I have a pivot table like this showing people going from one telco operator to another one.
RECEIVERS/GIVERS
ORANGE
VODAFONE
SFR
Totals outgoing
ORANGE
-
5

8
VODAFONE
2
-
4
6
SFR
5
6
-
11
Totals incoming
7
11
7
25
When I have the same operator, I have a '-' in my table which is normal but i would like to show instead of the ' - ', the balance : Incoming - Outgoing.
I would like to have this :
RECEIVERS/GIVERS
ORANGE
VODAFONE
SFR
Totals outgoing

- 1

VODAFONE
2
5
4

SFR
5

-4
11
Totals incoming
7
11

25
