When you want to change spanning in the current implementation of @Tab,
you have to define not only the spanning row as a format, you have also
to consider the format immediatly preceding that row, because it has to
use the @Over construct, which effectively ties the two together.
Given 
        1:   A   B    C
        2:   A   spanning
the formats for row 1 differs when followed by a row 2 compared with
when a row 1 is followed by a row 1. Imagine the work to be done if you
want to use a row 2 in a range of different formats...
That's what I ment with 'transitions'.

If Jeff manages to eliminate this dependency, it will make @Tab much
more usefull.
