Grouped subtable
AdaptedRoom for detail. Expanding a group opens a nested table with its own header and pagination.
Origin & adaptation notes
Combines the ReUI sub-table demo (an expandable row revealing a nested table) with the TukiGrowth GroupedDataGrid: each subtable keeps its own column header and pagination so a busy group never stretches the outer rows. Posts are synthetic.
Curated adaptation. Synthetic data only. No production APIs.
