I think you either have to impose some total width or apply an arbitrary
multiplier to the proportional widths (but that would only work if you are
sure the proportional values are within some reasonable range―some
programs simply convert real values to proportions by dropping the units,
so that would break this approach).

I have this problem in generating InDesign tables from DITA tables where
you know the proportional widths of the columns but not necessarily the
target table width (because the geometry is known only to InDesign). For
that case I provide a runtime parameter to set the nominal table width so
you at least get something.
