But when I select the default value, the combobox will not disappear.
So, how can I disappear the combobox when user select the default value

public class TableComboBoxByRow extends JFrame
     ArrayList editors = new ArrayList(3);
     public TableComboBoxByRow()
          // Create the editors to be used for each row
          String[] items1 = { "Red", "Blue", "Green" };
          JComboBox comboBox1 = new JComboBox( items1 );
          DefaultCellEditor dce1 = new DefaultCellEditor( comboBox1 );
          editors.add( dce1 );
          String[] items2 = { "Circle", "Square", "Triangle" };
          JComboBox comboBox2 = new JComboBox( items2 );
          DefaultCellEditor dce2 = new DefaultCellEditor( comboBox2 );
          editors.add( dce2 );
          String[] items3 = { "Apple", "Orange", "Banana" };
          JComboBox comboBox3 = new JComboBox( items3 );
          DefaultCellEditor dce3 = new DefaultCellEditor( comboBox3 );
          editors.add( dce3 );
          //  Create the table with default data
          Object[][] data =
               {"Color", "Red"},
               {"Shape", "Square"},
               {"Fruit", "Banana"},
               {"Plain", "Text"}
          String[] columnNames = {"Type","Value"};
          DefaultTableModel model = new DefaultTableModel(data, columnNames);
          JTable table = new JTable(model)
               //  Determine editor to be used by row
               public TableCellEditor getCellEditor(int row, int column)
                    int modelColumn = convertColumnIndexToModel( column );
                    if (modelColumn == 1 && row < 3)
                         return (TableCellEditor)editors.get(row);
                    else
                         return super.getCellEditor(row, column);
          JScrollPane scrollPane = new JScrollPane( table );
          getContentPane().add( scrollPane );
     public static void main(String[] args)
          TableComboBoxByRow frame = new TableComboBoxByRow();
          frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
          frame.pack();
          frame.setVisible(true);
}

The following modification seems to work...
          final JTable table = new JTable(model)
          getContentPane().add( scrollPane );
          PopupMenuListener stopEditing = new PopupMenuListener() {
               public void popupMenuWillBecomeVisible( PopupMenuEvent e ) {}
               public void popupMenuWillBecomeInvisible( PopupMenuEvent e ) {
                    TableCellEditor editor = table.getCellEditor();
                    if ( editor != null )
                         editor.stopCellEditing();
               public void popupMenuCanceled( PopupMenuEvent e ) {}
          comboBox1.addPopupMenuListener( stopEditing );
          comboBox2.addPopupMenuListener( stopEditing );
          comboBox3.addPopupMenuListener( stopEditing );          
     }
