Why do you think so?

I second Nick: your proposition is wrong; it can't work like that.

Now, maybe you're hit by a feature here: when setting
`org-hide-emphasis-markers' to t, some `@' disappear from the formula (as you
see them, while they're there: enable visible-mode and check it!).

Is this what happens to you?

That's a feature...

Best regards,
  Seb

Why would @ disappear with `org-hide-emphasis-markers' set to t?

They should not visually disappear, but they do.

Consider the following formula line:

|---+---|
|   |   |
|---+---|
#+TBLFM: @1$1=vsum(@-I..@-II)

It becomes this:

#+TBLFM: 1$1=vsum(-I..@-II)
         ^        ^

when `org-hide-emphasis-markers' is turned on.

Best regards,
  Seb

No... chances are that it comes from your configuration.
Please always assume it does first, then provide a recipe
if it's with emacs -Q.  Thanks!

I heard from Frank privately: there was another error in the formula and
he thought he had to get rid of the second @ to make it work. That's not
correct: the @III form works fine

However, the formula without the @ in front of III *also* works in this
case.  I don't know whether that's an accident or intended behavior.

Yes, it does. I still had the following code, from when `@' was unofficially
supported in Beamer to render alert calls:

--8<---------------cut here---------------start------------->8---
  (defface my/org-alert-face
    '((t (:weight bold :foreground "black" :foreground "#FF0000")))
    "Face used to display alert'ed items.")

  (add-to-list 'org-emphasis-alist
               '("@" my/org-alert-face "<span class=\"alert\">" "</span>"))

  (add-to-list 'org-export-latex-emphasis-alist
               '("@" "\\alert{%s}" nil))
--8<---------------cut here---------------end--------------->8---

Without that, the problem disappears.

Sorry for the noise.

Best regards,
  Seb

FWIW, I don't know neither... maybe Carsten can tell.
