FdcGridColumnGroup class
Visual definition for a column group rendered in the grid header.
Groups are intentionally lightweight: they only add a visual header band
above leaf columns that reference id through FdcGridColumn.groupId.
They do not change dataset schema, sorting, filtering, editing, summaries,
or row layout. Grouped columns cannot be pinned; pin actions are hidden for
them and programmatic pinning is ignored while the column belongs to a group.
