Well, I wouldn't say it was discarded --- but there sure wasn't
a groundswell of support.
Looking at it again, I'd be inclined not to bother with the
morerows trick but just to have an operator name entry in each row.
This table is a bit of an outlier anyway, I'm finding --- very few
of the operator tables have multiple entries per operator name.
