自已做的,本来想在网上找前辈们做的,可是总找不到这种例子,要么找出来的太复杂,
要么就没法用,索性自己写了一个.看看还可以用!贡献出来,估计和我一样的菜鸟用的着!
代码如下:
<html>
<style>
body{
font-size:9pt;
}
table,th,td{
font-size:9pt;
}
.lsitTalbe{
table-layout:fixed;
width:30%;
border-collapse:collapse;
border-color:#507010;
color:#003300;
}
.pageda{
font-family:Webdings;
font-size:12pt;
color:#CCCCCC;
cursor:default;
}
.pageua{
font-family:Webdings;
font-size:12pt;
}
.even{
background:#e8f8d0;
}
.odd{
background:#f8fcf0;
}
.header{
background:a0dc40;
color:003300;
}
</style>
