The Remarkup documentation states that Remarkup rules can be used inside table cells and while this seems true for simple things like bold, italic, etc., you can't nest tables. This is kind of a big deal for our documentation which makes heavy use of nested tables.

See below for an example of the syntax that I'd expect to work.

<table>
  <tr>
    <td>simple cell</td>
    <td>
    | Pipe | Table | Syntax |
    </td>
    <td>
      <table><tr><td>HTML Table Syntax</td></tr></table>
    </td>
  </tr>
</table>
