Hi Paul,

I'm going to have to approach this one step at a time, only becouse
constructing a JTable appears to be no small feat.
So I thought to start out by creating a small practice example that makes
all cells in the table of type JLabel.  According to what I've read the
DefaultTableCellRenderer extends JLabel, so it would appear I won't have to
make my own.

I threw together the following program in an attempt to use
DefaultTableCellRenderer and have all the cells of the table un-editable
(that being the case with JLabel).  However, it didn't perform as I had
hoped.  When I ran it, each cell was still editable! Perhaps you can explain
why that is, and what I need to do to fix it?
