这里是用JS实现的：http://www.cnblogs.com/xuyiqing/p/8376312.html
接下来利用上一篇提到的选择器利用jQuery实现：
发现原来多行代码这里只需要两行：
<!DOCTYPE html>
<html> <head>
<meta charset="UTF-8">
<title>表格隔行换色</title>
<script type="text/javascript" src="js/jquery-1.8.3.js" ></script>
<script>
$(function(){
$("tbody>tr:even").css("background-color","pink");
$("tbody>tr:odd").css("background-color","aqua");
});
</script> <style> </style> </head> <body>
<table border="1" width="500" height="50" align="center" id="tbl">
<thead>
<tr>
<th>编号</th>
<th>姓名</th>
<th>年龄</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>张三</td>
<td>22</td>
</tr>
<tr>
<td>2</td>
<td>李四</td>
<td>25</td>
</tr>
<tr>
<td>3</td>
<td>王五</td>
<td>27</td>
</tr>
<tr>
<td>4</td>
<td>小明</td>
<td>29</td>
</tr>
<tr>
<td>5</td>
<td>小红</td>
<td>30</td>
</tr>
<tr>
<td>6</td>
<td>小刚</td>
<td>20</td>
</tr>
</tbody>
</table>
</body> </html>
更好的方式是直接为标签添加类：
<!DOCTYPE html>
<html> <head>
<meta charset="UTF-8">
<title>表格隔行换色</title>
<script type="text/javascript" src="js/jquery-1.8.3.js" ></script>
<script>
$(function(){
$("tbody>tr:even").addClass("even");
$("tbody>tr:odd").addClass("odd");
});
</script> <style>
.even{
background-color: pink;
}
.odd{
background-color: aqua;
}
</style> </head> <body>
<table border="1" width="500" height="50" align="center" id="tbl">
<thead>
<tr>
<th>编号</th>
<th>姓名</th>
<th>年龄</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>张三</td>
<td>22</td>
</tr>
<tr>
<td>2</td>
<td>李四</td>
<td>25</td>
</tr>
<tr>
<td>3</td>
<td>王五</td>
<td>27</td>
</tr>
<tr>
<td>4</td>
<td>小明</td>
<td>29</td>
</tr>
<tr>
<td>5</td>
<td>小红</td>
<td>30</td>
</tr>
<tr>
<td>6</td>
<td>小刚</td>
<td>20</td>
</tr>
</tbody>
</table>
</body> </html>
实际开发中是将样式写入css文件中link引入的，
这里为了方便展示写在一个文件中
