关于ListView控件问题

<asp:ListView ID="ListView1" runat="server" DataKeyNames="product_id" 
               DataSourceID="SqlDataSource1" GroupItemCount="3" 
               onselectedindexchanged="ListView1_SelectedIndexChanged" >
               <LayoutTemplate>
                   <table id="Table1" runat="server" width="370" >
                       <tr id="Tr1" runat="server" align="center">
                           <td id="Td1" runat="server">
                               <table ID="groupPlaceholderContainer" runat="server" border="0" style="">
                                   <tr ID="groupPlaceholder" runat="server">
                                   </tr>
                               </table>
                           </td>
                       </tr>
                       <tr id="Tr2" runat="server">
                           <td id="Td2" runat="server" style="" align="right">
                               <asp:DataPager ID="DataPager1" runat="server" PageSize="3">
                               <Fields>
                                     <asp:NextPreviousPagerField ShowNextPageButton="false" ShowPreviousPageButton="false" />
                                     <asp:NumericPagerField ButtonCount="10" />
                                     <asp:NextPreviousPagerField ShowNextPageButton="false" ShowPreviousPageButton="false" />
                                   </Fields>
                               </asp:DataPager>
                           </td>
                       </tr>
                   </table>
               </LayoutTemplate>
                   <GroupTemplate>
                       <tr ID="itemPlaceholderContainer" runat="server">
                           <td ID="itemPlaceholder" runat="server">
                           </td>
                       </tr>
                   </GroupTemplate>
                   <ItemTemplate>
                       <td id="Td3" runat="server" style="" >
                           <a href="product.aspx?id=<%#Eval("product_id")%>">
                             <img src="../ackj<%#Eval("product_img")%>" alt="" width="80" height="80" border="0" />
                           </a>
                       </td>
                   </ItemTemplate>
           </asp:ListView>我想在宽度为370的空间内显示3张图片,图片每张宽同高为80,但我显示出来的效果是三张图片紧接在一起,怎样才能把三张图片等距离的显示在宽度为370的空间内,头张和尾张在空间的最前和最后.谢谢各位啊
