grouping

This skill builds on core, table-features, and client-vs-server. Grouping creates row structure and the renderer chooses grouped-cell UI. Load the separate aggregation skill when grouped rows should also calculate values.

Setup

import {
  columnGroupingFeature,
  createGroupedRowModel,
  tableFeatures,
} from '@tanstack/table-core'

export const features = tableFeatures({
  columnGroupingFeature,
  groupedRowModel: createGroupedRowModel(),
})
