I think this may be the pain of monospace, as it's browser/OS dependent,
though (comments below)...

So, it seems like it's the same font, but it's a trompe-l'oeil: it is
the default font of the site (Open Sans). However, it appears the
old-style docs use a different browser/OS dependent font in "verdana".
When I force it to verdana, we get the attached (enum_first has verdana,
enum_list has Open Sans). This seems to get the desired effect on the
function definition line, but it sets the descriptions to be verdana,
which seems to clash with the rest of the site.

(With my other comment of "can we get said signature into its own
row/block, I can make said issue go away easily :) Per your upthread
comment, I believe that would entail taking a go at DocBook and ensuring
it still looks good in the PDF build, which I am not ruling out trying...)

Another option is to make the font large in the tables, which helps with
the spacing. I'm not as much of a fan of that solution.

I did try using the "letter-spacing" CSS property, but the results
become fairly comical, fairly quickly.

I think Door #1 would be the optimal quick/best approach for a short
term resolution, pending other structural changes.
