I would like a table that groups all the data as you can see here, with an order as you can see made by a correlation on the "ref" :
number
customer
ref
1
1
A
2
1
B
2-1
X
B
2-2
X
B
3
1
C
3-1
X
C
4
2
D
I have already tried many things, the map, the append, the foreach, etc.
Do you have any ideas?
Thank you
