JTableが配置されたJScrollPaneのBorderを変更する

JScrollPane scroll = new JScrollPane(table);
// scroll.setBorder(new BorderUIResource(BorderFactory.createLineBorder(Color.BLUE)));
String key = "Table.scrollPaneBorder";
JCheckBox check = new JCheckBox(key, Objects.nonNull(UIManager.getBorder(key))) {
  @Override public void updateUI() {
    super.updateUI();
    boolean b = Objects.nonNull(UIManager.getLookAndFeelDefaults().getBorder(key));
    updateTableScrollPane(scroll, key, b);
    setSelected(b);
  }
};
check.addActionListener(e -> {
  boolean b = ((JCheckBox) e.getSource()).isSelected();
  updateTableScrollPane(scroll, key, b);
});
// ...
public static void updateTableScrollPane(Component scroll, String key, boolean lnf) {
  Border border;
  if (lnf) {
    border = UIManager.getLookAndFeelDefaults().getBorder(key);
  } else {
    border = new BorderUIResource(BorderFactory.createEmptyBorder());
  }
  UIManager.put(key, border);
  SwingUtilities.updateComponentTreeUI(scroll);
}
