本着自由共享的精神，把代码帖出来，同时大家也可以一起来测试以及添加新功能，请大家根据网友提出的问题，把自己修改好的版本都帖出来跟在下面，最后作为一款比较全面的表格软件。
Chgrid的简单功能介绍：
1：支持自定义排序
2：支持列宽度的拖放
3：支持自定义函数
4：支持分页
5：支持自动编号
6：多浏览器支持，支持ie6,ie7,ff,opera
7：div布局
已知问题：
1：由于使用的div布局，如果使用margin或者padding会改变定义的列宽度，所以目前文字只能居中或者靠左或靠右，不能使用padding控制位置
目前解决办法是可以在每个div里面再附加一个div，用这个div的margin属性来控制其位置。
2：内容在超出容器宽度的时候，拖动会有点小问题，。
怎样修改样式：
如果不改变风格，大家只要对如下部分代码调整就可以
Chgrid_column0{ width:20px;}
.Chgrid_column1{ width:100px;}
.Chgrid_column2{ width:80px;}
.Chgrid_column3{ width:120px;}
.Chgrid_column4{ width:100px;}
每多一列就再加一行比如.Chgrid_column5{ width:100px;}
注意：最后一列是不用定义宽度的，程序会自动调整

点击运行可以看到效果:

[Ctrl+A 全选提示:你可先修改部分代码,再按运行]

其它优秀的grid控件参考：
http://www.activewidgets.com
http://www.yui-ext.com/deploy/ext-1.0-alpha3/docs/
请千万不要把我这款控件跟它们比较，差距较大，不过我也有优势，使用起来比较简单，速度也快：）
本来想多加点数据，结果发现超过限制了，大家测试的时候自己多搞点数据测试其速度如何。
