With "display: none" the table row does not affect the column widths at
all.

What would be ideal is if we could eliminate the need for any prototype
row at all as this does not work well across output formats, leading users
to be confused.  However, I am not sure how easily it could be done in TeX.
In texinfo.tex \halign is used (this is a TeX primitive) but it is only
used with one row.

I wonder if we could use it with multiple rows so that columns had
the width of the widest text, plus some padding.  This would not
allow for text wrapping but could be ok for short tables.
