I am using columnview table now to get some summaries of worked hours and
quantity balance as well. This is one example showing a quantity of quoted
computers and the real sold quantity:
| | ITEM | Quotation | Sold |
|---+-------------------------+-----------+------+
| | ** Computers | 10 | 7 |
|---+-------------------------+-----------+------+
Is there any way to automatically insert a fórmula in a third column? For
example, I could insert a "Difference" column and make Sold - Quotation and get
this result:
| | ITEM | Quotation | Sold | Difference |
|---+-------------------------+-----------+------+------------|
| | ** Computers | 10 | 7 | -3 |
|---+-------------------------+-----------+------+------------|
So I could change the column defintion from:
:COLUMNS: %50ITEM %10Quoted(Quotation){+} %10Sold(Sold){+}
To:
:COLUMNS: %50ITEM %10Quoted(Quotation){+} %10Sold(Sold){+}
%10Sold-Quoted(Difference)
Maybe I am going too far with tables and columns view and the developers did
not intend this kind of feature because of complexity.
But I think this would be a great feature.

Flávio

org-collector is useful when you want to perform calculations on
properties *before* they are entered into a columnview type table.
Using org-collector a dblock like the following should work.
#+BEGIN: propview :cols (ITEM Quoted Sold (- Sold Quoted))
#+END:
The downside of org-collector is that it is not really part of org-mode,
and it doesn't have many of the nice features of columnview tables, like
the specification of column titles. You can grab a copy of
org-collector.el from here
