Hi, Carsten,
Yes, it's really neat.
I just realized, though, that there *is* an equally clean way to
generate such tables in OOo Calc (which the Org spreadsheet has all
but replaced for my needs):
- Place 1 in cell B1. Drag across to get 1-10 in cells B1:K1.
- Place 1 in cell A2. Drag down to get 1-10 in cells A2:A11.
- In cell B2, type the formula =B1:K1*A2:A11. Do NOT press Enter,
press Ctrl-Shift-Enter (or Cmd-Shift-Enter on Mac) to make it an
"array formula" (it presents as {=B1:K1*A2:A11}).
- Hey presto, the table is filled.
Yours,
Christian

Hi Christian,
thanks for the great example! I guess this is really something
Org has over other spreadsheets. No copy-and-paste-with-modification,

Hi,
Row formulas are great! I've missed this, but learned to work around it, since
I I just assumed that if you hadn't already done it, it was not a reasonable
thing to ask for.
Testing... So now we can simply do e.g.:
#+CAPTION: A multiplication table
| | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
|----+---+---+---+---+---+---+---+---+---+----|
| 1 | | | | | | | | | | |
| 2 | | | | | | | | | | |
| 3 | | | | | | | | | | |

| 5 | | | | | | | | | | |
| 6 | | | | | | | | | | |
| 7 | | | | | | | | | | |
| 8 | | | | | | | | | | |
| 9 | | | | | | | | | | |
| 10 | | | | | | | | | | |
#+TBLFM: @2$2..@11$11=@1*$1
C-c C-c...and hey presto:
#+CAPTION: A multiplication table
| | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
|----+----+----+----+----+----+----+----+----+----+-----|

Hi everyone,
A frequently requested feature for tables has been to
be able to define row formulas in a way similar to column
formulas. The patch below allows things like
@3=
@2$2..@5$7=
@I$2..@II$4=
as the left hand side for table formulas in order to
write a formula that is valid for an entire column or
for a rectangular section in a table.
Note that in contrast to column formulas, @3= will not
automatically skip a "header column" or field formulas in the
same row. In fact, making both a range formula and a field
point to the same field is forbidden and throws an error.
So to have a formula apply to all but the first column, use
something like this:
@3$2..@3$8=....
Testing is welcome, but I am confident that this works
pretty well.
Bastien, please let me know if you want to have this integrated
before the release, then I will do so.
