Freezing JTable Columns

Question

I am trying to freeze the first 3 columns in an editable Jtable. That is the easy part, I created 2 tables that share a table model. The tricky part is knowing which table is in focus or selected so I can work on the mouse/key events. I have tab working where i get to the end of one table and it goes into the next (most of the time). I am having trouble when I select a cell on a new row, the listSelectionEvent doesnt get a reference to the table, so I cant figure out which table is getting clicked.
Are there easier ways to get this to work or are there some stable off-the-shelf products that I could use?

please read http://download.oracle.com/javase/tutorial/uiswing/components/table.html#data , but this one works, too
  jTable1.setModel(new javax.swing.table.DefaultTableModel(new Object[][]{}, new String[]{"#", "Frequency", "Skip"}) {
            private static final long serialVersionUID = 1L;
            Class[] types = new Class[]{
                java.lang.String.class, java.lang.Integer.class,
                java.lang.Boolean.class
            boolean[] canEdit = new boolean[]{
                false, false, true
            @Override
            public Class getColumnClass(int columnIndex) {
                return types[columnIndex];
            @Override
            public boolean isCellEditable(int rowIndex, int columnIndex) {
                return canEdit[columnIndex];
        });
