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 |
