<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<head>

</head>

<body>

<?php echo $gridhtml;?>

</div>

</body>

</html>

设置数据网格风格的css样式文件内容：

.gridstyle{

width:700px;

margin:0px auto;

border-collapse:collapse;

text-align:center;

}

.gridstyle th ,td{

border:1px solid #aaa;

}

.gridstyle thead th{

border-bottom:2px solid #2d580b;

background-color:#8fc629;

color:#fff;

padding:10px 0px;

}

.gridstyle th{

background-color:#f2f4b9;

}

.gridstyle th.title{

background-color:#e3e685;

}

.gridstyle tfoot td{

border-width:0px;

text-align:right;

font-size:12px;

color:#777;

}

.gridstyle caption{

font-weight:bold;

padding:6px 0px;

color:#3d580b;

font-size:25px;

}

文件class.PageBar.php文件就是本blog中的那个分页类，将其拷贝到这个文件中即可。

最终效果：

MSIE 6.0

Firefox 1.0

Firefox 1.5

Opera 8.5

HTML 4.01

dfsa

dddd

aaaa

dfsd

dfdsfds

哈哈哈
