Hi, thank you for your answer.

Your solution is OK but only for the example I gave (2 or 3 results). In practice I have about 10 results and the number of them may be variable... 
Furthermore :vars does not work on my version (I must use :var x=A :var y=B)...

Ta.

you could define a 3rd block C that takes the results from block A and B
as variable via :vars x=A y=B (A and B must be named blocks for this,
use a #+NAME: A line) and then do (list A x B y) in block C and use the
:results format that outputs a list as a table (often it is the default,
otherwise try :results table or so).
