Tree, Grouping & Pivot

Hierarchical tree rows, group-by headers, footer aggregates, pivot cross-tabs, and responsive list view.

Each capability is opt-in via DataTableFeatures and its matching config struct.

  • Org charts and nested categories (TREE_DATA)
  • Group-by reports with subtotals (ROW_GROUPING, AGGREGATION)
  • Cross-tab analysis (PIVOTING)
  • Mobile-friendly card lists (LIST_VIEW)
  • Enable the relevant flag on features.
  • Pass get_tree_path, row_grouping, aggregation, pivot, or list_view props.
  • Read processed output via DataTableHandle::get_processed_dataset for downstream charts — see Charts Integration for the live binding pattern.
