I am exploring on trying to create a custom webpart and I am encountering this error:

In my source, I have a table in which a cell will contain SharePoint:DateTimeControl.

However it will

<asp:Table ID="interviewerAndApplicants" Visible="False" runat="server" Width="50%">
            Interview Timeslot:  <SharePoint:DateTimeControl ID="interviewSlot" runat="server" />

The weird thing is, if the SharePoint:DateTimeControl is NOT within a table cell, it displays perfectly in the design. However when it is placed within a cell, it will cause the error:

"Error Rendering Control: Object reference not set to an instance of an object"

in the designer view.

What exactly am I doing wrong/ missed out on doing? Thanks.
