使用Aspose.Cells导出excel
先提供数据源，使用aspose创建excel的单元格和各种样式，插入图片，冻结单元格，行高等
public string ExportDemo()
{
ViewResultModel result = ViewResultModel.Create(true, "");
//获取数据源,为了能通用，转为DataTable，其他类型的数据源也是一样的
DataTable humanList = Power.Systems.StdSystem.HumanDO.FindAllByTable();
Dictionary
header.Add("编号", "Code");
header.Add("姓名", "Name");
header.Add("部门", "DeptName");
header.Add("头像", "HeadSmall");
OutPutFile(header, humanList, "公司人员报表");
return result.ToJson();
