Displaying the records horizontally in ASP.Net Repeater Control

Hi Everyone;

I want to limit the records to 18 in every line,  then the next records goes to the nextline?

Any idea how to do it?

<asp:Repeater id="Repeater2" runat="server" >
        <HeaderTemplate >
            <table border="1" width="100px">
        </HeaderTemplate>
        <ItemTemplate>
                <asp:Literal ID="litRowStart" runat="server"></asp:Literal>
                <td><%# DataBinder.Eval(Container, "DataItem.iData") %></td>
                <asp:Literal ID="litRowEnd" runat="server"></asp:Literal>
        </ItemTemplate>
        <FooterTemplate >
            </table>
        </FooterTemplate>
    </asp:Repeater>

Thanks;
