Every so often I prepare a table and later decide to remove one column. Editing the data is annoying because it is sorted by rows, and also because I sometimes find that the result of removing the columns is worse and have to go back and un-do it.

Is there a column type "skip" or "null" or "do not print" - something which can silently passes over the column data without printing it? This would make it much easier to try removing a column and see how it looks.


This obviously can't remove rules between columns.

  a & b & c \\

  a & c \\
