Comment (by darij):
OOPS, I was stupid: With your convention, `P.poset()` would not be
`P.superstandard_tableau().poset()` but rather something like
`P.tautological_tableau().poset()`, where `tautological_tableau()` puts
the pair of the coordinates of each cell into that cell (another function
that probably needs to be made). For this method to generalize to
arbitrary tableaux, though, one would have to check that all entries are
pairwise distinct, which is a waste of time (OK, so a `check` variable?).
But to be honest, I'd very much prefer to have this method defined on
partitions first and later maybe add it to tableaux as well. If I were to
search for it, I would definitely not have started by constructing a
tableau out of `p`...
