javascript-表格排序(降序/反序)实现介绍(附图)

知识点：

Array方法：

sort:降序

reverse:反序

效果：
 
代码：

<style> 
*{ 
margin: 0; 
padding: 0; 
} 
#tableSort{ 
line-height: 22px; 
background: #ccc; 
} 
#tableSort thead, 
#tableSort tfoot{

color: #fff; 
font-size: 14px; 
} 
#tableSort thead a, 
#tableSort tfoot a{

总结：

完成了基本功能，对于联合排序没有实现。后期会慢慢加入，有兴趣的可以把代码放到html页面，运行查看效果。
