jQuery table column width can be changed by dragging and is compatible with firfox_jquery

This demo uses the jQuery package to realize the drag-and-drop function of table column width and realize the re-layout when the page is reset. Use jQuery to facilitate function calls. After adding an id to the table to be processed, you can directly call $("#id").movedTh() to facilitate the implementation and modify the compatibility of firfox.

The code is as follows: 

<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=gb2312"> 
<mce:script type="text/javascript" src="jquery-1.3.2.min.js" mce_src="jquery-1.3.2.min.js"></mce:script> 
<mce:style><!-- 
.resizeDivClass 
{ 
position:absolute; 
background-color:gray; 
width:2px; 
height:15px; 
z-index:1px; 
display: block; 
cursor:e-resize 
} 
.td1 { 
font-size: 12px; 
white-space:nowrap; 
color:#0000ff; 
} 
--></mce:style><style mce_bogus="1">.resizeDivClass
