Arquivo Discussoes de Programacao e Tecnologia E aí pessoal blz.
seguinte.Por que quando eu faço isso no frame principal funciona mas quando eu mando fazer de outro frame não.
javax.swing.table.DefaultTableModel modelo = new javax.swing.table.DefaultTableModel(dadosAgrup,new Object [] {"Intervalo", "Frequência", "FA", "FR", "FRA", "Média"});
Tabela.setModel(modelo);
como faço para driblar esse problema.
Cara, não tem como você postar o código que está usando? Normalmente apenas isso já funciona, não é muito comum ocorrer isso.
Abraços.
ta aí:
Foi feito no netbeans.
