/*
另外一种就是先定义好Excel模板,然后输出指定格式的内容,这些内容通过开始单元格名称定位,然后写入内容,但是这种功能比较强大,输出的Excel内容也比较整齐。
1. 首先在Web.Config中配置下
<system.web>
<identity impersonate="true"></identity>
</system.web>
2. 创建一个Excel模板文件,如下图所示,当然这个是简单的Excel模板,你可以定义很复杂
http://images.cnblogs.com/cnblogs_com/wuhuacong/Report_Excel.jpg
3. 在网站的根目录中创建一个Temp目录,给EveryOne读写权限,当然你也可以给AuthenticatedUsers
4. 辅助类代码
