I copy/pasted your code into a new epub in sigil. When I ran epubcheck, it complained the </tr> was missing so I added it. At that point, epubcheck had no issues with the code (epubcheck 4.26 is the version in use) reporting no problems found.
Code:
<table class="cbj_header">
<tbody>
<tr data-calibre-jacket-searchable-tags="1" style="color:white; display:none"></tr>
</tbody>
</table>
