我是靠谱客的博主执着水蜜桃，最近开发中收集的这篇文章主要介绍javascript之dhDataGrid Ver2.0.0代码，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

针对dhDataGrid的前一版本Ver1.0.0而做的更新！

1、标题栏、左边边栏固定方式更新，取消expression方式；

2、排序方式更新，同时支持数字、字符、日期、数字字符混合、中文汉字的排序；

3、支持换肤，您可以自己定制该控件样式；

4、预留[双击]、[右键]功能；

5、支持IE、FF；

CSS：

/*dhdatagrid 大块样式*/
#dhdatagrid {position:relative;width:500px;height:200px;background:white;margin:0px;padding:0px;overflow:hidden;border:1px inset;-moz-user-select:none;}
