Hallo, ich beschäftige mich zum ersten Mal mit Jtable und möchte für Zellen mit viel Text eine ScrollPane darstellen.
dazu habe ich einen CellRenderer als auch einen CellEditor implementiert. Leider funktioniert das ganze nicht wie gedacht.
Die JScrollPane wird zwar angezeigt aber sobald ich scrollen möchte verschwindet der Inhalt.
Könnt ihr mir hier weiterhelfen? Danke im Voraus
