listview table

I cant place a border around a row in a listview .

i tried adding a table.
I have tried a few variations but i can do border around a <td> but not <tr>
   <table  class="tbmyprod1">
  
        <asp:ListView ID="lvCatalog" runat="server">
            <LayoutTemplate>
                <asp:PlaceHolder ID="itemPlaceholder" runat="server"></asp:PlaceHolder>
            </LayoutTemplate>

        &nb ...
