How to get span to take up the full height of the containing td

Question

I have a table, and in the left column I want to add an indicator for the row. I\'m using a span to render the indicator, but I can\'t get the span to take up the full height:

Answer 1

Should add overflow:auto to the span (and display:block of course)

<table>
   <tr>
      <td style="padding:0px;"><span style="height:100%; width:5px; background-color:pink;display:block;overflow:auto">&nbsp;</span></td>
      <td>Some content</td>
      <td>Some more content</td>
  </tr>
</table>
