Re: [O] Deletion immediately after insertion should leave org-mode tables unaltered but it doesn't

[Ruy Exel]

Hi Nicolas,

This is indeed a good idea as it mimics the creation of a row in emacs text-mode with "C-o". 

Best wishes,

Ruy

The deletion is triggered by pressing the <LEFT> arrow. Your suggestion
would make the point move right. This is not optimal either.

Maybe the other way is better. Since column creation is triggered by
pressing <RIGHT> arrow, we might create it to the right of the current
column, and point would move into it.

WDYT?
