filter.
1. On the table panel you want to filter, open the panel editor.
1. Expand the the **Table** options section.
1. Toggle on the [**Column filter** switch](#table-options).
If the data queried contains multiple data sets, a table displays a drop-down list at the bottom, so you can select the data set you want to visualize.
### 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.
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.
## Table options
Choose from several operators to display column values:
{{% admonition type="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.
{{% /admonition %}}
- **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").
Show or hide column names imported from your data source.
To remove the filter, click the blue funnel icon and then click **Clear filter**.
### Column width
## Sort columns
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.
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.
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.
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.
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.
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.
{{<figuresrc="/media/docs/grafana/panels-visualizations/TablePanelMultiSet.png"max-width="650px"alt="Table visualization with multiple datasets"class="docs-image--no-shadow">}}
For small-screen devices, such as smartphones or tablets, reduce the default `150` pixel value to`50` to allow table-based panels to render correctly in dashboards.
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.

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](#filter-table-columns).
| Show table header | Show or hide column names imported from your data source. |
| Cell height | Set the height of the cell. Choose from **Small**, **Medium**, and **Large**. |
| 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 smartphones or tablets, reduce the default `150` pixel 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**, and **Right**. |
| Column filter | 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](#filter-table-columns). |
### Pagination
### Table footer options
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.
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](ref:calculations) on fields.
## Cell options
After you activate the table footer, make selections in the following options:
### Cell type
- **Calculation** - The calculation that you want to apply.
- **Fields** - The fields to which you want to apply the calculations. The system applies the calculation to all numeric fields if you do not select a field.
- **Count rows** - This options 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.
### Cell options
Cell options allow you to control how data is displayed in a table.

The **Auto** cell type automatically displays values, with sensible defaults applied.
You can customize sparklines with many of the same options as the [time series visualization](ref:time-series-panel) including line style and width, fill opacity, gradient mode, and more.
