    oStyle.BorderBottom = NPOI.SS.UserModel.BorderStyle.THIN;
    oStyle.BorderLeft = NPOI.SS.UserModel.BorderStyle.THIN;
    oStyle.BorderRight = NPOI.SS.UserModel.BorderStyle.THIN;
    oStyle.BorderTop = NPOI.SS.UserModel.BorderStyle.THIN;
    oStyle.BottomBorderColor = NPOI.HSSF.Util.HSSFColor.BLACK.index;
    oStyle.LeftBorderColor = NPOI.HSSF.Util.HSSFColor.BLACK.index;
    oStyle.RightBorderColor = NPOI.HSSF.Util.HSSFColor.BLACK.index;

//TODO将数据放入newSheet 


//移除范本档
workbook.RemoveSheetAt(0);

/// 读取范例EXCEL
/// 
/// 
  
  
private static HSSFWorkbook ReadSampleExcel()
{
    FileStream fm;
    HSSFWorkbook workbook;

    //范本档路径
    string Path = HttpContext.Current.Server.MapPath(string.Format("~/bin/Common/Data/{0}.xls", "CDR210Sample"));
    try
    {
        //读取范本
        fm = new FileStream(Path, FileMode.Open, FileAccess.Read);

        //范本Stream转成EXCEL
        workbook = new HSSFWorkbook(fm);
    }
    catch (Exception)
    {
        workbook = null;
