使用FlexiGrid实现Extjs表格效果方法分享_jquery

近一段时间Extjs真的是风光无限好，只要是个做CRM/HRM之类的企业现在都在琢磨怎么在项目中用它，不过兄弟我可是不敢，原因很简单：太大/太笨/源码不好调试。但是对于Extjs漂亮的表格与功能的强大，实在是让我垂涎三尺，记得以前有个老外同志写过一个类似的Extjs的Jquery插件，所以就在Jquery的插件海洋中一顿海找，呵呵，还真让我找到了。看来还是我的Jquery好，小巧简单好像一部好的汽车引擎，我想要什么就可以自已DIY，真是方便。总体方案在网络传输上不超过80KB，速度比500KB大小的Extjs不知道要小上多少哪。。。

不过由于FlexiGrid在互联网上的大部分资料都是用PHP或者java写的，所以兄弟简单的对它进行了改制，也做了一个山寨版的Extjs表格实现，希望对大家有帮助。

基本使用：

1 基本使用是非常简单的，只需要加入Jquery库与FlexiGrid的JS即可以对表格进行格式化与美化.

2 加入需要格式化的表格即可

最简单的flexigrid表格-1

Col 1	Col 2	Col 3 is a long header name	Col 4
This is data 1 with overflowing content	This is data 2	This is data 3	This is data 4
This is data 1	This is data 2	This is data 3	This is data 4
This is data 1	This is data 2	This is data 3	This is data 4
This is data 1	This is data 2	This is data 3	This is data 4

为了增加FlexiGrid的基本使用效果，我们可以通过参数对其进行基本的调整

自定义表头

具体代码实现：

自定义折叠，自定义排序的实现

高级使用：

1 分页用到的存储过程

Create PROCEDURE [dbo].[spAll_ReturnRows]
(
@SQL nVARCHAR(4000),
@Page int,
@RecsPerPage int,
@ID VARCHAR(255),
@Sort VARCHAR(255)
)
AS
DECLARE @Str nVARCHAR(4000)
SET @Str='SELECT TOP '+
CAST(@RecsPerPage AS VARCHAR(20))+
' * FROM ('+@SQL+') T WHERE T.'+
@ID+
' NOT IN (SELECT TOP '+
CAST((@RecsPerPage*(@Page-1)) AS VARCHAR(20))+
' '+
@ID+
' FROM ('
+@SQL+
') T9 ORDER BY '+
@Sort+
') ORDER BY '+
@Sort
PRINT @Str
EXEC sp_ExecuteSql @Str
