Hi,

I just notice a funny row-shift effect, having a table with a field
calculated by vsum.


| Nr. | value |
|-----+-------|
|   1 |     5 |
|   2 |     5 |
|   3 |     5 |
|   4 |     5 |
|   5 |     5 |
|   6 |     5 |
|-----+-------|
| Sum |    30 |
#+TBLFM: @8$2=vsum(@2..@7)

now shift (sort) the rows by using M-arrowup and M-arrowdown


| Nr. | value |
|-----+-------|
|   1 |     5 |
|   6 |     5 |
|   5 |     5 |
|   3 |     5 |
|   4 |     5 |
|   2 |     5 |
|-----+-------|
| Sum |    10 |
#+TBLFM: @8$2=vsum(@2..@3)

Check, the #+TBLM:-line changed too! This might be desired sometimes
but might also trouble people if they do not give careful attention.

I know someone could do

| Nr. | value |
|-----+-------|
|   1 |     5 |
|   6 |     5 |
|   5 |     5 |
|   3 |     5 |
|   4 |     5 |
|   2 |     5 |
|-----+-------|
| Sum |    30 |
#+TBLFM: @8$2=vsum(@I..@II)

But still I feel that people can too easily trap into wrong calculus.

One solution, I could see is then whenever forms change
"automagically" highlight this changes within the TBFM line, e.g.,  by
a change of the background color in a similar way like matching
parenthesis. That might help to make people more aware of it and shows
which equations are affected by the current operation.


All the best

Torsten
