This skill builds on core, table-features, and client-vs-server. Expansion controls row-tree inclusion; the renderer owns disclosure controls and detail panels.

Setup

import {
  createExpandedRowModel,
  rowExpandingFeature,
  tableFeatures,
} from '@tanstack/table-core'

type Node = { id: string; children?: [] }
  features = ({
  rowExpandingFeature,
  : (),
})
  options = { :  row. }
