使用NPOI 转换Excel TO HTML （导出格式不如原生Excel好看）

            //HSSFWorkbook workbook = ExcelToHtmlUtils.LoadXls(strPath);
 
            //ExcelToHtmlConverter excelToHtmlConverter = new ExcelToHtmlConverter();
 
            //// Set output parameters
            //excelToHtmlConverter.OutputColumnHeaders = true;
            //excelToHtmlConverter.OutputHiddenColumns = false;
            //excelToHtmlConverter.OutputHiddenRows = false;
            //excelToHtmlConverter.OutputLeadingSpacesAsNonBreaking = true;
            //excelToHtmlConverter.OutputRowNumbers = true;
            //excelToHtmlConverter.UseDivsToSpan = true;
 
            //// Process the Excel file
            //excelToHtmlConverter.ProcessWorkbook(workbook);
 
            //var htmlFile = HttpContext.Current.Server.MapPath("/") + "doc\\" + fileName + ".html";
            //// Output the HTML file
            //excelToHtmlConverter.Document.Save(htmlFile);
 
            //docHtmlUrl = "http://" + HttpContext.Current.Request.Url.Host + ":" +
            //    HttpContext.Current.Request.Url.Port + "/doc/" + fileName + ".html";
