Text after a table in WordPress editor – Help!

Hi: I have a table with the following attributes in a wordpress page.

<table class=”alignleft” border=”0″ cellspacing=”2″ align=”left”>
<tbody>
[…]
</tbody>
</table>
<h1>Related research and readings</h1>

Externally, the title “related research and readings” displays under the table. Great! But here is the problem: in the WordPress visual editor, all the text after the table is displayed to the right side of it, making writing and formatting extremely convoluted. I try to hit RETURN but all it does is take it down one line, both externally and on the visual display.

Is there something I need to add to the table property so it does not stick all following text to its right? Or some break after it? The puzzling piece is that the text displays correctly externally, but is only broken in the visual editor.

Thanks in advance!
