## Best for

One footer row that sums every balance, with its label spanning the columns to the left

## Agent notes

- `totalBalance` sums every row of `demoData` once, ignoring the page and the selection; recompute it from the rows you pass in
- The footer label spans `visibleCount` minus 2, so hiding Balance from its header menu slides the total under Status

## When not to use

- Several statistics such as lowest, highest and average values: use [Summary Stats Footer](https://reui.io/components/data-grid/c-data-grid-25.md) (`get_example("c-data-grid-25")`)

## About Shadcn Data Grid

### When to use

- Admin and back office tables that sort, filter, paginate and select rows
- Spreadsheet style editing with cell selection, clipboard and inline edits
- Large record sets that need virtualized rows, columns or infinite scroll

### When not to use

- A short static list of rows with no sorting or paging: use [Table](https://reui.io/components/table.md) (`get_component("table")`)
- Records moved as cards between status columns: use [Kanban](https://reui.io/components/kanban.md) (`get_component("kanban")`)
- A folder or category hierarchy with no columns of data: use [Tree](https://reui.io/components/tree.md) (`get_component("tree")`)

### Agent notes

- With `manualPagination`, pass the server total to `useTable` as `rowCount` as well as `recordCount`, or the page buttons never render
- Give `useTable` a stable `getRowId` whenever rows can be pinned, reordered or virtualized
- Swap `DataGridTable` for `DataGridTableVirtual` when rows need virtualization or infinite scroll
