Ext3.x版本锁定列和多表头的插件,BUG修复版
Ext3.x版本的锁定列和多表头都是通过插件实现，但是这两个插件不能一起工作，而实际上这样的业务也是存在的，即在多表头的情况下也需要锁定列。
在Ext的论坛上有很多这样的需求，都没有一个解决方案，除了一个需要收费的（150没有），而且联系起来也麻烦。后面决定自己做一个。
效果如下图：

效果图:
写在后面的话: 左右对不齐的BUG修复方法,使用jQuery暴力修改,因此需要引入jQuery.js.
从CSDN找到了多表头锁定控件,到修改BUG,再到生产中实际运用.关键还是源码源码源码.
这个控件还剩下一个小尾巴BUG,就是暂时还不支持checkboxSelectionModel.
本篇博客将会继续更新.
