# Performance Table

> A wide analytics grid for campaign or product metrics: grouped two-tier headers, a pinned name column, expandable child rows and a sticky totals row. Jump-to pills and a draggable minimap scrub across column groups. Heatmap tints cells by how good they are, Compare shows change from the last period, and headers light their column.

## Install

One-time setup (needs a subscription):

1. Add the registry to the project's `components.json`: `{"@assembli":{"url":"https://www.assembli.design/r/{name}.json","headers":{"Authorization":"Bearer ${ASSEMBLI_API_KEY}"}}}` (merge into `"registries"`).
2. Put an API key from https://www.assembli.design/account in `.env.local` as `ASSEMBLI_API_KEY=asm_…`.

Then install with the shadcn CLI (writes `components/performance-table/performance-table.tsx` and installs dependencies):

```bash
npx shadcn@latest add @assembli/performance-table
```

Registry item JSON: https://www.assembli.design/r/performance-table.json (send `Authorization: Bearer <api key>`)
