表格隔行显示不同背景颜色，表格奇数行和偶数行交替显示不同的背景颜色。
一、纯CSS3实现表格隔行变色
关键CSS代码介绍
table tr:nth-child(odd){background:#F4F4F4;}
table td:nth-child(even){color:#C00;}
table tr:nth-child(5){background:#73B1E0;color:#FFF;}
二、jquery实现表格奇数行和偶数行交替显示不同的背景颜色
<html>
<head>
<script type="text/javascript" src="http://apps.bdimg.com/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript">
$(function(){
$("tr:even").css("background","#090");
$("tr:odd").css("background","red");
})
</script>
</head>
<body>
<table width="400" >
<tr>
<td>www.125jz.com</td>
</tr>
<tr>
<td>网页设计教程</td>
</tr>
<tr>
<td>www.125jz.com</td>
</tr>
<tr>
<td>网页设计教程</td>
</tr>
</table>
</body>
</html>
三、jquery实现表格隔行变色、鼠标悬停高亮
<!doctype html>
<html><head>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<title>表格隔行变色_CSS实现鼠标悬停高亮</title>
<meta name="keywords" content="" />
<meta name="description" content="" />
<script type="text/javascript" src="http://apps.bdimg.com/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript">
$(function(){
//通过jQuery控制表格隔行换色，并鼠标悬停变色
$('tr:even:gt(0)').addClass('tr_even'); //默认偶数行背景色，无视标题行用:gt(0)
$('tr:odd').addClass('tr_odd'); //默认奇数数行背景色
});
</script>
<style type="text/css">
.headCls{background-color:#ccc;} /* 标题背景色 */
.tr_even{background-color:#EBF8FF} /* 偶数行背景色 */
.tr_odd{background-color:#DDECF3} /* 奇数行背景色 */
.tr_even:hover,.tr_odd:hover{background-color:red;} /* 通过CSS实现鼠标悬停高亮色 */
</style>
</head>
<body>
<table border="1" width="100%" cellspacing="0" cellpadding="0">
<tr class="headCls">
<th>CSS实现鼠标悬停高亮</th>
<th>CSS实现鼠标悬停高亮</th>
</tr>
<tr>
<td>data1_1</td>
<td>data1_2</td>
</tr>
<tr>
<td>data2_1</td>
<td>data2_2</td>
</tr>
<tr>
<td>data3_1</td>
<td>data3_2</td>
</tr>
<tr>
<td>data4_1</td>
<td>data4_2</td>
</tr>
<tr>
<td>data5_1</td>
<td>data5_2</td>
</tr>
</table>
</body>
