public class Main extends JPanel {
  List<TableCellEditor> editors = new ArrayList<TableCellEditor>(3);

  public Main() {
    setLayout(new BorderLayout());

    String[] items1 = { "Red", "Blue", "Green" };
    JComboBox<String> comboBox1 = new JComboBox<String>(items1);
    DefaultCellEditor dce1 = new DefaultCellEditor(comboBox1);
    editors.add(dce1);

    String[] items2 = { "Circle", "Square", "Triangle" };
    JComboBox<String> comboBox2 = new JComboBox<String>(items2);
    DefaultCellEditor dce2 = new DefaultCellEditor(comboBox2);
    editors.add(dce2);
