JTable in JTabbedPane_TabPanel

-1

我做了一個小例子。我有一個帶有兩個選項卡的jTabbedPane。在TabPanel2中按下一個按鈕後，一張桌子就會關閉。但是表沒有出現。請幫幫我。謝謝。JTable in JTabbedPane_TabPanel

import javax.swing.table.DefaultTableModel; 

public class test extends JFrame { 
    private JButton jButton1 = new JButton(); 
    private JTabbedPane jTabbedPane1 = new JTabbedPane(); 
    private JPanel jTabbedPane1TabPanel1 = new JPanel(null, true); 
    private JPanel jTabbedPane1TabPanel2 = new JPanel(null, true); 
    private JButton jButton2 = new JButton(); 

    public void jButton2_ActionPerformed(ActionEvent evt) { 
    DefaultTableModel tableModel = new DefaultTableModel(0,2); 
    tableModel.addRow(new Object[] {"string1","string2"}); 
    JTable table1 = new JTable(tableModel); 
    jTabbedPane1TabPanel2.add(table1); 
    } 
}

歡迎來到SO。請參考[tour]（https://stackoverflow.com/tour），閱讀[如何提問]（https://stackoverflow.com/questions/how-to-ask），並編輯您的問題以包含[最小，完整和可驗證示例]（https://stackoverflow.com/help/mcve）。在你的具體情況下，你應該顯示更多的代碼。給整個班級刪除所有不相關的行，包括JFrame實例化的主要部分。在那裏可以找到許多MCVE。但是很可能你的jTabbedPane_1TabPanel1從未被添加到某個顯示*的*容器中。 – jeff6times7
