You have two options to prevent the automatic highlighting of a row on hover:

<ul class="Vlt-list Vlt-list--simple">
	<li>Prevent it in the entire table: <code>Vlt-table--nowrap</code> on the table wrapper</li>
	<li>Prevent it on specific cells: <code>Vlt-nowrap</code> on those cells</li>
</ul>

Play with the frame width to see the behaviour in action
