            for (int i = 0; i < gv.Columns.Count; i++)

            {

                    {

                        if (gv.Columns[j].VisibleIndex == k)

                        {

                            ICell cell = row.CreateCell(k);

                            cell.SetCellValue(gv.Columns[j].Caption.ToString());

                            if (gv.Columns[j].UnboundType.ToString() == "Decimal")

                            { UnboundType[gv.Columns[j].FieldName] = "Decimal"; }//数字

                            else

                            { UnboundType[gv.Columns[j].FieldName] = ""; }//字符

                            k++;
