그리드를 그리다 보면 기존 HTML을 이용해서 <thead>를 colspan, rowspan을 이용해서 컬럼을 그룹핑 해줄수 있었다. 그러나 extjs gridpanel에서 방법을 찾다가 해당 플러그인을 찾았다.
/**
* Plugin for grouped column headers
* @class Ext.ux.plugins.GroupHeaderGrid
* @extends Ext.util.Observable
* @author ?vind Neshaug
*
* Based on the code in this thread: http://extjs.com/forum/showthread.php?t=12677
* Thanks to JEBriggs for starting up the code and resizing code from Clayton
* Thanks to JorisA for the idea of making this a plugin instead of an extension.
*
* Supports infinte number of grouped header rows
* Supports header group spanning of rows
*
