一个Javascript的类库，用于table内容排序。使用很方便，不用每次都去调用数据库了。
特别适合多表查询的排序。加上<tbody>的style.display切换，也可以实现分页。
效果演示
用法:
1.添加JS
<SCRIPTsrc="sorttable.js"type="text/javascript"></SCRIPT>
2.添加TABLE,注意的是：一定要有ID,class为"sortable"
<tableclass="sortable"id="mytable">
OK,可以了，简单的吧
如果觉得太单调，自己加点CSS吧，官方给出了改HEAD的CSS


table.sortablea.sortheader{
background-color:#eee;
color:#666666;
font-weight:bold;
text-decoration:none;
display:block;
}
table.sortablespan.sortarrow{
color:black;
text-decoration:none;
}

复制代码 代码如下:
addEvent(window,"load",sortables_init);

varSORT_COLUMN_INDEX;
