Arquivo Discussoes de Programacao e Tecnologia Estou tentando remover uma linha da minha tabela, porém não está dando certo, coloquei este código:
public void RemoverLinha()
{
int linhaSelecionada = getJTable().getSelectedRow();
if( linhaSelecionada < 0)
return;
else
RemoverLinha(linhaSelecionada);
}
public void RemoverLinha(int linha)
{
DefaultTableModel modelo = (DefaultTableModel)getJTable().getModel();
modelo.removeRow(linha);
}
Alguém pode me ajudar??
int[] l = table.getSelectedRows();
DefaultTableModel dtm = (DefaultTableModel)table.getModel();
for(int i = (l.length-1); i >= 0; --i)
dtm.removeRow(l[i]);
Acabei de tantar e também não está dando certo…
