Creating a dynamic JTable wit JComboBox

Question

I am trying to create a dynamic Jtable such that the first column is editable and the other columns contain JComboBoxes that contain as items all the elements of the first column. I can build the table, but I want to make it dynamic so that when the contents of a cell in the first column are changed, all the combo boxes are updated to reflect this change. In general, what is the best way to do this?

        final JComboBox jcb = new JComboBox();
        data.addTableModelListener(new TableModelListener() {

                HashSet s = new HashSet();
                for (int i = 0; i < data.getRowCount(); i++) {
                    s.add(data.getValueAt(i,0));
                jcb.setModel(new DefaultComboBoxModel(new Vector(s)));
        TableCellEditor tce = new DefaultCellEditor(jcb);
        JTable jt = new JTable(data);
        for (int i = 1; i < data.getColumnCount(); i++) {
            jt.getColumnModel().getColumn(i).setCellEditor(tce);
        javax.swing.JFrame f = new javax.swing.JFrame();
        f.setDefaultCloseOperation(f.EXIT_ON_CLOSE);
        f.getContentPane().add(new JScrollPane(jt));
        f.pack();
        f.setVisible(true);
