Whoops, I didn't notice until Florian's message that you *did* post
this code. If your table columns don't have the right identifiers,
tableView:objectValueForTableColumn:row: returns nil, which results in
an empty cell. So, to echo Quincy's question, what exactly "does not
work"? Is your table displaying *empty* rows, or *no* rows? Is it
possible your table columns aren't named what you think they are?
