A problem has been found with centering a heading over a pair of
columns, where the items in the columns themselves are centered or
numeric and the title is wider than the other data in the columns.
(I.e. the widths of the columns need to be enlarged to make the
title fit.)  The extra width needed to make the title fit all gets
added to the second column, instead of being evenly distributed
among the columns.  This messes things up.

The simplest fix seems to be to put an explicit width on the first of
the two problem columns.  If you get the width about right, then the
second column will get padded out to a similar width when the extra
needed for the title gets added to it.

It is possible that this problem crops up in broader circumstances
than the ones I have described above;  I have not investigated it
exhaustively.
