Is the tab a tab provided by a plugin or is it a tab created within CB > Tab Management that you've added fields to? For a tab you've created and added fields to the best way to do this probably CSS. Alternative is to use a Delimiter field and substitutions to render your fields using custom HTML. Example as follows.
Code:
<table>
<tr>
<td>[cb_field1]</td>
<td>[cb_field2]</td>
</tr>
</table>
Please see the below tutorial for further substitution usage information.
