Here is a straightforward spreadsheet:


* Test org-mode spreadsheet for cash books


|   | Name             |           Cash |
|---+------------------+----------------|
| _ |                  |    cashforward |
|   |                  |          68000 |
| _ |                  |       cashtake |
|   | cash takings     |           2340 |
| _ |                  |       cashbank |
|   | moved to bank    |           2000 |
|---+------------------+----------------|
| _ |                  |           cash |
| # | subtotal         |          68340 |
|---+------------------+----------------|
|   | emp1             |            315 |
|   | emp2             |            289 |
|   |                  |              0 |
|   |                  |              0 |
|---+------------------+----------------|
| _ |                  |          wages |
| # | total wages      |            604 |
|---+------------------+----------------|
| _ |                  | cashafterwages |
| # | Cash After Wages |          67736 |
|---+------------------+----------------|
#+TBLFM: $cash=$cashforward+$cashtake-$cashbank::$cashafterwages=$cash-$wages::$wages=vsum(@10$3..@13$3)

My questions are:

Can one not actually name a specific cell? Or must the name itself be
stored above or below the cell?

The wages field : how to generalise this to allow for rows to be
added/deleted in the emp1,emp2 block?

Or is there a totally better way to do this? I didnt see a way for all
fields to auto calculate when a certain field was changed. One has to
tab over the "#" in the left hand column. Or?

If you can suggest a neater approach please do - this is my first
attempt at an org-mode spreadsheet.

Oh yes, can one change the enter mode so that the field only edits if
you press enter first? And then it preselects the previous contents so a
single key other than cursor keys will wipe the previous contents?
Currently if I type "5" in the wages field above then, depending where
the cursor is, I get (for example) 6504.

C-c'
gives you a nice interface to the table formulas, making names
almost obsolete

$wages = vsum(@-I..@-II)
will do the trick (sum between hlines)
apart from that, if you add rows using M-S-down your formulas will be
adjusted automatically.

As the manual says: C-u C-c *
you might also want to look at the Tbl menu

The interface is already outstandingly smart: Try moving with the TAB
from one field to another or use enter to stay inside the column. You
will notice that the requested features are already present. Maybe, also
try another couple of spreadsheets :-)

I dont see how - names make the formula readable.  How does this buffer
makes anything much easier in terms of cell referencing?

Thats nice - thanks.

That is not the same thing as auto recalculation as in excel or similar
: you must manually invoke it. This is easily forgotten (well by me :-;)

If I tab to a field above and press enter a new row appears. It is bound
to org-return. (Latest version). Also there is no preselection of the cell
contents so if I type "8" when I have tabbed to the "cashbank" field
above then I get "| 8 2040 |".

Fortunately, there is _no_ auto-recalculation, it would slow down
things significantly on large tables with complex formulas.

tab into the field and start writing... believe me, it works (org 6.06b
and all versions I used since the tables were introduced.)

Well, clearly one would be able to turn it off in the case of excessive
load. In my case its unfortunate, rather than fortunate, since the
spreadsheets I have (or want to convert) are small and there is
negligible slowdown. To have to remember to refresh the entire
spreadsheet is a burden - not a large one I agree, but one which if
forgotten could lead to catastrophic financial reports :-;

As I said above, when I tab in and start writing it adds to the existing
text. I do believe it might be different for you, but believe me, it
does not for me...

6.06b

Possibly it is some other mode interfering or we are at cross meanings
here - the cashbank example explains the scenario reasonably well I
think (or rather hope:-;).

Hi Richard,

how about this code (can even go into .emacs):

(run-with-idle-timer 1.0 'repeat
    (lambda ()
      (and (eq major-mode 'org-mode)
	  (org-at-table-p)
	  (org-table-recalculate 'all))))


This will recalculate each time you are idle for more than 1 second  
with cursor inside the table.

This may get you into trouble when you have a formula that produces  
and error, in which case you can protect the call with a condition- 
case, or you can write yourself a function that does turn this feature  
on and off.

What is the setting of org-table-auto-blank-field ?

If it is t and the feature Thomas describes does not work, you have  
indeed got interference from some other  package.
