Table height rendering questions

I using the template builder > Basic Newsletter, which has two columns...left and right or main.  I'm trying to get the two to line up so the top text entries line up horizontally.  If I change the code it will render correctly with some email applications like gmail, apple mail but renders totally different in different versions of outlook.  I haven't modified the two sections below...

Any clues for me for this small adjustment to work?

<tbody><tr><td class="w140" height="15" width="140"></td></tr> - Left Col
<tbody><tr><td class="w470" height="15" width="470"></td></tr> - Right Col or main body section.

Thanks in advance
