Retrieve ancestor element with a certain data attribute

How can I retrieve an ancestor element with a certain data attribute by clicking one of its children elements?

I need to get the data-cell attribute when clicking either a <span> or a <div>. I tried to use node.parentElement, but when I click a span it returns me the div, and it's clear.

Is there something like node.parentElement.dataset.dataCell to get what I need?

<table>
 <tr>
  <td class="out" data-cell="3-2-2015">
     <div>
        <span> Number one </span>
        <span> Number two </span>
        <span> Number three </span>
     </div>
  </td>
 </tr>
</table>
