Repeater 导出数据到Execl后 木有格子线 怎么弄？
求 大神 帮忙 想个点子

------解决方案--------------------
#region 导出
protected void Export_Click(object sender, EventArgs e)
{ 

if (Session["dtexcel"] != null && Session["dtexcel"].ToString() != "")
{
DataTable dt = new DataTable();
dt.Columns.Add("产品名", typeof(string));
dt.Columns.Add("经销商", typeof(string));
DataTable dtexcel = (DataTable)Session["dtexcel"];
for (int i = 0; i < dtexcel.Rows.Count; i++)
{
DataRow row = dt.NewRow();
row["产品名"] = GetPName(dtexcel.Rows[i]["ProductID"].ToString());
row["经销商"] = GetPName(dtexcel.Rows[i]["DealerID"].ToString());
dt.Rows.Add(row);
}
CreateExcel(dt, "Record.xls");
}

}
#endregion

public void CreateExcel(DataTable dt, string FileName)
{
HttpResponse resp;
resp = Page.Response;
resp.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
resp.AppendHeader("Content-Disposition", "attachment;filename=" + FileName);
string colHeaders = "", ls_item = "";

//定义表对象与行对象，同时用DataSet对其值进行初始化 
//DataTable dt = ds.Tables[0];
DataRow[] myRow = dt.Select();//可以类似dt.Select("id>10")之形式达到数据筛选目的
int i = 0;
int cl = dt.Columns.Count;

//取得数据表各列标题，各标题之间以t分割，最后一个列标题后加回车符 
for (i = 0; i < cl; i++)
{
if (i == (cl - 1))//最后一列，加n
{
colHeaders += dt.Columns[i].Caption.ToString() + "\n";
}
else
{
colHeaders += dt.Columns[i].Caption.ToString() + "\t";
}

}
resp.Write(colHeaders);
//向HTTP输出流中写入取得的数据信息 

//逐行处理数据
foreach (DataRow row in myRow)
{
//当前行数据写入HTTP输出流，并且置空ls_item以便下行数据
for (i = 0; i < cl; i++)
{
if (i == (cl - 1))//最后一列，加n
{
ls_item += row[i].ToString() + "\n";
}
else
{
ls_item += row[i].ToString() + "\t";
}

}
resp.Write(ls_item);
ls_item = "";

}
resp.End();
}

你的Repeater1里面必须有table border=1
