Hi - i'm trying to put two CTAs side by side with a border on them - but everytime I do, it adds a border to the space in between as well.

Thoughts? code snippet below
<table cellspacing="0" cellpadding="0" style="margin: 0px auto; border-color: #ffffff;" border="1px">
<tbody>
<tr>
<td width="250" height="35" style="background: #ffffff; font-weight: normal; font-size: 15px; color: #000000; padding: 5px 10px; text-transform: none; border-color: #000000; width: 250px; height: 35px;" border-width="1px" align="center"><a href="[@trackurl LinkID='cdd3557485a84c9ca755b0c78461dbaf' LinkName='DIAMONDS' LinkTag='TAG_8' LinkDesc='DESC_8' Tracked='ON' Encode='OFF' AppendSuffix='ON' Render='ON' LinkType='REDIRECT']https://www.helzberg.com/category/wedding/bands/shop+all+wedding+bands.do?c=23.103.5653&amp;pp=30&amp;sortby=ourPicksAscend&amp;sortType=1[/@trackurl]" alias="CTA" title="SHOP DIAMONDS" target="_blank" style="color: #000000; text-decoration: none; padding: 10px;" rel="noopener noreferrer">SHOP DIAMONDS</a></td>
