将行添加到jTable

Question

I'm doing an exercice about java swing, now it's time to add rows from a database to the jTable, I know that the method to do this is "addRow()" but netBeans doesn't suggest it to my and underline the line as a mistake.

Is necesary to import something before, or does someone know what I'm doing bad?

thanks.

Answer 1

addRow is an instance method of DefaultTableModel rather than JTable . Set the model for the JTable and then add to it:

DefaultTableModel model = new DefaultTableModel();
JTable table = new JTable(model);
model.setColumnIdentifiers(new String[] { "Column 1", "Column 2"});
model.addRow(new String[] { "foo", "bar" });
