解决方案
解决方案二：
自己写个方法，自定义一个表格样式然后导出
解决方案三：
GridView导出Excel并进行格式化示例//对单元格字符串进行格式化处理protectedvoidGridView1_RowDataBound(objectsender,GridViewRowEventArgse){if(e.Row.RowType==DataControlRowType.DataRow){e.Row.Cells[3].Attributes.Add("style","vnd.ms-excel.numberformat:￥#,
解决方案四：
.00");}}//codego.net/tags/1/1///按指定格式定义输出的类型和文件名privatevoidExport(stringFileType,stringFileName){Response.Charset="GB2312";Response.ContentEncoding=System.Text.Encoding.UTF7;Response.AppendHeader("Content-Disposition","attachment;filename="+HttpUtility.UrlEncode(FileName,Encoding.UTF8).ToString());Response.ContentType=FileType;this.EnableViewState=false;StringWritertw=newStringWriter();HtmlTextWriterhw=newHtmlTextWriter(tw);GridView1.RenderControl(hw);Response.Write(tw.ToString());Response.End();}//加载输出信息SqlConnectionsqlcon=newSqlConnection(ConfigurationManager.AppSettings["conStr"]);protectedvoidPage_Load(objectsender,EventArgse){if(!IsPostBack){bind();}}//显示事件处理privatevoidbind(){SqlDataAdaptermyda=newSqlDataAdapter("selecttop10GoodsIDas商品ID,GoodsNameas商品名称,GoodsIntroduceas商品介绍,GoodsPriceas商品价格fromtb_GoodsInfo",sqlcon);DataSetmyds=newDataSet();sqlcon.Open();myda.Fill(myds);sqlcon.Close();GridView1.DataSource=myds;GridView1.DataBind();}
解决方案五：
使用NPOI吧
解决方案六：
html里根本没有列的概念excel不过仅仅是能够打开而已你想设置列宽自适应,应该导出excel,而不是html修改扩展名
