Swing Jtble 排序后，表格数据无法刷新

（源代码文件Test.java在最后已附上）
操作描述：
1.添加 -> 刷新
2.点击表头进行排序
3.清空 -> 刷新
4.刷新按钮失效，会报错，如何解决？（如果不点击表头排序，则功能正常）

这里有解释，关于JTable模型机制的

原因不知道

哥哥啊，你这代码完全netbeans拖出来的，都不知道jtable的基本概念，数据直接加到jtable的Model里，不用你管理界面刷新，table有对model的监听，会自己刷

这个情况我遇到过，我的解决方法是：排序之前把jtable内容设置为空，再调用排序，然后调用显示的。希望你能解决你的问题
