實現搜索textField到jTable

Question

現在我有一個使用KeyReleased事件實現的搜索文本字段，當我開始從「Andrew」開始鍵入例如「An」時，找不到/更新jTable，並且在完成鍵入之後（ caseSensitive）我想找的名字。

所以，我想要的是從這個site實施過濾方法，但我有很大的問題。在下面的實現並刪除「舊」KeyReleased事件後，當我在文本字段「txt_search」中輸入某些內容時，jTable沒有任何反應。

我由IDE（NetBeans的）生成的表的代碼（從自定義代碼面板複製）：

Table_Employee = new javax.swing.JTable(); 

Table_Employee.setModel(new javax.swing.table.DefaultTableModel(
    new Object [][] { 
     {null, null, null, null}, 
     {null, null, null, null}, 
     {null, null, null, null}, 
     {null, null, null, null} 
    }, 
    new String [] { 
     "Title 1", "Title 2", "Title 3", "Title 4" 
    } 
) 
); 

Table_Employee.setToolTipText("Employee info table"); 

Table_Employee.setCursor(new java.awt.Cursor(java.awt.Cursor.DEFAULT_CURSOR)); 

Table_Employee.getTableHeader().setReorderingAllowed(false); 

Table_Employee.addMouseListener(new java.awt.event.MouseAdapter() { 
    public void mouseClicked(java.awt.event.MouseEvent evt) { 
     Table_EmployeeMouseClicked(evt); 
    } 
}); 
Table_Employee.addKeyListener(new java.awt.event.KeyAdapter() { 
    public void keyPressed(java.awt.event.KeyEvent evt) { 
     Table_EmployeeKeyPressed(evt); 
    } 
}); 

jScrollPane1.setViewportView(Table_Employee); 

和添加此在我的面板類，其中表是：

     conn=javaconnect.ConnecrDb(); 
     Update_table(); 
     Fillcombo(); 
     currentDate(); 
     Table_Employee.setAutoCreateRowSorter(true); 
     Table_Employee.setFillsViewportHeight(true); 
     Table_Employee.setSelectionMode(ListSelectionModel.SINGLE_SELECTION); 


     DefaultTableModel model = new DefaultTableModel(); 
     sorter = new TableRowSorter<DefaultTableModel>(model); 
     Table_Employee = new JTable(model); 


     txt_search = new JTextField(); 
     //Whenever filterText changes, invoke newFilter. 
     txt_search.getDocument().addDocumentListener(
       new DocumentListener() { 
        public void changedUpdate(DocumentEvent e) { 
         newFilter(); 
        } 
        public void insertUpdate(DocumentEvent e) { 
         newFilter(); 
        } 
        public void removeUpdate(DocumentEvent e) { 
         newFilter(); 
        } 
       }); 
    } 

    private void newFilter() { 
    RowFilter<DefaultTableModel, Object> rf = null; 
    //If current expression doesn't parse, don't update. 
    try { 
     rf = RowFilter.regexFilter(txt_search.getText(), 0); 
    } catch (java.util.regex.PatternSyntaxException e) { 
     return; 
    } 
    sorter.setRowFilter(rf); 
} 

我真的需要一些幫助，請！這是我的最後一次機會，因爲我真的做了谷歌搜索解決方案，沒有任何改變。
