> For example, I"d like to display a "!" heading within the table. Is this possible? This is simliar to what I"m trying to do:
Yes it is. You need to have "Use html" enbled at "Admin > Wiki" (it is not here at tw.o right now). Then use html tags for titles:
|image||_h1- newPage _/h1-|
inside the table cells, etc.
(where I wrote "_", I meant "less than" character, and by "-", I meant "more than" character)
(I cannot write html tags here because they are not shown and removed later on from the post if you re-edit it).
See a working example, for instance, here:
http://gclub.cursos.ourproject.org (titles in orange inside normal table)
