关于datalist的用法

<asp:DataList ID="dlqiuzhi" runat="server" RepeatColumns="2"  Width="354px" RepeatDirection="Horizontal">
                                                    <ItemTemplate>
                                                        <div style="text-align: center">
                                                        
                                                        
                                                        <table width="33" height="76" cellpadding="0" cellspacing="0">
                          <tr>
                            <td><table width="124" height="94" border="0" align="center" cellpadding="0" cellspacing="0" bgcolor="#999999">
                                <tr>
                                  <td width="367" align="center" valign="middle" bgcolor="#FFFFFF"><a title='<%#Eval("videoTitle") %>' target=_blank href='play.aspx?id=<%#Eval("id") %>' >
                                                                <asp:Image ID="Image1" runat="server" Height="90px"  ImageUrl='<%#Eval("videoPicture") %>' Width="120px"  /></a></td>
                                </tr>
                            </table></td>
                          </tr>
                          <tr>
                            <td align="center" class="shenhong"> <a title='<%#Eval("videoTitle") %>' target="_blank" href='play.aspx?id=<%#Eval("id") %>' >
                                                               <%#operateMethod.interceptStr((string)Eval("videoTitle"),6) %>
                                                            </a></td>
                          </tr>
                      </table>
                                                        
                                                        
                                                            
                                                           
                                                           
                                                        </div>
                                                    </ItemTemplate>
                                                </asp:DataList>
这段程序显示的是两列多行。我想实现两列一行的效果，应该怎么改？
