The right code is this one
#+NAME: TA
| col1 | col2 |
|------+------|
|    1 |    2 |
#+NAME: TB
| col3 |
|------|
|    3 |
#+BEGIN_SRC emacs-lisp :var t1=TA t2=TB :colnames no
(insert-at 1 (cl-mapcar #'append t1 t2) 'hline)
#+END_SRC
#+RESULTS:
| col1 | col2 | col3 |
|------+------+------|
|    1 |    2 |    3 |
#+begin_src elisp :noexport
(defun insert-at (n list element)
  "Insert ELEMENT into LIST at position N.
I.e., (eq ELEMENT (nth N (insert-at N LIST ELEMENT)))."
  (if (eq n 0)
      (cons element list)
    (let ((link (nthcdr (1- n) list)))
      (setcdr link (cons element (cdr link))))
    list))
#+end_src
