I think the interesting and general task here is:
(i) Two columns, left one left-aligned, right one right-aligned.
(ii) In the spanning header cell, what is left-hand to the fill,
should be typeset with tight interword space and left-aligned
with the first column below, what is right-hand to the fill,
should be typeset with tight interword space and right-aligned
with the second column below.
The OP mentions LaTeX's tabular environment and \multicolumn,
so in the first instance we wonder whether this can be achieved
with Standard LaTeX, or (in the second instance) with some
special LaTeX package.
I really wonder how the fill could "press" its surroudings apart
appropriately. I also wonder how this could be achieved
with Plain TeX.
A solution for Standard LaTeX could be (I guess) using type `p'
for the \multicolumn. Yet this would require adjusting the width
of the spanning cell manually.
There may be a LaTeX package that automates this by
a macro-based and perhaps .aux-based procedure,
rather than using TeX's built-in \halign directly.
I think Donald Arseneau has made a similar package.
If it is so difficult with LaTeX, can Phil Taylor solve it without LaTeX?
