Row-wise percentages

[gah-bo]

Is there any way to add row-wise percentages in this library?

Essentially, I have the same need as this user expressed on issues for a similar R library to this one, table1 (specific issue is benjaminrich/table1#38)

I have figured it out with that other library but am looking for non-hacky alternatives - I wonder if this is a feature this library supports, is planned to be added eventually, or if its just been ruled out.
