See (info "(org) var") in particular the section on "Indexable variable
values".
Additionally, an empty index, or the single character ‘*’, are both
interpreted to mean the entire range and as such are equivalent to
‘0:-1’, as shown in the following example in which the entire first
column is referenced.
#+NAME: example-table
| 1 | a |
| 2 | b |
| 3 | c |
| 4 | d |
#+BEGIN_SRC emacs-lisp :var data=example-table[,0]
data
#+END_SRC
#+RESULTS:
| 1 | 2 | 3 | 4 |
