Re: How to Assign Class to HTML Table using a Filter

[John MacFarlane <jgm-TVLZxgkOlNX2fBVCVOL8/A@public.gmane.org>]

I don't know anything about PHP, but if you look at
the API docs for Text.Pandoc.Definition, you'll see
that the Table element doesn't have attributes
(including class).

Best you can do is insert it into a Div with
attributes.
