## Best for

Order rows that expand into a nested grid of line items, each with its own sorting and paging

## Agent notes

- Each expanded order mounts `OrderItemsSubTable`, a separate `DataGrid` and `useTable` over that order's `items`, so its sort and page state are its own

## When not to use

- A short line of text under a row rather than a nested list: use [Expandable Rows](https://reui.io/components/data-grid/c-data-grid-8.md) (`get_example("c-data-grid-8")`)

## 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
