使用TAB将焦点更改为JTable中的下一个组件

如果确实要这样做，则需要更改表操作映射的默认行为。

ActionMap am = table.getActionMap();am.put("selectPreviousColumnCell", new PreviousFocusHandler());    am.put("selectNextColumnCell", new NextFocusHandler());

然后，您需要执行一些操作来处理遍历

public class PreviousFocusHandler extends AbstractAction {    public void actionPerformed(ActionEvent evt) {        KeyboardFocusManager manager = KeyboardFocusManager.getCurrentKeyboardFocusManager();        manager.focusPreviousComponent();    }}public class NextFocusHandler extends AbstractAction {    public void actionPerformed(ActionEvent evt) {        KeyboardFocusManager manager = KeyboardFocusManager.getCurrentKeyboardFocusManager();        manager.focusNextComponent();    }}

另一种方法是禁用底层

Action

ActionMap am = table.getActionMap();am.get("selectPreviousColumnCell").setEnabled(false);am.get("selectNextColumnCell").setEnabled(false);

（尚未测试）

这种方法的好处是可以根据需要启用/禁用行为，而无需维护对旧行为的引用。
