Unexpected behavior when editing table formulas in dedicated buffer

[Panagiotis Vlantis]

Hi,

I noticed that when editing table formulas in a separate buffer (using 
org-table-edit-formulas) which contain assignments to named fields whose 
name includes underscores (e.g., $foo_bar), these lines are not included 
in the generated #+TBLFM directive. This is probably because the regular 
expression in org-table-fedit-finish does not expect named fields with 
underscores although the manual indicates that they are allowed 
characters (Tables > The Spreadsheet > Advances Features).

Going by the manual, it would appear that this

"^\\(@[-+I<>0-9.$@]+\\|@?[0-9]+\\|\\$\\([a-zA-Z0-9]+\\|[<>]+\\)\\) *= 
*\\(.*\\(\n[ \t]+.*$\\)*\\)"

should be replaced by this

"^\\(@[-+I<>0-9.$@]+\\|@?[0-9]+\\|\\$\\([a-zA-Z0-9][a-zA-Z0-9_]*\\|[<>]+\\)\\) 
*= *\\(.*\\(\n[ \t]+.*$\\)*\\)"

in the body of org-table-fedit-finish.
