Org-mode Table, No export Latex column

Question

Is there a way to have a column of a table not export, specifically in latex? I want to have an extra column for personal notes but when I export I don't want the table there.

Answer 1

Following this answer, I was able to get this to work by prepending

#+LATEX_HEADER: \usepackage{array}
#+LATEX_HEADER: \newcolumntype{H}{>{\setbox0=\hbox\bgroup}c<{\egroup}@{}}
#+ATTR_LATEX: :align rrH
|Good column| another good column|column to hide in export|
| data      | data               | notes                  |

to the table. This creates a new column type H for a hidden column and then uses that type in the align attribute. So in the above example, it would hide the 3rd column.
