Un report vendite raggruppato in poche righe
La stessa API in Delphi, C++ Builder e C#: un'intestazione per regione, una riga per vendita e un subtotale per regione, salvato come PDF, XLSX e CSV.
Un report fluente su una sorgente JSON: un gruppo per regione con un subtotale, salvato come PDF, XLSX e CSV.
