The following plain TeX input shows that good table output is possible
for short tables, without anything like a prototype row.  We just need
to use this underlying TeX functionality in texinfo.tex.  There's quite
a lot to consider, including line wrapping, items in the TODO file:

  - multicolumn * width to take up `the rest'.
  - @multitable: handle @hsep and @vsep.
  - @multitable: repeat table headings if multiple pages long.
  - @multitable: support a heading line concept (<thead> in HTML).

this thread too suggesting mixing column fractions and prototypes:
