I'm not aware of anything specific for this purpose. A starting point could be 
the `append' lisp function:

#+begin_src elisp :var table1=RK :var table2=SVD :colnames t
(append table1 table2)
#+end_src

#+RESULTS:
| met | Q1: | Q2 |  Q3 | total |
|-----+-----+----+-----+-------|
| RK  |   1 |  1 | 0.5 |   2.5 |
| SVD | 0.5 |  1 |   1 |   2.5 |
