Why are the contents of this table not being shown?

The code below was entirely generated by a visual GUI builder (*).
This is the way it looks like, in design mode:

My problem is that the cell contents are not being displayed at run
time for some reason.

What I am trying to do is port this NetBeans-specific module to
standard code and jar:

TIA!,
