Re: Cleaner Table Formatting when converting from Markdown to Latex?

[John MacFarlane <fiddlosopher-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

PS. If you don't worry about the too-wide issue, then you can "fix" it with this lua filter:

function Table(el)
  for _,spec in ipairs(el.colspecs) do
    spec[2] = nil -- set width to nil for a "simple" table
  end
  return el
end
