You can't do that. It is invalid HTML.
 You can't put a <a> in between a <tbody> and a <tr>. Try this instead:
-->
<tr onclick="window.location='#';">

</tr>

add style for pointer view
-->

[data-href] { cursor: pointer; }

When you work up to it, you'd want to use JavaScript to assign the click handler outside of the HTML
