Multi-column grid?

[webcraft]

Hi Jeffrey, after researching and experimenting with several page builder libraries, I came across Paver. I must say, it's exceptionally well-crafted and aligns closely with what I’m looking for. Thank you for creating such a fantastic tool!

I do have a specific requirement: the ability to define a multi-column grid. My current approach is to create a Block with multiple child slots. Here’s a simplified example using a table for demonstration:

<table>
      <tr>
            <td><!-- Paver::children() --></td>
            <td><!-- Paver::children() --></td>
      </tr>
</table>

However, this doesn’t seem to work as I expected. When I insert nested blocks into the child slots, only the first slot is preserved after saving, and the second slot ends up duplicating the children from the first.

Is it correct that each block is currently limited to a single child slot? If so, is there an alternative way to achieve this in Paver’s current state? How would you recommend implementing a multi-column layout?

Thanks in advance for your guidance!
