The "border" attribute has nothing to do with it. It's the "frame" attribute
which sets the default top and bottom borders.

No. The CSS should be in the header, not an attribute of the tag. Have you
tried setting the 'HTML_HEAD_EXTRA' option?  somehting like:

#+HTML_HEAD_EXTRA: <style type="text/css">
#+HTML_HEAD_EXTRA: table {border-left: 1px solid black; border-right: 1px solid black;}
#+HTML_HEAD_EXTRA: </style>
