Thanks I knew about it, but it seems very sophisticated and column, not
row based.

Meanwhile I found the following, R-based, solution 

* Using R to combine columns, important the first row must coincide!
 #+tblname: TC
 | a | b | c |
 |---+---+---|
 | 1 | 2 | 3 |
 | 7 | 8 | 9 |
 
 #+tblname: TD
 |  a |  b |  c |
 |----+----+----|
 |  4 |  5 |  6 |
 | 10 | 11 | 12 |

 #+begin_src R :colnames t :var t1=TC t2=TD
 rbind(t1, t2)
 #+end_src
