Re: [O] Table refuses to forget cell formula which once overrode a column formula

[Ruy Exel]

Thanks for your reply.  I now understand and I also agree it is a good
solution.

Best,
Ruy

The property is here to prevent evaluation of a column formula on
a given field. It doesn't override anything.

This is what happens already. The property prevents useless
computations.

Here's what I do in such cases (I'm assuming that the change exists in master, 
either because it
was applied there in the first place, or after a merge with maint):

- update my git repo: git checkout master; git remote update; git rebase
- check recent history: git log -20 --oneline
- find the commit of interest - in this case

   6059c3a05 org-table: Clean left-over `:org-untouchable' property

- show the commit: git show 6059c3a05

HTH.

Hi Nicolas,

Thanks very much.  Just out of curiosity I'd be interested in understanding
how did you do it.  My (non expert) impression is that using properties to
override column formulas isn't a good idea.  It seems to me it would be
more natural to apply cell formulas AFTER all column formulas were applied,
so that each cell would be simply the output of the formula defining it.

Best,
Ruy
