Here's a elisp version:

* zip lists
#+name: a
| a |
|---|
| 1 |
| 2 |


#+name: b
| b |
|---|
| 4 |
| 5 |
| 6 |
| 7 |
| 8 |

#+name: c
|  c |
|----|
|  9 |
| 10 |
| 11 |

#+BEGIN_SRC emacs-lisp :var a=a[,0] b=b[,0] c=c[,0] :colnames '(a b c)
  (let*  ((l (list a b c))
          (max (apply #'max (mapcar #'length l))))
    (apply
     #'mapcar* #'list
     (mapcar (lambda (x) (append x (make-list (- max (length x)) ""))) l)))
#+END_SRC
