DataList is outside the table

I want to put a DataList in table but my DataList shows outside the table... I don't understand why.

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder2" Runat="Server">
    <table class="four_tile_table" border="1" cellpadding="0" cellspacing="0" width="100%">
        <tbody>
        <tr>
          开发者_C百科  <asp:DataList ID="DataList1" runat="server" DataSourceID="SqlDataSource1" 
                RepeatDirection="Horizontal" RepeatColumns="2" CellPadding="0">
            </asp:DataList>
        </tr>
        </tbody>
    </table>
</asp:Content>

I have the same behavior with the ContentPlaceHolder in my MasterPage, if I put it inside a table, it shows outside.

Thank you

I am not sure what do you mean by you are seeing it outside the table. But onething is you are missing

< td>

tags in your table layout.

Try wrapping the <asp:DataList> with a <td></td>
