showColumnHeaderContextMenu<T extends DataGridRow> function

void showColumnHeaderContextMenu<T extends DataGridRow>({ required BuildContext context, required Offset globalPosition, required DataGridColumn<T> column, required SortState sortState, required GroupState groupState, required DataGridController<T> controller, })

Shows the header right-click context menu for column at globalPosition: sort actions (if sortable), group/ungroup (if groupable), pin/unpin, and hide column.
