It appears that displaying multiple records of the group in a single row can only be done using PHP where I am rather newbe.
How can PHPR be used for this, I presume in the event pages before processing.
Let's say, I have a table
field1 field2 field3
1 1 a
2 1 b
3 2 c
4 3 d
As a result, I'd like to receive
field1 field2 field3 field31
1 1 a b
2 2 c
3 3 d
Could somebody help with a sample code?
