except <example> means *fatness* won't be rendered emphasized (this is an
excerpt from a long list, with "dividers" like
---    *fatness*    ----
---    *individual BP*    ----

again, this presents problems for the "dividers", which I would like to span
both columns (I don't think there's a way to represent such in emacs-wiki?). 
Also, although I insert the dividers manually, the list is just pasted from
another program and comes lined up nicely for <pre> format.  Quite often I just
paste such output into a file and surround with <pre> or <example> rather than
troubling to convert to table format.

While on the subject of tables (sort of), I often want to put maths like P(A|B)
into a file.  I can prevent it being rendered as a table by writing =P(A|B)=,
but then it comes out in fixed font.  Is there an alternative method to say
"emacs-wiki please don't attempt to render this part"?

Yes, much better, thanks.
