First things first: Flexcel is a great piece of software. I love it. I had so many different Excel libs befrore nothing even comes near this great and platform idependant library!
I now want o use it as report generator in my new project (Linux/WIndows/OSX), works well including directly generating PDFs. What I did not find our by now is:
Can I feed the report with a single dataset that has repeating contents for groups, for example:
MillerBeer12
MillerBeer17
MillerLemonade12
SmithLemonade18
JonesLemonade19
Or do I have to split such a dataset into several sets and define relationships?
Well, it depends on what you want to do with the data. If you want to dump it "as is" of course you can, and it will look exactly like the data in your example.
If you want to group the report into something like:
Beer
Miller 12
Miller 17
Lemanoade
Miller 12
Smith 18
Jones 19
Then you have indeed to create a master-detail report to tell Flexel how it should be grouped. Should it group by kind (lemonade, beer) or by name (miller, smith, jones)? Or maybe group by both?
