# Data Table (Notchset): prompt.md (v1.0.0)

- id: `data-table` · version 1.0.0 · component · pro (Pro)
- category: Data
- build: Base UI (one set of files; its dependencies follow the build)
- install (this build): `npx shadcn@latest add @beautiful-ui-pro/data-table`
- npm dependencies: none
- registry dependencies: utils, https://beautiful-ui.dev/r/notchset-foundation.json
- docs: https://beautiful-ui.dev/components/data-table
- The install command carries everything this item needs (files, CSS, tokens, npm and registry dependencies). Prefer it to copying source by hand.

A data table whose rows glide to their new slots when sorted and fade in place when filtered, with sortable headers, a tinted sorted column, tri-state selection and a footer that turns into your actions.

## Build it
- Stack: React 19 (`ref` is a plain prop), TypeScript, Tailwind CSS v4 utilities, a shadcn-initialised project with the `@/*` alias.
- Packages: none beyond React.
- Files: `components/ui/notchset/data-table.tsx`; shared code: `lib/beautiful-ui/notchset/instrument.tsx`, `lib/beautiful-ui/notchset/root.ts`, `lib/beautiful-ui/notchset/calendar.tsx`.
- Registry dependencies, installed with it automatically: shadcn `utils` (cn), `notchset-foundation`.
- Builds: one set of files for both, but its dependencies come in Base UI and Radix builds. Install the one that matches the project (see Install): a free item's bare URL installs the Base UI build of it and its dependencies.
- Exports to keep: `DataTable`, `ScaleCell`, `StatusCell`, and every exported type.
- CSS: the install adds the notchset foundation (tokens, keyframes, motion levels) to your global stylesheet once. Nothing to import by hand.
- Re-running `add` (or `--overwrite`) re-applies those rules: put overrides in your own CSS, never in the installed rules.
- Tokens: retheme with the `--notchset-*` custom properties (`--notchset-check`, `--notchset-control-edge`, `--notchset-draw-from`, `--notchset-ease-bloom`, `--notchset-ease-travel`, `--notchset-fade`, `--notchset-focus-color`, `--notchset-focus-inset`, `--notchset-life-from`, `--notchset-life-ms`, `--notchset-node-blink`, `--notchset-node-bloom`, `--notchset-node-delay`, `--notchset-plate-color`, `--notchset-rise-from`, `--notchset-rule`, `--notchset-scroll`, `--notchset-signal`, `--notchset-sweep-to`). Never add Tailwind colour classes inside the component.

```tsx
import { DataTable, StatusCell, type DataColumn } from "@/components/ui/notchset/data-table";
```

## Parts

| Part | data-slot | What it is for |
|---|---|---|
| `DataTable` | `data-table` | The table. |
| `StatusCell` | — | OK, failed or running. |
| `ScaleCell` | — | A value on a small scale. |

Style a part with `[data-slot="<slot>"]` selectors or its `className`; keep the attributes when editing.

## Sound
- Keep every `data-slot` and `data-sound` attribute: the sound layer reads them.
- Installing this item adds no audio. Nothing plays until the app mounts `SoundProvider` once (install: `npx shadcn@latest add https://beautiful-ui.dev/r/notchset-sound.json`, import from `@/components/ui/notchset/sound-provider`); `useSound()` gives `muted` and `setMuted` for a mute control. Without a provider the audio engine never loads.

## Match the original
- Read `components/ui/notchset/data-table.tsx` as the reference implementation before changing or recreating anything, and match it: sizes, colours per theme, motion timings, copy and behaviour.
- If you deviate (a prop you can't honour, a style you changed, a dependency you swapped), say so in your reply, part by part.
- Keep the accessibility contract, the keyboard map and the motion levels listed below.

## Use it when
- data table, table, sortable table, runs table, selection, bulk actions, admin table, Notchset
- Tens to a few hundred rows to sort, filter and act on

### Not when
- Thousands of rows: page or virtualise them first

## Mistakes
- Keep filtered rows in rows and pass visible, or they can't fade out

## Usage

```tsx
import { DataTable, StatusCell, type DataColumn } from "@/components/ui/notchset/data-table";

type Run = { id: string; agent: string; status: "ok" | "fail"; cost: number };

const columns: DataColumn<Run>[] = [
  { key: "id", header: "RUN", width: "110px" },
  { key: "agent", header: "AGENT", width: "minmax(110px,1fr)", sortable: true },
  { key: "status", header: "STATUS", width: "96px", cell: (r) => <StatusCell status={r.status} /> },
  { key: "cost", header: "COST", width: "90px", align: "end", sortable: true, cell: (r) => `$${r.cost.toFixed(4)}` },
];
const runs: Run[] = [
  { id: "run_8f3a1", agent: "Planner", status: "ok", cost: 0.0021 },
  { id: "run_8f3a2", agent: "Triage", status: "fail", cost: 0.0007 },
];

export function RunsTable() {
  return <DataTable columns={columns} rows={runs} defaultSort={{ key: "cost", dir: -1 }} />;
}
```

## Props

| Prop | Type | Default | What it does |
|---|---|---|---|
| `columns` | `{ key, header, width, align?, sortable?, sortValue?, cell? }[]` |  | Grid tracks and cells. |
| `rows` | `{ id }[]` |  | Every row. |
| `visible` | `(row) => boolean` |  | Which rows pass your filters. |
| `defaultSort` | `{ key, dir }` |  | Starting sort. |
| `selected / onSelectedChange` | `string[]` |  | Selection. |
| `footer / selectionActions` | `render functions` |  | The footer at rest, and while rows are selected. |

## Customising
- Colours: the component reads your shadcn tokens (`--background`, `--foreground`, `--border` …), refined by the `--notchset-*` tokens. The signal colour is `--notchset-signal` (it falls back to `--destructive`). Set tokens on `:root`, or on any container to retheme one area.
- Dark mode follows the `.dark` class on an ancestor (the shadcn and next-themes convention).
- Update later by re-running the install with `--overwrite` (review the diff if you edited it). Changelog: https://beautiful-ui.dev/r/changelog.json

## Keyboard

| Keys | Action |
|---|---|
| Tab | Headers, then row checkboxes |
| Enter / Space | Sort, select |

## Performance

- Rows are absolutely placed; changes are top and opacity only.

## Responsive

- Scrolls sideways under its min width (900px).

## Motion inventory

| Interaction | What moves |
|---|---|
| Sort | Rows glide to their slots (460ms), 14ms apart |
| Filter | Filtered rows fade where they are (140ms); the rest glide up; the body's height follows (320ms) |
| Select all | The dash or check draws (220ms) |

## Accessibility contract (preserve when editing)
- role=table with columnheaders (aria-sort) and checkbox cells (aria-checked, mixed)
- Hidden rows are aria-hidden and unfocusable

## Install

```bash
npx shadcn@latest add @beautiful-ui-pro/data-table
```

Pro item: needs the `@beautiful-ui-pro` registry in `components.json` and `BEAUTIFUL_UI_TOKEN` in `.env.local` (https://beautiful-ui.dev/account). Setup: https://beautiful-ui.dev/docs/pro. Your components.json `style` picks the build: radix-*, new-york and default get Radix, base-* gets Base UI.

## Credits
- Built on shadcn/ui (https://ui.shadcn.com)

The notchset foundation (the tokens listed above, keyframes and motion levels) installs once with the first component; its CSS is public at https://beautiful-ui.dev/r/notchset-foundation.json.
