已选择SET行

Question

我试图设置从JTable中选择的行，我获取并比较从我的DB中收到的所有数据，然后在比较数据时，如果数据存在，它必须设置所选的行。

我已经尝试了几个函数，如setSelectionModel或setSelectionInterval，但它们都没有设置选中具有必须选择的值的行。

有什么建议吗？

这里有一些代码。。。。但不确定它是否会有帮助。。。但这是我在网上读到的。。。根本没有选择我想要的行。。。leerTripulantesVuelo带回了一个Tripulantes数组，这就是我在列表中选择那个Tripulante的过程。

ModeloTablaTripulantes tablaPil = new ModeloTablaTripulantes();
tablaPilotos.setModel(tablaPil);
tablaPilotos.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
ArrayList<Tripulante> trip = new ArrayList();
    String tipoPersona = "t";
    String numVuelo = numeroVueloListaTripulantes.getText();
    try {
        trip = Aerolinea.leerTripulantesVuelo(numVuelo);
        for (Tripulante t: trip){
            for(int i =0; i<tablaPil.getRowCount();i++){
                if (tablaPil.getValueAt(i, 0).equals(t.getCedula())){
                    tablaPilotos.getSelectionModel().setSelectionInterval(i, i);
                }
            }
        }
    } catch (BDException ex) {
        ex.printStackTrace();
    }

Answer 1

下面是一个完整的示例，用于选择表中的第二行。我使用NetBeans，所以不关心ui的代码。jButton1ActionPerformed中的代码包含jTable1.getSelectionModel().setSelectionInterval(row, row)，它正是我所期望的——选择行
你确定你的程序运行到setSelectionInterval()吗？也许字符串末尾包含空格。调试应该有助于找到答案。
