Re: Table rows and ranges as LHS of formulas

[Christian Moe <mail@christianmoe.com>]

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 |   |   |   |   |   |   |   |   |   |    |
|  4 |   |   |   |   |   |   |   |   |   |    |
|  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 |
|----+----+----+----+----+----+----+----+----+----+-----|
|  1 |  1 |  2 |  3 |  4 |  5 |  6 |  7 |  8 |  9 |  10 |
|  2 |  2 |  4 |  6 |  8 | 10 | 12 | 14 | 16 | 18 |  20 |
|  3 |  3 |  6 |  9 | 12 | 15 | 18 | 21 | 24 | 27 |  30 |
|  4 |  4 |  8 | 12 | 16 | 20 | 24 | 28 | 32 | 36 |  40 |
|  5 |  5 | 10 | 15 | 20 | 25 | 30 | 35 | 40 | 45 |  50 |
|  6 |  6 | 12 | 18 | 24 | 30 | 36 | 42 | 48 | 54 |  60 |
|  7 |  7 | 14 | 21 | 28 | 35 | 42 | 49 | 56 | 63 |  70 |
|  8 |  8 | 16 | 24 | 32 | 40 | 48 | 56 | 64 | 72 |  80 |
|  9 |  9 | 18 | 27 | 36 | 45 | 54 | 63 | 72 | 81 |  90 |
| 10 | 10 | 20 | 30 | 40 | 50 | 60 | 70 | 80 | 90 | 100 |
#+TBLFM: @2$2..@11$11=@1*$1
