# Rollup column

A rollup column aggregates data from related records in a linked table and displays the aggregated result in the current table. Use rollup columns to calculate values like sum, count, average, minimum, maximum, and median, as well as advanced ones like latest date, earliest date, countA, empty, and many more.

For example, a rollup column can display the total hours logged for a project, the number of open tasks assigned to an employee, or the total value of orders associated with a product or a customer.

This article explains how to create and configure a rollup column.

### Add rollup column

1. Go to **PowerTable** > **Insert Column** > **Visual Column** > **Add Roll Up Column**.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.fabricplan.com/documentation/plan/powertable-sheets/how-tos/adding-columns-overview/add-visual-column/rollup-column.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
