Hi, I'm new in this community and is my first time with jasper. I need to create a table like this: My xml file contains: <addressbook> <person> <name>1. Richiesta ordini di acquisto</name> </person> <person> <name>2. Preparazione dell'ordine</name> </person> <person> <name>3. Approvazione dell'ordine</name> </person> <person> <name>4. Ricezione della merce e/o Servizio</name> </person> <person> <name>5. Gestione reso di merce</name> </person> <person> <name>6. Gestione reclami per merce non conforme</name> </person> <person> <name>7. Attivita' di controllo fisico della merce in magazzino</name> </person> <person> <name>8. Attivita' di controllo contabile carico a magazzino</name> </person> <person> <name>9. Contabilizzazione fatture acquisto</name> </person> <person> <name>10. Autorizzazione al pagamento</name> </person> <person> <name>11. Effettuazione del pagamento</name> </person> <person> <name>12. Gestione fornitori</name> </person> </addressbook> I use a xml dataset into a table component, and use ((net.sf.jasperreports.engine.data.JRXmlDataSource)$P{REPORT_DATA_SOURCE}).subDataSource("/person/name").
