I think that if the column contains a single word then it will
expand a column if the word does not fit. For example:
Here is a snippet from groff_www.html, the first version is broken as
the width for the column which contains "MTO" is (I think) to narrow.
Thus my browser makes the "MTO" fit into this column by widening it.
This then causes subsequent paragraphs to be misaligned. The second
copy of this file, I've increased the percentage for the "MTO" column
by reducing the percentage of the width column. The result is much
improved.
Also grohtml does contain some rounding errors when computing these
(but in these examples I've fixed those by hand to illustrate the
problem).
