给后来者：的确是4楼所说的，将Jtable中写死了，后来的数据如果缺少，比如只有3行，但Jtable在初次设置model时有4行，则会报这个异常。

解决方法：就是在放入不足4行的新数据时，给Jtable从新new Jtable()，再给model就可以解决。记得在把新的table放到panel或者需要的地方上。不见得最好，但可以解决。

[Quote=引用 4 楼 yanhan0615 的回复:]
你构造的JTable是一个4列的表，所以插入的时候应该这样：

Java code
DefaultTableModel tableModel = (DefaultTableModel) MainFrame.getInstance().jTable.getModel();
tableModel.insertRow(0, new String[]{"a1","a2","a3","a4"});
[/Quote]
没用，照样报错
