github markdown colspan

Question

Is there a way to have 'colspan' on github markdown?

I'm trying to create a table where one row takes up four columns.

| One     | Two        | Three   | Four          | 
| ------------- |-------------| ---------| ------------- |
| One                | Two               | Three          | Four                |

| One     | Two        | Three   | Four          | 
| ------------- |-------------| ---------| ------------- |
| Span Across ||||

You can use HTML tables on GitHub (but not on StackOverflow)

<table>
  <tr>
    <td>One</td>
    <td>Two</td>
  </tr>
  <tr>
    <td colspan="2">Three</td>
  </tr>
</table>
