JTable help

I'm working on a derby embedded app and I want to use JTable to
display the results. I made a custom AbstractModel, but when there is
more than one row in the results the first row result is repeated for
the number of rows in the result but the other results are not
displayed. I was able to get it to output correctly to the console
but not the gui. I am stuck and can't figure out where I went wrong.
Can someone help me?

I think the problem is in here, but I am not sure I can post the other
parts of the program if necessary. Thanks in advance...
