Hi, in order to calculate the average with some invalid column, I
managed to write a short elisp script. You can see the difference
between the `0' and the `-' in this table:
| ! | P1 | P2 | P3 | P4 | P5 | Average |
| # | 3.6 | 4.0 | 4.8 | 0 | 4.7 | 3.42 |
| # | 5.0 | 3.3 | - | 4.7 | 4.0 | 4.25 |
#+TBLFM: $7='(let ((data '("$P1" "$P2" "$P3" "$P4" "$P5"))
(n 0)
(total 0))
(while data
(unless (string= (car data) "-")
(setq total
(+ total (string-to-number (car data))))
(setq n (1+ n)))
(setq data (cdr data)))
(/ total n));%.2f
It is reformatted to be more readable, since one cannot put a
multi-line expression in #+TBLFM.
I admit it is really painful to do this. I want to know if anyone
knows how I can simplify this a bit, or if there is a short cut to do
this. I'm not familiar with the internal implementation of org table,
but is there any possibility to make it as a built-in function that I
can put it somewhere in the same org file so that I can easily do some
thing like mymean($P1..$P5)?
Thanks,
Xiao-Yong

In the following table, the last row gives the number of empty cells
following the last nonempty cell in each column (except the first column
of course). I would like to create a TBLFM formula that does this
calculation for me automatically. Some time ago I tried using
org-lookup-last and org-lookup-all for this, but I never got it to work.
Any ideas/solutions?

#+TBLFM: @>$<<..@>$> = find(rev(@I..@II), 1) - 1; E
Note that I moved the header separator line.
When the last non-empty cell is not limited to be always 1 it gets a
bit more complicated:
#+TBLFM: @>$<<..@>$> = '(position-if-not (lambda (x) (equal x ""))
(reverse '(@I..@II))); E
