二、设置数据格式：
在head中加入css定义

<style type="text/css">
.spercent
{
background-color:#ffff99;
mso-number-format:0.00%;
}
</style>
在css中加入：mso-number-format定义数据格式，格式可以在excel中查看自定义格式，具体可以参考一下：
mso-number-format:"0" NO Decimals
mso-number-format:"0\.000" 3 Decimals
mso-number-format:"\#\,\#\#0\.000" Comma with 3 dec
mso-number-format:"mm\/dd\/yy" Date7
mso-number-format:"mmmm\ d\,\ yyyy" Date9
mso-number-format:"m\/d\/yy\ h\:mm\ AM\/PM" D -T AMPM
mso-number-format:"Short Date" 01/03/1998
mso-number-format:"Medium Date" 01-mar-98
mso-number-format:"d\-mmm\-yyyy" 01-mar-1998
mso-number-format:"Short Time" 5:16
mso-number-format:"Medium Time" 5:16 am
mso-number-format:"Long Time" 5:16:21:00
mso-number-format:"Percent" Percent - two decimals
mso-number-format:"0%" Percent - no decimals
mso-number-format:"0\.E+00" Scientific Notation
mso-number-format:"\@" Text
mso-number-format:"\#\ ???\/???" Fractions - up to 3 digits (312/943)

导出的excel可以直接通过excel打开，效果如下:
