Thank you Wolfgang for examples. Now I got idea of background. Nice.
But actually I want something different. I couldn't describe this more
clearly than before so I attach PDF file that shows what I want to do.
(I made it with the help of asymptote: first I made a table in LaTeX,
then the table was put in background and after braces and letters were
placed on top of the table.)
I thought may be there is context (mkiv) way to do this, i.e. one
could specify which rows in a column to be grouped and what symbol will
be put after a brace.
If there is no simple (elegant, context-way?) solution then I have to
use "non-elegant" (imho, ugly) way: add an additional column with brace
and symbol.

WBR, Vladimir Lomov.
P.S. I'm impressed how you made a brace in metapost. I alway wonder how
people could write numbers that gives a nice figure (may be by triali
and error?).

The reason that every major university maintains a department of
mathematics is that it's cheaper than institutionalizing all those people.
