asp.net 2.0中tablecontrol搭配masterpage的小bug

在asp.net 2.0中，如果在一个masterpage页面中，使用服务端的table控件的话，如下所示，会在设置视图时，没了其中的contentplaceholder，

    <asp:Table ID="tbl" runat="server">
            <asp:TableRow>
                <asp:TableCell>
                    This is my header!
                </asp:TableCell>
            </asp:TableRow>
            <asp:TableRow>
                <asp:TableCell>
                    <asp:contentplaceholder id="_content" runat="server">
                    </asp:contentplaceholder>           
                </asp:TableCell>
            </asp:TableRow>
            <asp:TableRow>
                <asp:TableCell>
                    This is my footer!
                </asp:TableCell>
            </asp:TableRow>
        </asp:Table>  

   而如果用普通的页面table的话，则不会出现如下的问题，
  <table>
            <tr>
                <td>
                    This is my header!
                </td>
            </tr>
            <tr>
                <td>
                    <asp:contentplaceholder id="_content" runat="server">
                    </asp:contentplaceholder>           
                </td>
            </tr>
            <tr>
                <td>
                    This is my footer!
                </td>
            </tr>
        </table>
  微软已经确认是个小BUG拉，将会在下一个版本解决，具体参考：
