表格隔行换色，节省代码的好方法

<style>

.db { border-collapse:collapse;}

.db tr{ background-color:expression('#F8F8F8,#EFEFEF'.split(',')[rowIndex%2]); }

</style>

<table width="100%" border="1" class="db">

<tr>

<td> </td>

</tr>

<tr>

<td> </td>

</tr>

<tr>

<td> </td>

</tr>

<tr>

<td> </td>

</tr>

</table>

上面是每一行隔行换色每两行一循环，下面是每一行隔行换色，每八行一循环

<style>

.db tr{

background-color:expression('#000000,#333333,#555555,#777777,#999999,#bbbbbb,#dddddd,#ffffff'.split(',')[rowIndex%8]);

}

</style>
