In (info "(org) Editing and debugging formulas"):
`<TAB> (`org-table-fedit-lisp-indent')'
Pretty-print or indent Lisp formula at point. When in a line
containing a Lisp formula, format the formula according to
Emacs Lisp rules. Another <TAB> collapses the formula back
again. In the open formula, <TAB> re-indents just like in
Emacs Lisp mode.
What does the `open formula' mean? I've searched the Org manual/FAQ and web,
and I only found this:
http://docs.oasis-open.org/office/v1.2/os/OpenDocument-v1.2-os-part2.html
But it seems that the `open formula' doesn't mean this.
