Swing完整实例JTree右键菜单可拖拽+JTable可翻页列中含有按钮隐藏列
首先来看一下展示界面，JTree的特点有：
节点可拖拽，根据输入生成目录，右键有菜单，点击触发事件等
JTable的特点有：
含有隐藏列，可以进行翻页，列中含有下载按钮等
在来看一下代码吧，基本代码由Eclipse上的WindowBuilder进行拖拽式产生的，所以看起来有点乱，不过没事
在使用WindowBuilder的时候要画JTree和JTable时要注意，这两个有几个共同点，必须放到JScrollPanel中，因为这两个控件的内容长度会发生突然变化，所以要使用JScrollPanel。
BTW：
如果要使用WindowBuidler，除了在Eclipse上安装插件，最方便的方法是直接下载含有该插件的Eclipse版本：
