## Feature explanations and examples

- [Grouping and aggregation](https://grid.syidax.com/docs/features/row-grouping.md) — Row grouping collects source rows with the same region or team into expandable groups. Unlike column groups, which organize headers, row groups change displayed rows and aggregation results.
