【jquery模仿net控件】初步GridView模型实现，及其简单应用

最近日子不好过，主要原因是要毕业了，学校那边的毕业论文让人很头痛，就跟写八股文似的，个人非常头疼并且厌恨这种
对我无意义的东西，哎！！！体制啊，既然无法改变，何不将之做好呢！！！对，于是我还是不想写论文，拖着吧，到哪天确实
拖不下去了再说；加之公司项目也非常紧，又要写论文，虽说没写，心里就是一个不舒服啊！！！所以平时抽了点时间模拟了下
gridview，个人是菜鸟自不必多说，但是这几个月来，模拟写着写着感觉学到了不少东西哟！！！
算了....扯远了，进入正文。
过程中需要类似gridview的功能，索性也就写了一下，思路与datalist差距不大。
因为马上要写论文了，而且是不完全版本这里就不画图什么的了，以后发完整版本再说吧：
① 鼠标滑动时变色事件
② 点击大类选取小类事件
③ 点击获取时候全部获取事件
④ 当然，不能忘了行绑定事件，初期只是绑定了大类，小类根据大类id作出的加载
详细请看下个版本吧，此版本欢迎拍砖

前期工作
之前主要模拟了一次datalist，基本上以它为基础将igoogle功能完全实现，并且应用到项目中去了，控件不好，但也不是完全没有意义，过程中需要类似gridview的功能，索性也就写了一下，思路与datalist差距不大。
因为马上要写论文了，而且是不完全版本这里就不画图什么的了，以后发完整版本再说吧：
效果图
简单说明
该简单应用也是我第一次做测试，有一下几个事件：① 鼠标滑动时变色事件
② 点击大类选取小类事件
③ 点击获取时候全部获取事件
④ 当然，不能忘了行绑定事件，初期只是绑定了大类，小类根据大类id作出的加载

控件生成流程：
1 先初始化表格每列的【列头】以及【body信息】，最好可指定列id，用于后期检索
2 赋予控件二维数据（但控件字段最好可支持多维数据获取）
3 初始化外围table，并赋予其属性样式,最外层结束
4 根据二维数据依次初始化每行数据，【其实可在此处初始化表头，因为若是没有数据表头将不初始化】
5 每行获得其数据源，先形成tr，然后将数据源直接赋予单元行进行初始化
6 单元化格式化单元模板，生成html标签
