呵呵，仅IE有效：）
前台代码：
<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>

   


   

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            GridView1.Style.Add("position", "absolute");
            GridView1.DataSource = GetDataSet();
            GridView1.DataMember = "testtable";
            GridView1.DataBind();
        }
    }

    private DataSet GetDataSet()
    {
        DataTable dt = new DataTable("testtable");
        dt.Columns.Add("Col1", typeof(int));
        dt.Columns.Add("Col2", typeof(string));
        dt.Columns.Add("Col3", typeof(string));
        dt.Columns.Add("Col4", typeof(string));

        DataRow dr;

        for (int i = 0; i < 10; i++)
        {
            dr = dt.NewRow();
            dr[0] = i;
            dr[1] = "Val" + i.ToString();
            dr[2] = "Val" + i.ToString();
            dr[3] = "Val" + i.ToString();
            dt.Rows.Add(dr);
        }

        DataSet ds = new DataSet();
        ds.Tables.Add(dt);
        return ds;
    }
}
