Getting Rid of Table Borders in HTML Emails

Question

I'm working on an HTML email campaign (no CSS allowed) so I'm forced to use tables, something I'm not super familiar with. I've got everything looking right EXCEPT the table borders. Whenever I create a new <tr> I cannot for the life of me get rid of the inner border around the content. I have tried a few tricks (border="0px", bordercolor="white", bordercolor="#ffffff", etc), but whenever I send a test message, the borders still show up black around my text and images.

This is really messing with my design flow. Is there any trick I don't know to getting rid of HTML table borders? Help!

Answer 1

 <table border="0" cellpadding="0" cellspacing="0" width="100%" style = "border-collapse: collapse;">
