If you want to write new tabbing macros, probably the best
would be to read The TeXbook. Or else see plain.tex file on
your system, but you're on your own here -- there are no
comments to guide you.
If you want to use \+ and \settabs inside your macros, then
it's much easier.
\+ is defined as an outer macro, therefore it cannot be used
inside another macro. But \tabalign (which is what \+
calls) can. Unfortunately, \settabs will not work if you
use \tabalign in the sample line:
\settabs\tabalign Text& More text&\cr % <- doesn't work
because \settabs looks ahead for a \+ and doesn't find it.
Probably the easiest way to deal with this is to redefine \+
to be non-outer:
\settabs\+ \quad& \quad&\cr
\+ 1& 2& 3\cr
\+ & 4& 5\cr
\+ & & 6\cr
