说明：开发环境 vs2012 asp.net mvc4 c#
注意：Excel模板有多个sheet页，导出Excel的时候，同时给多个sheet页填充数据
1、项目结构
3、Excel模板（注意sheet页的名称）
4、HTML代码（导出按钮）
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="EasyuiCombotree.aspx.cs" Inherits="MvcAppTest.EasyuiCombotree" %> <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml">

5、Home控制器代码
