> Render the slotsmith data table in markup of your own with useDataTable: the state, the TanStack Table instance and row reorder, with no UI.

`useDataTable` is the data table without its markup: it holds the state, builds the TanStack Table instance and runs row reorder, and you render every element yourself. `<DataTable>` calls it for you; use it directly when no slot replacement gets you the markup you need.

```tsx
import { flexRender } from "@tanstack/react-table";
import { useState, type CSSProperties } from "react";
import { useDataTable, type DataTableColumnDef, type DataTableLabels } from "slotsmith/data-table";

type Track = { id: string; title: string; artist: string; length: string };

const playlist: Track[] = [
  { id: "1", title: "Morning Light", artist: "The Harbour", length: "3:41" },
  { id: "2", title: "Paper Boats", artist: "Mina Sol", length: "4:05" },
  { id: "3", title: "Slow Tide", artist: "The Harbour", length: "5:12" },
  { id: "4", title: "North Road", artist: "Kai Brenner", length: "3:28" },
  { id: "5", title: "Last Train", artist: "Mina Sol", length: "4:47" },
];

const columns: DataTableColumnDef<Track>[] = [
  { accessorKey: "title", header: "Title" },
  { accessorKey: "artist", header: "Artist" },
  { accessorKey: "length", header: "Length" },
];

// The hook reads the reorder labels; any left out stay English.
const labels: Partial<DataTableLabels> = {
  reorderRow: "Move track",
  reorderInstructions: "Press space to pick the track up, the arrow keys to move it, space to put it down, escape to cancel.",
  reorderCancelled: "Move cancelled.",
};

const cellStyle: CSSProperties = { padding: "0.375rem 0.5rem", borderBlockEnd: "1px solid", textAlign: "start" };
// No `outline` here: the handle keeps the browser's focus ring, so keyboard users can see which handle has focus.
const handleStyle: CSSProperties = { font: "inherit", color: "inherit", background: "none", border: 0, padding: "0 0.25rem" };
const hidden: CSSProperties = { position: "absolute", width: 1, height: 1, overflow: "hidden", clipPath: "inset(50%)", whiteSpace: "nowrap" };

export default function HeadlessHook() {
  const [tracks, setTracks] = useState(playlist);
  const { table, reorder } = useDataTable({
    data: tracks,
    columns,
    getRowId: (track) => track.id,
    enablePagination: false,
    enableRowReorder: true,
    onRowOrderChange: (change) => setTracks(change.data),
    labels,
  });

  return (
    <>
      <table style={{ width: "100%", borderCollapse: "collapse" }}>
        <thead>
          {table.getHeaderGroups().map((group) => (
            <tr key={group.id}>
              <th style={cellStyle}>
                <span style={hidden}>Order</span>
              </th>
              {group.headers.map((header) => (
                <th key={header.id} style={cellStyle}>
                  {flexRender(header.column.columnDef.header, header.getContext())}
                </th>
              ))}
            </tr>
          ))}
        </thead>
        <tbody>
          {table.getRowModel().rows.map((row) => {
            // data-row-id always; data-dragging and data-drop-edge during a drag.
            const attributes = reorder.getRowProps(row.id);
            const handle = reorder.getHandleProps(row.id);
            const lifted = attributes["data-dragging"] !== undefined;
            const edge = attributes["data-drop-edge"];
            return (
              <tr
                key={row.id}
                {...attributes}
                style={{
                  position: lifted ? "relative" : undefined,
                  background: lifted ? "Canvas" : undefined,
                  boxShadow: edge === "before" ? "inset 0 2px 0 0 currentColor" : edge === "after" ? "inset 0 -2px 0 0 currentColor" : undefined,
                }}
              >
                <td style={cellStyle}>
                  <button type="button" {...handle} style={{ ...handle.style, ...handleStyle, cursor: lifted ? "grabbing" : "grab" }}>
                    ⠿
                  </button>
                </td>
                {row.getAllCells().map((cell) => (
                  <td key={cell.id} style={cellStyle}>
                    {flexRender(cell.column.columnDef.cell, cell.getContext())}
                  </td>
                ))}
              </tr>
            );
          })}
        </tbody>
      </table>
      {/* Every handle's aria-describedby points here. */}
      <div id={reorder.instructionsId} hidden>
        {labels.reorderInstructions}
      </div>
      {/* Always rendered: a live region added at the moment it changes is not read. */}
      <div role="status" aria-live="assertive" aria-atomic="true" style={hidden}>
        {reorder.announcement}
      </div>
    </>
  );
}
```

The demo renders a plain `<table>` with no slotsmith class or stylesheet. Its rows still reorder by pointer, touch and keyboard, with the handle named "Move track" from its own labels.

## Options

`useDataTable` takes the same data and state options as the `DataTable` [props](https://slotsmith.dev/ar/components/data-table/api/#props): `data`, `columns`, `getRowId`, sorting, pagination, selection, expansion, `loading`, `error`, `enableRowReorder` and `onRowOrderChange`, each controlled or not in the same way. What it leaves out is everything about the markup: slots, `slotProps`, the size and `locale`.

One option is the hook's own: `labels`. It reads the six reorder keys, the handle's name, its instructions and the announcements; a key you leave out stays English. `<DataTable>` passes its own `labels` and `locale` to the hook instead.

## What it returns

- `table`: the TanStack Table instance. Render the header groups, rows and cells from it with `flexRender` from `@tanstack/react-table`, as the demo does.
- `status`: `"loading"`, `"error"`, `"empty"` or `"ready"`, for what the body should show; `error` and `onRetry` are the options as passed.
- `selection`: the selected rows, including rows on other server pages, and `getRowKey`, the id of any row.
- `selectable`, `expandable`, `paginationEnabled` and `pageSizeOptions`: what the options turned on.
- `reorder`, `reorderable` and `reorderHandleColumn`: row reorder, below.

## Row reorder in your own markup

`reorder` is the engine `<DataTable>` uses. Wire it up in four places:

- Spread `reorder.getRowProps(rowId)` on each body row. It gives `data-row-id` always, and during a drag `data-dragging`, `data-dragging-child`, `data-drop-position` and `data-drop-edge`; the demo reads them to draw the lifted row and the drop line.
- Spread `reorder.getHandleProps(rowId)` on a `<button>` in each row. It carries the handlers, `aria-label`, `aria-describedby`, `aria-pressed`, `disabled` and `touch-action: none`.
- Render an element with the id `reorder.instructionsId`, hidden, holding the instructions text.
- Render `reorder.announcement` in a live region (`role="status"`, `aria-live="assertive"`) that is always in the page: a live region added at the moment it changes is not read.

The rows must be siblings in one parent element, such as a `<tbody>`, because the engine measures and moves them there. `reorder.draggingId` and `reorder.target` give the drag state, and `reorder.enabled` says whether a drag can start now. Storing the order works as in the [row reorder](https://slotsmith.dev/ar/components/data-table/guides/row-reorder/) guide.

## Between the two

To keep most of the table and replace one region, there is a middle way: `DataTable.Provider` runs the hook and shares its result, `DataTable.Root`, `DataTable.Table` and `DataTable.Pagination` render the parts, and `useDataTableContext()` reads the same model inside any component you put among them.
