This also doesn't seem to work with shr.

Yes, the most obvious use-case here would be a Pandas dataframe (or the
equivalent from any other statistical package).  In the Pandas case, the
HTML looks pretty much like what you posted.

But the capability to right-align is a somewhat separate question from
the notation used to chose it.  If shr could render table with right
alignment, one could at least do some ad-hoc stuff for the main cases.
