YUI2.8 实现TabView和DataTable的结合使用
实现的功能：使用YUI2.8 实现TabView和DataTable的结合使用，在TabView添加两个tab，每个tab都是datatable，datatable的数据是从后台动态获取数据，同时实现分页的功能。
简述我的调试过程，先做好一个datatable，保证单个datatable能正确地显示，且分页功能没有问题，然后做一个简单的tabview，也同样保证没有问题之后；再完成最后一步的整合功能。
主要的时间是花在写JS脚本和调试上，做事还是一步一步来，遇到问题不要紧张，仔细想想是自己什么地方写错了，或者那个JS CSS文件没有引对。
我也是YUI的新手，希望有人能和我互相交流。
