ObjectListView show Name of external Table instead of ID

[Yunus]

Hi,

I have a table let's call it "Table1" where the userId is stored. In another table, let's call it "Users" there is a UserName to this userId stored.

How can I show in Table1 the UserName instead of the userId?

I don't know where to search for. Any keyword or solution would be helpful.
Thanks
