hi again,
I haven't found how to solve this, short of removing the evaluation of
`user-error' from the org-table.el code, or stuffing my TBLFM line with
field formulas.
a very simple use case: three columns: the date, a daily measurement,
and a running 4-days average.
| date | measure | running avg ||-------+---------+-------------||
01-27 | 604 | skipped || 01-28 | 314 | skipped || 01-29
| 636 | skipped || 01-30 | 305 | skipped || 01-31 |
760 | skipped || 02-01 | 531 | skipped || 02-02 | 331 |
nil || 02-03 | 77 | nil || 02-04 | 621 |
nil || 02-05 | 406 | nil || 02-06 | 621 |
nil || 02-07 | 975 | nil || 02-08 | 252 |
nil || 02-09 | 794 | nil || 02-10 | 36 |
nil |#+TBLFM: $3='(unless (> @# 7) "skipped") #+TBLFM: $3='(when
(> @# 7) (/ (apply #'+ '(@-6$2..$2)) 7.0));N%0.2f #+TBLFM: $3='(/ (apply
#'+ '(@-6$2..$2))
7.0);N%0.2f::@2$3='(string)::@3$3='(string)::@4$3='(string)::@5$3='(string)::@6$3='(string)::@7$3='(string)
the first TBLFM shows you which cells I'm skipping, that is, where I'm
not applying the @-6 reference. the status of the table results from
evaluation of that TBLFM line.
the second TBLFM line skips all @-6 references, but still fails with the
message
user-error: Row descriptor -6 leads outside table
the third TBLFM line "solves" the problem, in one of the ugliestests ways.
how would you people approach this?

Hi,
I need some help understanding how to use org-mode/org-table for
references leading outside my table.
I have a series of daily figures, and I am computing the series of
running sums. column one is the daily data, column two is the running
sum of the preceding 14 values from column 1.

problem is the @-13$1 reference in the function for the second column:
it hits a software-generated "user-error: Row descriptor -13 leads
outside table".
this happens even if the formula says (if (> @# 13) (apply '+
'(@-13$1..$1)) 0), that is, even if the formula is not evaluated on
the cells where the reference does indeed lead out of the table.
this happens around line 2809 of org-table.el, inside org-table--row-type
I've tried to catch the user-error with a `condition-case', but even
there, the error seems to happen before evaluation.
I've replaced the `(user-error)' function with a `nil', and it works
for me, but that's a very rough measure I'm afraid.
