Try this. I use a ListSelectionListenerand it works for me. I added a listener to the table Model
尝试这个。我使用 aListSelectionListener并且它对我有用。我向表 Model 添加了一个侦听器
jTable.getSelectionModel().addListSelectionListener(new ListSelectionListener() {
@Override
public void valueChanged(ListSelectionEvent event) {
if (jTable.getSelectedRow() > -1) {
// print first column value from selected row
System.out.println(jTable.getValueAt(jTable.getSelectedRow(), 0).toString());
}
}
});
