J表。删除行。消耗事件以不再进一步分派

我需要按删除键从 JTable 中删除行。所以用例非常简单，用户选择一些行，按删除键，行就会被删除。代码也很简单：

DefaultTableModel tableModel = (DefaultTableModel) table.getModel();
    int[] selectedRows = table.getSelectedRows();
    for (int i = selectedRows.length - 1; i > -1; i--) {
        tableModel.removeRow(selectedRows[i]);
    }

问题是，删除完成后，我们会听到一声嘟嘟声（我在 Windows 上，是典型的 Windows 嘟嘟声），就像在空文本框中按删除键时（或者插入符号位于文本末尾时一样）。文本）。 我正在发生的事情是，按键被进一步分派到显示单元格文本内容的文本组件（删除的单元格之后的第一个单元格）。由于点前面没有字符，DefaultEditorKit$DeleteNextCharAction#actionPerformed 方法会发出蜂鸣声。 作为黑客，我修改了侦听​​器中的事件：

e.setKeyCode(KeyEvent.VK_SHIFT) // see JTable#processKeyBinding

该事件不会进一步转发，蜂鸣声是否消失，但我认为这是一个糟糕的解决方案，并且有一个更好的解决方案。但哪个是更​​好的解决方案呢？

• 您删除行的核心是错误的，必须从最大索引开始，否则删除未选定的行，
