Although I would second Bob's recommendation, the issue here is
twofold:

1. You'll need to set your header margin such that the table exactly
fills the space between the header margin and top margin.

2. Wherever you have a table, Word requires at least one paragraph of
plain text (even if empty) following the table. This is what is
causing your space. Display nonprinting characters so that you can
see the empty paragraph. It may suffice to format the font as 1
point, but often it causes fewer problems to format it as Hidden
(because you can then see and work with it when you display
nonprinting characters). Naturally, you'll need to hide nonprinting
characters before the empty paragraph will disappear.

Again, many thanks - tried Bob's solution and it works. Also tried yours,
and it works as well. Thankyou for your time.
