I don't get your question. Wich values do you want to populate this square matrix? Or do you want a lot of matrices with all the size combinations?

What do you mean by a "table" in this context? Something displayed to the command window? A uitable() ? An array with 3 columns, the first for i, the second for j, and the third for A(i,j) ?
When you speak of A(i,j) do you mean A(1:12,1:12), or do you mean A(i(1),j(1)) A(i(2),j(2)), A(i(3),i(3)) and so on? If you do then
A(subs2ind(size(A), i, j))

syms A
>> for i = 1 : 12
for j = 1 : 12
disp(A(i,j)); %the sample action taken on A(i,j)
end
end
A
??? Error using ==> mupadmex
Error in MuPAD command: Index exceeds matrix dimensions.
Error in ==> sym.sym>sym.subsref at 1366
B = mupadmex('mllib::subsref',A.s,inds{:});
