Okay, so have your program produce the table as output ("\begin
{tabular}{c|c} \hline A & B ..."), and then do
%latex
\sage{my_program(args...)}
Is that what you want?

Try
a = r"\begin{tabular}..."
to store the latex code in a string.

sage: from sage.misc.latex import Latex
sage: L = Latex()
At this point, "calling" L will try to convert its argument to a
string suitable for printing in latex:
sage: L(3+5)
8
sage: L(range(3))
\left[0, 1, 2\right]
sage: L("hello")
\text{hello}
Also, "L.eval(string, globals=globals())" will run Latex on string,
creating a png file with the output; it will use the parameters used
in initializing L -- in my situation, I didn't use any, but I could
have done
sage: L = Latex(debug=True, pdflatex=True)
for example. Finally, note that "latex" is defined to be "Latex
()" (or "Latex(density=130)" in the notebook), so I could have just
used "latex(3+5)", "latex(range(3))", etc., in my examples.
