</table><h2>What do I need to use this</h2><p>You need to download <a href="tablesort.js">tablesort.js</a> file and include it by adding
the following line to your document <code>HEAD</code>:</p><pre>
<script type="text/javascript" src="<a href="tablesort.js">tablesort.js</a>"></script>
</pre><p>You also need to organise your table into a table head and a table body and add the onclick
handler to the table tag. The table should look like this:</p><pre>
<table onclick="sortColumn(event)">
<thead>
<tr>...</tr>
...
</thead>
<tbody>
<tr>...</tr>
...
</tbody>
</table>
</pre><p>You don't need to include a special CSS file but I recommend that you do it anyway because that the
arrow should use the webdings font. Download <a href="tablesort.css">tablesort.css</a> and add the
following line to the <code>HEAD</code>:</p><pre>
<link rel="STYLESHEET" type="text/css" href="<a href="tablesort.css">tablesort.css</a>">
</pre><h2>What's next</h2><p>If you want I could convert this into a behavior for IE5 when it is released and I could also modify
it so that you don't have to add the onclick handler manually. <a href="../../contact.html#erik">Mail me</a>
if there is a demand for this.</p>

代码太长，时间太紧没看，针对这个排序可以先用split函数对
"-"拆分
然后生成一数字的二维数组
用sort方法进行排序在通过循环合回字符串
