This sounds like a good idea.
I create a table where two rows are grouped together.
(First row describes start condition, second row end condition.)
They alternate background color (2 rows white, 2 rows gray)
Sometimes the table is split inside a pair of rows which looks unprofessional:-)

In my case it would be
 ('KEEPTOGETHER', (0, 1), (2, 3), ...)
