导出的GridView到Excel没有网格

我使用此代码出口的datagridview到excel导出的GridView到Excel没有网格

HtmlForm form = new HtmlForm(); 
Response.Clear(); 
Response.Buffer = true; 
string fileName = "TRAIL" + "[" + DatefromTxtBox.Text.Replace("/", "") + "_" + DatetoTxtBox.Text.Replace("/", "") + "]" + ".xls"; 
Response.AddHeader("content-disposition", "attachment;filename=" + fileName); 
Response.Charset = ""; 
Response.ContentType = "application/vnd.ms-excel"; 
StringWriter sw = new StringWriter(); 
HtmlTextWriter hw = new HtmlTextWriter(sw); 
AuditTrailGV.AllowPaging = false; 
AuditTrailGV.DataSource = (DataSet)ViewState["audit"]; 
AuditTrailGV.DataBind(); 
form.Controls.Add(AuditTrailGV); 
this.Controls.Add(form); 
form.RenderControl(hw); 
Response.Output.Write(sw.ToString()); 
Response.Flush(); 
Response.End();

的问题是这样的代码还捕捉格式/我的GridView的边界

这里的屏幕截图，

这是我在asp.net enter image description here

GridView和这是出现在我的EXCELL enter image description here

正如你所看到的那样，它改变了所有的行像gridview，我不希望它发生，尽可能多，如果我只能保留数据行的网格线，如果它不可能，删除所有网格线。

有帮助吗？我真的不喜欢我excell中的网格线

您可以尝试下面的代码并自定义下载数据的颜色。它也不会着色列和数据以外的行。

protected void DownloadExcel_Click(object sender, EventArgs e) 
{ 
    Response.ClearContent(); 
    Response.Buffer = true; 
    Response.AddHeader("content-disposition", string.Format("attachment; filename={0}", "Report.xls")); 
    Response.ContentType = "application/ms-excel"; 
    StringWriter sw = new StringWriter(); 
    HtmlTextWriter htw = new HtmlTextWriter(sw); 
    GridView1.AllowPaging = false; 
    GridView1.DataBind(); 
    GridView1.HeaderRow.Style.Add("background-color", "#FFFFFF"); 

    for (int i = 0; i < GridView1.HeaderRow.Cells.Count; i++) 
    { 
     GridView1.HeaderRow.Cells[i].Style.Add("background-color", "#bfc2c7"); 
    } 

    int j = 1; 
    foreach (GridViewRow gvrow in GridView1.Rows) 
    {   
     //gvrow.BackColor = color.White; 
     if (j <= GridView1.Rows.Count) 
     { 
      if (j % 2 != 0) 
      { 
       for (int k = 0; k < gvrow.Cells.Count; k++) 
       { 
        gvrow.Cells[k].Style.Add("background-color", "#EFF3FB");  
       } 
      } 
     } 
     j++; 
    } 
    GridView1.RenderControl(htw); 
    Response.Write(sw.ToString()); 
    Response.End(); 
}
