This is the code that worked for me
<div style="padding: 1px; height: 500px;width: 775px; overflow: auto;">
<table class="aligncenter" width = "755" style="border-width: 1px; border-color: #6b1ae4; background-color: #cfdfee;" border="1" cellspacing="1" cellpadding="1" align="center">
I think making the width of the table smaller than the width of the div did it - Then I just played with the numbers to get it just right
