响应式表格之固定表头的实现

数据展示时,表头的固定,可以有更好的可读性。

一、实现方式:
1、定义2个表格,一个absolute固定

<div class="table1-wapper">
   <table width="100%" cellpadding="0" cellspacing="0" id="table1">
      <tr><th><div>序号</div></th><th><div>股票名称</div></th>...</tr>
       <tr>...</tr>
  </table>
</div>
 <div class="fixed-table1-wapper">
  <table width="100%" cellpadding="0" cellspacing="0" id="fixed-table1">
 </table>
</div>

2、表1<th>复制,并插入表2

var th_new=$("#table1 tr").eq(0).clone();
$("#fixed-table1").append(th_new);

3、resize()方法,实时获取表1各列<th>宽度

function trResize(){
	$("#fixed-table1 th").each(function(){
	var num=$(this).index();
	var th_width=$("#table1 th").eq(num).width();
	$(this).css("width",th_width+"px");
	});
}

4、页面过小时,表格滚动带表头滚动

$(".table1-wapper").scroll(function(){
	var scroll=-$(this).scrollLeft()
	$(".fixed-table1-wapper").css("left",scroll+"px");
});

二、注意细节:

1、宽度自适应、去除单元格间隙:
<table width="100%" cellpadding="0" cellspacing="0" ></table>

2、表格线:
直接<td>添加border,会出现边线重合;添加属性:border-collapse: collapse;

3、td宽度:
控制第一行宽度即可 <td width="70"></td>  /  <td width="20%"></td>

4、奇偶行颜色不同:
css: #table1 tr:nth-child(2n){background-color:#ccc;} ie7兼容性问题
jquery: $("#table1 tr:even").css("background-color","#ccc");

以下为完整代码:

<!doctype html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>表格整理</title>
<link rel="stylesheet" type="text/css" href="css/basic.css">
<script type="text/javascript" src="js/jquery-1.8.3.min.js"></script>
<style type="text/css">

.table-wapper{100%;margin:30px auto;font-size:16px;position:relative;overflow:hidden;}
.table1-wapper{height:200px;overflow-y:auto;}
.table-wapper table{border:1px solid #f00;line-height:2;border-collapse: collapse;white-space:nowrap;}
.table-wapper th{font-size:18px;font-weight:normal;background-color:#dbdbdb;}
.table-wapper td{text-align:center;border:1px solid #f00;}
.fixed-table1-wapper{position:absolute;top:0px;left:0px;background-color:#dbdbdb;}
/*#table1 tr:nth-child(2n){background-color:#ccc;}*/
</style>
