            HtmlTableCell oCell = rptList.Items[i].FindControl("tdName") as HtmlTableCell;



            oCell.RowSpan = (oCell.RowSpan == -1) ? 1 : oCell.RowSpan;

            oCell_Previous.RowSpan = (oCell_Previous.RowSpan == -1) ? 1 : oCell_Previous.RowSpan;



            if (oCell.InnerText == oCell_Previous.InnerText)
