GridView获取列/行的高度和宽度

<form id="form1" runat="server">
<div>
    <asp:Table ID="Table1" runat="server">
        <asp:TableRow>
            <asp:TableCell>
            </asp:TableCell><asp:TableCell>
                <asp:GridView ID="GridView2" runat="server" ShowHeader="false">
                </asp:GridView>
            </asp:TableCell></asp:TableRow>
        <asp:TableRow>
            <asp:TableCell>
                <asp:GridView ID="GridView3" runat="server" ShowHeader="false">
                </asp:GridView>
            </asp:TableCell><asp:TableCell>
                <asp:GridView ID="GridView4" runat="server" ShowHeader="false">
                </asp:GridView>
            </asp:TableCell></asp:TableRow>
    </asp:Table>
</div>
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
</form>

下面是代码behinde:

protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                DataTable dt1 = new DataTable();
                DataTable dt2 = new DataTable();
                DataTable dt3 = new DataTable();

                DataRow row;

                dt1.Columns.Add(new DataColumn("Description", Type.GetType("System.String")));
                dt1.Columns.Add(new DataColumn("ROXORZZOZO!!", Type.GetType("System.String")));
                dt1.Columns.Add(new DataColumn("MY", Type.GetType("System.String")));
                row = dt1.NewRow();
                row["Description"] = "WOOOO";
                row["ROXORZZOZO!!"] = "EOOOOOOOOOOOOOOOOOOOOO!";
                row["MY"] = "My time to shine!";

                GridView2.DataBind();
                GridView3.DataBind();
                GridView4.DataBind();
