    I like what’s in OP. I will copy for sure. For the record, I’ve found myself defining a function and using org-sbe instead, as often I want the data in the same table :

    Here’s an example with a python formula, but you can use whatever

    #+NAME: sampformula
    #+BEGIN_SRC python :var angle=90 :var r=2 :exports none
    from math import radians, cos
    result = r*cos(radians(angle))
    return result
    #+END_SRC
    
    | angle |  r |             x |
    |-------+----+---------------|
    |    30 | 10 | 8.66025403784 |
    |    45 | 10 | 7.07106781187 |
    |    60 | 10 |           5.0 |
    #+TBLFM: $3='(org-sbe "sampformula" (angle $1) (r $2))
