Aprenda a fazer corretamente um TableModel. Se for para fazer um que é um equivalente piorado do DefaultTableModel, aí é melhor nem fazer. No link da minha assinatura tem diversos tutoriais, alguns bem detalhados.

Bom dia

Obrigado pela honra ViniGodoy ,
elitoncampos espero que tenha ajudado, quando tiver craque no “table model” tenta usar este framework do Mark Vasconcelos :
towel project > http://markytechs.wordpress.com/towel-project/
download > https://github.com/MarkyVasconcelos/Towel/downloads

Nele contém á classe ObjectTableModel:
ObjectTableModel > http://markytechs.wordpress.com/2009/05/29/objecttablemodel/
A classe ObjectTableModel faz uso de reflection e annotations muito bom para quem quer produtividade na criação de tablemodel.

Faloww
