That works fine as long as the "alignment" glue is of
order fil, so regular "r" or "l" column types are fine.

You might be thinking of "dotseqn" with leaders going to the
equation number.

Nothing looks difficult here, and Phil's answer did provide for
the three-dot groupings.  Of course I would recommend defining
a macro with the leaders command.  And also centering the dots
in the box. And ending with \kern\z@ so that the leaders don't
disappear at "&".
