        {
            DataRow Drre = DataSet1.DataTable1.NewRow();
            Drre["col1"] = "cc";
            Drre["col2"] = "bb";
            Drre["col3"] = "dd";
            DataSet1.DataTable1.Rows.Add(Drre);

            DataRow Drre2 = DataSet1.DataTable1.NewRow();
            Drre2["col1"] = "cc2";
            Drre2["col2"] = "bb2";
            Drre2["col3"] = "dd2";

            DataRow Drre3 = DataSet1.DataTable1.NewRow();
            Drre3["col1"] = "cc3";
            Drre3["col2"] = "bb3";
            Drre3["col3"] = "dd3";
            DataSet1.DataTable1.Rows.Add(Drre3);

            DataRow Drre4 = DataSet1.DataTable1.NewRow();
            Drre4["name"] = "ธีรพัฒน์ กาทอง";
            DataSet1.DataTable1.Rows.Add(Drre4);
