Answer 1

public void mergetable(string console) 
    { 
        for (int i = ProductList.Items.Count - 1; i > 0; i--) 
        { 
            HtmlTableCell oCell_previous = ProductList.Items[i - 1].FindControl(console) as HtmlTableCell; 
            HtmlTableCell oCell = ProductList.Items[i].FindControl(console) 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) 
            { 
                oCell.Visible = false; 
                oCell_previous.RowSpan += oCell.RowSpan; 
            } 
        }     } 
调用方法 
protected void ProductList_PreRender(object sender, EventArgs e) 
    { 
        mergetable("leixing"); 
        mergetable("pinpai"); 
    } 前面aspx 
<asp:Repeater ID="ProductList" runat="server" OnPreRender="ProductList_PreRender" OnItemDataBound="ProductList_ItemDataBound"> 
                <ItemTemplate> 
                    <tr> 
                        <td align="center" valign="middle" bgcolor="#FFFFFF" id="leixing" runat="server"> <%#Eval("brandname") %> </td> 
                        <td align="center" valign="middle" bgcolor="#FFFFFF" id="pinpai" runat="server"> <%#Eval("producttypename") %> </td> 
                        <td align="left" valign="middle" bgcolor="#FFFFFF"> <a href=' <%#"jieshao.aspx?id="+Eval("id") %>' target="_blank"> <%#Eval("name") %> </a> </td> 
                      <td align="center" valign="middle" bgcolor="#FFFFFF"> 
        <div  style="margin-top:-20px;"> <table width="100" border="0" cellpadding="1" cellspacing="0"> 
                              <tr> 
                                <td width="95" align="center" valign="top"> <img src="../images/line.gif" width="45" height="1" alt="line" /> </td> 
                                <td width="25" rowspan="2" align="center" valign="top" id="pdf"> <asp:Literal ID="pdfurl" runat="server"> </asp:Literal> </td> 
                              </tr> 
                              <tr> 
                                <td align="center" valign="top" id="tuxiang"> <input type="hidden" id="hiddenid" value=' <%#Eval("id") %>'  runat="server" /> <input type="hidden" id="hiddenname" value=' <%#Eval("name") %>'  runat="server" /> 
                                  <asp:Literal ID="picurl" runat="server"> </asp:Literal>                                </td> 
                              </tr> 
                        </table> 
</div> 
                      </td> 
                  </tr> 
                </ItemTemplate> 
              </asp:Repeater>

public static void MergeRow(GridView gView, int Column, int Compare1) 
        { 
            int i = 0; 
            int j = 0; 
            int rowSpan; 
            string str = ""; 
            string strTarget = ""; 
            for (i = 0; i < gView.Rows.Count; i++) 
            { 
                rowSpan = 1; 
                strS= gView.Rows[i].Cells[Compare1].Text;                 for (j = i + 1; j < gView.Rows.Count; j++) 
                { 
                    strTarget = gView.Rows[j].Cells[Compare1].Text; 
                    if (str.Length > 0 && str != "&nbsp;" && string.Compare(str, strTarget) == 0) 
                    { 
                        rowSpan += 1; 
                        gView.Rows[i].Cells[Column].RowSpan = rowSpan; 
                        gView.Rows[j].Cells[Column].Visible = false; 
                    } 
                    else 
                    { 
                        break; 
                    } 
                } 
                i = j - 1; 
            }
