let readers of view only files chose to hide rows / columns they don't need
Let readers of view only files chose to hide rows / columns they are allowed to view but don't need. This would be handy sharing event info letting different users chose to hide the rows / columns that do not apply to their role. They could each create their custom print out for their particular purposes of the joint project.
The file below is real life example of a Shriner Parade Marshal scheduled work in progress. Everybody needs some of this info. Nobody, including the parade marshal needs all of it. Hiding different combinations of rows and columns gives every parade unit their own customised schedule.
There should be lots of other applications for this change that would lessen the workload of many people. The main point is that it has to be the view that decides what rows and columns he needs to see rather than the author.
