ListSelectionListener() on JComboBox in JTable

I have a ListSelectionListener to my JTable to pick up when given
cell with a JComboBox has changed.(in Col 0) When that occurs, the
rest of the data for that row needs to change to reflect the new
chosen value in the JComboBox, and the table redisplayed. I am trying
to use model..fireTableDataChanged() at the end to accomplish this,
without success.

Can anyone show me what I have misunderstood here about how to do
this? Clearly the task I am describing is nothing novel, and must have
been done a million times before, but for some reason I cannot find a
sample of how to accomplish it, and I'm not even sure I am on the
right path at all here. Thanks, RVince

table.getSelectionModel().addListSelectionListener(
                new ListSelectionListener() {

                    @Override
                    public void valueChanged(ListSelectionEvent arg0) {
                                             if(table.getSelectedColumn
()==0{
                                                  //do something that
changes the model's
                                                 // data vector based
on the value in the chosen
                                                 //cell's JComboBox
                                               ((DefaultTableModel)
table.getModel()).fireTableDataChanged();
                                          }
                                       }
                          }
 };
