In the spirit of free sharing, you can post the code and test and add new functions together. Please refer to the questions raised by netizens, post all the modified versions below and use them as a comprehensive table software.
A Brief Introduction to Chgrid:
1: supports custom sorting
2: supports drag and drop of column width
3: Support for custom functions
4: pagination is supported.
5: Supports automatic numbering
6: supports multiple browsers, including ie6, ie7, ff, and opera.
7: div Layout

Known issues:
1: Because the div layout is used, if you use margin or padding, the defined column width will be changed. Currently, the text can only be centered or left or right, and the position cannot be controlled using padding.
Currently, the solution is to append a div in each div and use the margin attribute of this div to control its position.
2: When the content exceeds the container width, dragging will be a little problem ,.

How to modify a style:
If you do not change the style, you only need to adjust the following part of the code.
Chgrid_column0 {width: 20px ;}
. Chgrid_column1 {width: 100px ;}
. Chgrid_column2 {width: 80px ;}
. Chgrid_column3 {width: 120px ;}
. Chgrid_column4 {width: 100px ;}
Add a row for each column, for example,. Chgrid_column5 {width: 100px ;}
Note: The last column does not need to define the width, and the program will automatically adjust it.Xmlns = "http://www.w3.org/1999/xhtml">
