由于直接生成的表格样式很丑，添加了给页面加css的步骤
页面输出方式新增一种，可避免输入filename参数和生成html文件
public void ExcelToHtml(string fileName, IWorkbook workbook) { ExcelToHtmlConverter excelToHtmlConverter = new ExcelToHtmlConverter(); // 设置输出参数 excelToHtmlConverter.OutputColumnHeaders = true; excelToHtmlConverter.OutputHiddenColumns = false; excelToHtmlConverter.OutputHiddenRows = false; excelToHtmlConverter.OutputLeadingSpacesAsNonBreaking = true; excelToHtmlConverter.OutputRowNumbers = true; excelToHtmlConverter.UseDivsToSpan = true; // 处理的Excel文件 excelToHtmlConverter.ProcessWorkbook(workbook); //添加表格样式 excelToHtmlConverter.Document.InnerXml = excelToHtmlConverter.Document.InnerXml.Insert( excelToHtmlConverter.Document.InnerXml.IndexOf("<head>", 0) + 6, @"<style>table, td, th{border:1px solid green;}th{background-color:green;color:white;}</style>" ); //方法一 return Content(excelToHtmlConverter.Document.InnerXml); //方法二 ////输出的html文件 需创建对应的文件目录 这里是根目录下的doc文件夹 //var htmlFile = System.Web.HttpContext.Current.Server.MapPath("/") + "doc\" + fileName + ".html"; //excelToHtmlConverter.Document.Save(htmlFile); //Response.Redirect("http://" + System.Web.HttpContext.Current.Request.Url.Host + ":" + // System.Web.HttpContext.Current.Request.Url.Port + "/doc/" + fileName + ".html"); }
