                        DataColumn dc2 = mytable.Columns.Add("dcDocPath", Type.GetType("System.String"));
                        DataRow ro = mytable.NewRow();
                        ro["dcDocContent"] = "找不到商城编号";
                        ro["dcDocPath"] = NAME;
                        mytable.Rows.Add(ro);
