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{
background: #066;
color: #fff;
font-size: 14px;
}
#tableSort thead a,
#tableSort tfoot a{
color: #fff;
}
#tableSort tfoot{
background: #069;
}
#tableSort tbody td{
background: #fff;
padding: 3px 5px;
font-size: 12px;
}
</style>

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。
