container.add(tableView);

thanks this helps me alot
but
need to update row to rowData
and
update the open value is not real update the property value in the rowData
so it keep add rows all the time
instead you can check that the title of the next row is the title of the first child if true so the subtable is opened

Hi, When I am click on 0 index Row, I am getting error "No row at this index".
