JTableで行の追加、削除アニメーション

private void testCreateActionPerformed(ActionEvent e) {
  model.addTest(new Test("New name", ""));
  (new Timer(DELAY, new ActionListener() {
    int i = table.convertRowIndexToView(model.getRowCount() - 1);
    int h = START_HEIGHT;
    @Override public void actionPerformed(ActionEvent e) {
      if (h < END_HEIGHT) {
        table.setRowHeight(i, h++);
      } else {
        ((Timer) e.getSource()).stop();
      }
    }
  })).start();
}

private void deleteActionPerformed(ActionEvent evt) {
  final int[] selection = table.getSelectedRows();

    return;
  }
  (new Timer(DELAY, new ActionListener() {

    @Override public void actionPerformed(ActionEvent e) {
      h--;
