Not sure if this is okay, but I used p tag here to introduce a line break after
each group.

nit:  Can use lines less than 80-chars be doing:
<td>
  <p...></p>
</td>

We aren't strict about line length in HTML, but does make reviewing a little
nicer.

That's fine - how long is the list?  I was thinking that it would be long enough
that it's better to just separate them with spaces.

I have 9. With space, the list looks a little crammed, but I think space works
better in case the list grows long. Thanks!
