关于 Java/Eclipse/Windowbuilder 未获取值的奇怪错误？

Question

我有一个非常奇怪的问题.. "getValueAt" 方法 return 值与频率一不同 - 它 return 为空。我不明白为什么把table当作一个方法在里面。有人知道为什么吗？

JButton btnAdd = new JButton("Add ");
    btnAdd.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e) {
            lblWeSuggestThe.setText(woooord);;
            id.add(table_1.getValueAt(0,0)+"");
            forename.add(table_1.getValueAt(0,1)+"");
            surname.add(table_1.getValueAt(0,2)+"");
            address.add(table_1.getValueAt(0,3)+"");
            frequency.add(table_1.getValueAt(0,4)+"");
            JLabel lblWeSuggestThe = new JLabel("We suggest the use of ID " + (id.size() + 1) + ".");
                try {
                    FileWriter fw = new FileWriter ("southbank.csv", true);
                    fw.write("\n" + table_1.getValueAt(0,0) + "," +table_1.getValueAt(0,1) + "," +table_1.getValueAt(0,2) + "," +table_1.getValueAt(0,3) + "," +table_1.getValueAt(0,4) +"");
                fw.close();
                    } catch (IOException e1) {

                        e1.printStackTrace();
                    }

                }
            });

对于那些将来遇到此问题的人，您必须在输入最终值后按回车键，或者单击与您输入的数据不同的列，因为数据不会被设置。

例如，在输入第五个也是最后一个条目后单击第四个条目。
