Expand description
A virtualized grid over a caller-flattened hierarchy.
TreeGrid does not discover topology, flatten nodes, or own expansion and
selection. The caller supplies visible rows in reading order and receives
selection and expansion intents. Only materialized viewport rows publish
the ARIA hierarchy TreeGrid > Row > GridCell.
Columns are fixed or flexible within the available width. There is no horizontal scrolling or frozen-column behavior.
