迷茫中.....请问SWING开发中
如何在JTABLE中部署JPOPUPMENU？
需求为：
JTABLE为显示数据库查询结果的表
当用鼠标右键选中JTABLE中的一行时，弹出JPOPUPMENU
类似JB中JDBTABLE所实现的效果

现在我遇到的问题是：JPOPUPMENU不能在JTABLE中显示

JPOPUPMENU.SHOW(E.GETCOMPONENT,E.GETX(),E.GETY())
是不是JTABLE不属于COMPONENT？？
我是菜鸟，不要取笑我，各位高手请给点指点吧，谢谢

代码如下,个人认为貌似没有什么语法错误吧?
我还特地获取了鼠标点击时的坐标..............
运行结果:
JFRAME全屏显示时,不管点在哪里,菜单都不出现
JFRAME不是全屏显示时,鼠标点击在JTABLE的最右边一部分区域有显示,
不解................迷茫中.............高手赐教啊
