1.

<asp:TemplateField HeaderText="总额">
          <ItemTemplate>
          <asp:Label ID="lblqty" runat="server"  Text='<%#Bind("QTY") %>'>'></asp:Label>//绑定数据源字段
          </ItemTemplate>
          </asp:TemplateField>

2.合并某一列相同的行

 ///  <summary>   
    ///   合并GridView列中相同的行   
    ///   </summary>   
    ///   <param   name="GridView1">GridView对象</param>   
    ///   <param   name="cellNum">需要合并的列</param>   
    public static void GroupRows(GridView GridView1, int cellNum)
    {
        int i = 0, rowSpanNum = 1;
        while (i < GridView1.Rows.Count - 1)
        {
            GridViewRow gvr = GridView1.Rows[i];
            for (++i; i < GridView1.Rows.Count; i++)
            {
                GridViewRow gvrNext = GridView1.Rows[i];
                if (gvr.Cells[cellNum].Text == gvrNext.Cells[cellNum].Text)
                {
                    gvrNext.Cells[cellNum].Visible = false;
                    rowSpanNum++;
                }
                else
                {
                    gvr.Cells[cellNum].RowSpan = rowSpanNum;
                    rowSpanNum = 1;
                    break;
                }
                if (i == GridView1.Rows.Count - 1)
                {
                    gvr.Cells[cellNum].RowSpan = rowSpanNum;
                }
            }
        }
    }

2.2根据某一列合并相同的行 同时合并其他指定列

 ///  <summary>   
    ///   合并GridView列中相同的行
    ///  根据GridView某特定相同的行 同时可以合并其他列 
    ///   </summary>   
    ///   <param   name="GridView1">GridView对象</param>   
    ///   <param   name="cellNum">需要合并的列</param>   
    public static void GroupRows(GridView GridView1, int cellNum)
    {
        int i = 0, rowSpanNum = 1;
        while (i < GridView1.Rows.Count - 1)
        {
            GridViewRow gvr = GridView1.Rows[i];//上一行
            for (++i; i < GridView1.Rows.Count; i++)
            {
                GridViewRow gvrNext = GridView1.Rows[i];//下一行
                if (gvr.Cells[cellNum].Text == gvrNext.Cells[cellNum].Text)//判断合并的条件
                {
                    gvrNext.Cells[cellNum].Visible = false;
                    gvrNext.Cells[cellNum + 1].Visible = false;
                    gvrNext.Cells[cellNum + 4].Visible = false;
                    rowSpanNum++;
                }
                else
                {
                    gvr.Cells[cellNum].RowSpan = rowSpanNum;
                    gvr.Cells[cellNum + 1].RowSpan = rowSpanNum;
                    gvr.Cells[cellNum + 4].RowSpan = rowSpanNum;
                    rowSpanNum = 1;
                    break;
                }
                if (i == GridView1.Rows.Count - 1)
                {
                    gvr.Cells[cellNum].RowSpan = rowSpanNum;
                    gvr.Cells[cellNum + 1].RowSpan = rowSpanNum;
                    gvr.Cells[cellNum + 4].RowSpan = rowSpanNum;
                }
            }
        }
    }
