The table footer displays the results of calculations (and reducer functions) on fields.
The footer is only displayed after you select an option in the **Calculation** drop-down list:

There are several calculations you can choose from including minimum, maximum, first, last, and total.

In the table footer:
- You can apply multiple calculations at once.
- All calculations and reducer functions are labeled except **Total** when it's the only function applied.
- 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&mdash;**Mean**, **Max**, and **Last**&mdash;have been applied:
{{< figure src="/media/docs/grafana/panels-visualizations/screenshot-table-footer-1-v12.2.png" max-width="750px" alt="" >}}
{{< figure src="/media/docs/grafana/panels-visualizations/screenshot-tablefooter-v12.2.png" max-width="750px" alt="Table with footer displaying mean, max, and last" >}}
You can also see in the previous image that the mathematical functions, **Mean** and **Max**, haven't been applied to the text field in the table.
Only the **Last** function has been applied to that field.
In the following image, the **Total** calculation has been applied, and no label is displayed because it's the only function:

Calculations applied to cell types like **Markdown + HTML** might have unexpected results.
