In Mathematica, TableForm is not itself a data structure, but only something that takes a data structure and prints it in different forms. Is this similar to your implementation? >> But I do think we want this type of functionality in sympy, especially >> something like TreeForm (I think that is what it is called) that >> displays a nice expression tree. > > Great, I agree. OK, Cool. I do think we want this in sympy as a table is an appropriate way of displaying symbolic expressions. If TableForm were focused more on displaying non-symbolic data, then I would say sympy is probably not the place for it. I can imagine numpy implmenting something like this, but surely it won't be tied into sympy and handle all of our different printing formats.
