in latex, it is conceptually natural to embed environments inside
others, but it always gives me a lot of troubles in doing so. for
example, "eqnarray*" can not be embeded in a tabular. my questions
are
1. is there any rule-of-thumb which determines which environment
can be nested in another one and which can't?
2. is there any trick to by-pass these constraints? for example, i
might really wish to nest some equations inside a tabular.
thanks!

Don't use LaTeX eqnarray. It's does not do a good job calculating spaces
and is not flexible. Learn to use the various alignment environments
provided by amsmath.sty instead.
The following should do what you want, except that the equation numbers
are automatically numbered in the order that the table is constructed.
If you want the equation number to go down the column automatically, it
will take more work.
The command \mitcmd and the environment "mitenv" are basically the same.
You can use wh

To answer your questions: There is no general rule of thumb about
the compatibility of environments when it comes to nesting them.
It all depends on the internal LaTeX code. If the environments
don't use tricks that involve the manipulation of character codes,
the horizontal/vertical/math modes, inserts (marginpar, footnote),
alignments, etc., then there is a better chance of compatibility.
In the case of putting aligned equations inside tabular, the &
character causes headache because LaTeX c

thanks for the long reply, :).
personally, i think it would be great that all environments (or some
basic ones) can be nested without constraints. it is convenient and
conceptually good. maybe it hurts the performance and it's also hard
to implement.
