本文实例讲述了JS实现的点击表头排序功能。分享给大家供大家参考，具体如下：

运行效果：

1、index.html文件：

<html>

<body>
<table id="MyHeadTab" cellspacing="0" onclick="sortColumn(event)">

 <tr>
  <td>String</td>
  <td title="CaseInsensitiveString">String</td>
  <td>Number</td>

  <tbody>
 <tr>
  <td>apple</td>
  <td>Strawberry</td>
  <td>45</td>

2、tablesort.js文件：

}

3、tablesort.css文件：

tr  {background: window;}
td  {color: windowtext; font: menu; padding: 1px; padding-left: 5px; padding-right: 5px;
  border-right: 1px solid buttonshadow;
  border-bottom: 1px solid buttonshadow;
}
table {border-top: 1px solid buttonshadow;
  border-left: 1px solid buttonshadow;
  border-right: 1px solid buttonhighlight;
  border-bottom: 1px solid buttonhighlight;
   }
thead td {background: buttonface; font: menu; border: 1px outset white;
  padding-top: 0; padding: bottom: 0;
  border-top: 1px solid buttonhighlight;
  border-left: 1px solid buttonhighlight;
  border-right: 1px solid buttonshadow;
  border-bottom: 1px solid buttonshadow;
  height: 16px;
}
thead .arrow{font-family: webdings; color: black; padding: 0; font-size: 10px;
  height: 11px; width: 10px; overflow: hidden;
  margin-bottom: 5; margin-top: -3; padding: 0; padding-top: 0; padding-bottom: 2;}
  /*nice vertical positioning :-) */
