请教：JTable中removeRow的问题

[snbj_111]

我在JTable中用列的方式生成”cancel“的JButton按钮,目的是：每次双击"cancel"按钮，则removerow当前行（stateModel.removeRow(currentRow);）。
问题是：假如JTable中有三条记录，当我从上到下的顺序cancel掉JTable的每一行时则正常；但是当我先cancel掉最后一行后（不会出现异常），再cancel其它行时则会出现异常，

具体需要查看代码
不过给格例子

删除最后行以后currentRow应该是新的一行，0或者1，但现在还是=2，所以就出现越界了，错误现象应该是这样

你从上到下删除没有问题而先删除最后一行后，再删其他的数据时抛出异常
我认为删除操作是根据JTable的行递增删除~！~
要解决这个问题~~你不妨在删除时给删除方法一个参数~~使它从第一条记录删除~~
或者是加一条判断语句~~~如果到最后就转到第一条记录。

JTable的editor与行删除的java.lang.ArrayIndexOutOfBoundsException错误（by lie2believe）
在JTable中，如果单元格设成editor,而且更改了editor值的话，如果恰好处在最后一行，如果这时候把该行删除，去点其它行的editor的话，会出现java.lang.ArrayIndexOutOfBoundsException的错误！

＝＝为什么呢？
因为JTable中的editor值变化当时，并不会引发JTable的变化，只有焦点不在该editor时，才会有消息通知JTable，会生成一个javax.swing.AbstractCellEditor.fireEditingStopped消息，继而引发javax.swing.JTable.editingStopped事件，但事件发生时，该行已经被删除了，因而出现上面的错误。

＝＝怎样解决呢？
在editor的相应事件中执行editingStopped或者editingCanceled即可。如在JCheckBox的editor中，执行：
public void actionPerformed(ActionEvent e) {
super.actionPerformed(e);
JCheckBox box = (JCheckBox)e.getSource();
ChangeEvent ce = new ChangeEvent(box);
self.editingStopped(ce);
}
