I've been working on the program this morning and I've figured *some*
things out.  The progress bar is now updatnig.  The problem is that,
if I have multiple rows, ALL of their progress bars are updating when
I only want one to be updating (the one that is currently
processing).  It seems as though every cell holds the same
ProgressBarRenderer and I'm not sure how to give each row its own
renderer (especially because the example I was using to help me figure
this out doesn't seem to do that).

Below is the initialization for the JTable.  I update the table model
(which extends DefaultTableModel) via the Observer pattern.  (The work
is being done in other classes and the progress bar is being updated
based on that work.  I'm not even sure if this is the best way to do
it, but that's not my main problem.)

private JTable getRunningTable() {
  if (runningTable == null) {
    runningTable = new JTable(runTableModel);

    // TODO set column widths

    // don't allow dragging of columns
    runningTable.getTableHeader().setReorderingAllowed(false);

    // setup selection process
 
runningTable.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);

    // set column renderer for a JProgressBar
    TableColumn col =
runningTable.getColumnModel().getColumn(RunView.PROGRESS_BAR_COLUMN);
    col.setCellRenderer(new ProgressBarRenderer());
  }
  return runningTable;
}


Thanks for your help.
