Hi all,
I almost have a squeaky clean solution to this thanks to the hint provided
by someone on emacs.SE ( http://emacs.stackexchange.com/a/22215/115 ).
But in the process, I seem to have stumbled upon a bug.. the buffer local
value of variables are not respected at the time of exports.
To demonstrate that, please evaluate the elisp code at the end of this
email and do C-c C-e h o on the below MWE of org file:
As the buffer local value of modi/org-table-enable-buffer-wide-recalculation
var is nil, that table does not get recalculated when saving. But it always
gets recalculated when exporting (e.g. using C-c C-e h o).
