Some tables have related tables that are down on the same tab screen.
For example Country and Serie(Set). To manipulate (insert, exclude, edit) a
related record, just click on the main table (in this example Country), to select
the record you want to see the related ones. Then click on the related record
on the other grid, and do the same operation to Insert/Exclude/Edit the record,
as it were a normal table.
