Спасибо, camickr!
Поэтому, когда я изменяю код, следуя вашему совету, это работает.
Вот полный пример:
package TableTest;

Я получил привязки клавиш к действиям из ActionMap и InputMap JTable. Я попытался добавить небольшой метод
// print a String representation of each KeyStroke from the InputMap
private void printActions(JTable table) {
InputMap input = table.getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT);
if (input != null && input.allKeys() != null) {
for (KeyStroke key : input.allKeys()) {
if (key != null) {
printKeyStroke(key);
printActionName(input, key);
}
}
}
}
// build the String represantation
private void printKeyStroke(KeyStroke key) {
StringBuilder tk = new StringBuilder("[");
int modifiers = key.getModifiers();
if ((modifiers & InputEvent.SHIFT_DOWN_MASK) != 0)
tk.append("shift+");
if ((modifiers & InputEvent.CTRL_DOWN_MASK) != 0)
tk.append("ctrl+");
if ((modifiers & InputEvent.META_DOWN_MASK) != 0)
tk.append("cmd+");
if ((modifiers & InputEvent.ALT_DOWN_MASK) != 0)
tk.append("alt+");
tk.append("'");
tk.append(KeyEvent.getKeyText(key.getKeyCode()));
tk.append("'=");
tk.append("keycode=");
tk.append(key.getKeyCode());
tk.append("]");
System.out.print(tk.toString());
}
private void printActionName(InputMap input, KeyStroke key) {
System.out.print(": ");
Object string = input.get(key);
if (string != null && string instanceof String)
System.out.println(string.toString());
}
