Dear Tadziu,

thank you very much for the hint, it works like a charm.

In addition to your "space 0" hint, I inserted an (otherwise empty) row
on top of the material which holds the macro for the vertical curly
brace, and inserted a few spaces here and there (.sp .25) which also
helped positioning the vertical material even though I do not fully
understand the mechanism of interaction.

The result is absolutely what I intend to have, and good enough for the

Thank you again!

That appears to be a peculiarity of the interaction between
eqn and tbl, which looks like its aligning the top of the
equation with whatever alignment point was specified in tbl.
You can see this if you try top-aligned and bottom-aligned
placement in tbl instead of vertical centering.  For vertical
centering (and if your equation has approximately equal
height and depth), you can usually obtain the desired result
by saying "space 0" inside the equation, which overrides
the default extra pre- and post-line space requested by eqn.
