Data

One very large table, understood at a glance.

50,000 developers, virtualized

Rank
Signals
Fifty thousand developers, virtualized. Resize, sort, and multi-select every row.

Drag a header edge to resize (double-click resets). Click a header to sort all 50,000 rows. Scroll right: the developer column stays pinned.

Filter the grid

Filters are a composition, not a grid feature. The DataGrid stays dumb — it renders the rows it is handed. A SearchField, a TagCombobox, and the applied FilterChips sit in the toolbar snippet and drive a `$derived` filtered array; the grid never knows a filter exists.

Summary
Toolbar filters compose over the grid: text + language narrow 50,000 rows to 7,065. The Summary column wraps to two lines.

Grid rules

Structure is visible

Row and cell hairlines always render. A table you have to squint at to see its own grid fails the non-technical reader first.

Direct manipulation

Columns resize by dragging, sort by clicking, and pin under horizontal scroll. The pulse green line marks the active resize; the chevron marks the active sort.

Honest scale

Rows virtualize, so fifty thousand render as thirty. Server-mode paging carries the same contract past what one payload can hold.

Cells carry meaning

Typed cells render design-system components, so provenance survives inside the grid: TypeScript Confirmed Top 3%

Charts

Charts are small with short explainers, never hero-sized, and divided bars replace donuts.

Comparison

Raw signals roll up to named capabilities before anyone reads them, so the UI speaks in velocity and craft, not metric names. Weights never render; evidence does.

Affinity chips read slate, not green: they state a relation to a reference developer, not a quality claim.

When to use what

DataGrid is the table for anything interactive or large. For short static tables in cards and reports, compose Table inside TableCard. TableShell is deprecated as of v4 — DataGrid absorbed its job.
