设置导出列

讲解：在做导出数据的时候除了要经过条件筛选想要的数据，又有的时候只想导出某一列或者多列数据，就需要在原有的导出方法上改动一下。
控制器代码：

public ActionResult ExportFundRunningWaterr(int BankAccountID, string CompanyName, string Remark, string time1, string time2, string checkChinse){

中间省略查询分页数据

string[]checkChinseColumnName=checkChinse.Split(newchar[]{','},StringSplitOptions.RemoveEmptyEntries); //这是将在页面所要导出的某列数据拼接成字符串传回后台，然后通过”,”分割成string数组
//Excel表格的创建步骤
            //第一步：创建Excel对象
            NPOI.HSSF.UserModel.HSSFWorkbook book = new NPOI.HSSF.UserModel.HSSFWorkbook();
            //第二步：创建Excel对象的工作簿
            NPOI.SS.UserModel.ISheet sheet = book.CreateSheet();
            //第三步：Excel表头设置
            #region Excel表头设置
            //给sheet添加第一行的头部标题
            NPOI.SS.UserModel.IRow row1 = sheet.CreateRow(0);//创建行
//通过for循环将生成表头
            for (int i = 0; i < checkChinseColumnName.Length; i++)
            {
                row1.CreateCell(i).SetCellValue(checkChinseColumnName[i]);
            }

            #endregion
            //第四步：for循环给sheet的每行添加数据
            #region 给sheet的每行添加数据
            for (int i = 0; i < list.Count; i++)
            {
                NPOI.SS.UserModel.IRow row = sheet.CreateRow(i + 1);
for循环给sheet的每行添加数据，判断下添加数据的字段名
                for (int j = 0; j < checkChinseColumnName.Length; j++)
