合併兩個行篩選了一個JTable

Question

這裏是我的表中的一些代碼

AthleteID.setLocation(200,120); //Sets the location 
    AthleteID.setSize(150,26); //Sets the size 
    AthleteID.setText("Athlete ID Search:"); 
    firstPanel.add(AthleteID); //Adds it to the panel 

    ForeName.setLocation(731,120); //Sets the location 
    ForeName.setSize(150,26); //Sets the size 
    ForeName.setText("Athlete Name Search:"); 
    firstPanel.add(ForeName); //Adds it to the panel 

    String[] aHeaders = {"Athlete ID","Forename","Surname","On The Team"}; 

    model = new DefaultTableModel(a.compTableData,aHeaders) 
    { 
     @Override 
     public boolean isCellEditable(int row, int column) 
     { 
      return false; 
     } 
    }; 
    athTable = new JTable(model); 
    athTable.setAutoCreateRowSorter(true); 
    athTable.setRowHeight(20); 

    myScrollTable = new JScrollPane(athTable); 
    myScrollTable.setSize(1082,600); 
    myScrollTable.setLocation(200,145); 
    System.out.println("Creating compare table"); 

    sorter = new TableRowSorter(athTable.getModel()); 
    List sortKeys = new ArrayList(); 
    sortKeys.add(new RowSorter.SortKey(3, SortOrder.DESCENDING)); 
    sorter.setSortKeys(sortKeys); 
    //////// 
    sorter.setRowFilter 
    (
     new RowFilter<TableModel, Integer>() 
      { 
      @Override 
      public boolean include(RowFilter.Entry<? extends TableModel, ? extends Integer> entry) 
       { 
        boolean included = true; 
        Object cellValue = entry.getModel().getValueAt(entry.getIdentifier(), 0); 
        if (cellValue == null || cellValue.toString().trim().isEmpty()) 
        { 
         included = false; 
        } 
        return included; 
       } 
      } 
    ); 
    ///////// 
    sorter.setComparator(0, new AlphanumComparator()); 

    athTable.setRowSorter(sorter); 

    filterAthID = new JTextField(10); 
    filterAthID.setSize(425,26); 
    filterAthID.setLocation(306,120); 
    filterAthID.setToolTipText("Enter Athlete ID"); 
    firstPanel.add(filterAthID); 

    filterForeName = new JTextField(10); 
    filterForeName.setSize(425,26); 
    filterForeName.setLocation(857,120); 
    filterForeName.setToolTipText("Enter Athlete Name"); 
    firstPanel.add(filterForeName); 

    btnBack.setLocation(0,120); 
    btnBack.setSize(200,50); 
    btnBack.setText("Back"); 
    btnBack.addActionListener(this); 
    firstPanel.add(btnBack); 

    Document doc = filterAthID.getDocument(); 
    DocumentListener listener = new DocumentListener() { 

     @Override 
     public void insertUpdate(DocumentEvent e) 
     { 
      newFilter(); 
     } 

     @Override 
     public void removeUpdate(DocumentEvent e) 
     { 
      newFilter(); 
     } 

     @Override 
     public void changedUpdate(DocumentEvent e) 
     { 
      newFilter(); 
     } 
    }; 
    doc.addDocumentListener(listener); 

    Document docb = filterForeName.getDocument(); 
    DocumentListener listenerb = new DocumentListener() { 

     @Override 
     public void insertUpdate(DocumentEvent e) 
     { 
      newFilter(); 
     } 

     @Override 
     public void removeUpdate(DocumentEvent e) 
     { 
      newFilter(); 
     } 

     @Override 
     public void changedUpdate(DocumentEvent e) 
     { 
      newFilter(); 
     } 
    }; 
    docb.addDocumentListener(listenerb); 

    for(int i=0;i<a.nextPosition;i++) 
    { 
     System.out.println(athTable.getModel().getValueAt(i,0)); 
    } 

    firstPanel.add(myScrollTable); 
} 

private void newFilter() 
{ 
    RowFilter rf = null; 
    try 
    { 
     List<RowFilter<Object,Object>> filters = new ArrayList<RowFilter<Object,Object>>(2); 
     filters.add(RowFilter.regexFilter("(?i)"+filterAthID.getText(), 0)); 
     filters.add(RowFilter.regexFilter("(?i)"+filterForeName.getText(), 1)); 
     rf = RowFilter.andFilter(filters); 
    } 
    catch (java.util.regex.PatternSyntaxException e) 
    { 
     return; 
    } 
    sorter.setRowFilter(rf); 
} 

的問題是，當我在filterAthID或filterForeName搜索的東西，然後刪除我在尋找空白行的內容將出現在我的代碼。

sorter.setRowFilter 
    (
     new RowFilter<TableModel, Integer>() 
      { 
      @Override 
      public boolean include(RowFilter.Entry<? extends TableModel, ? extends Integer> entry) 
       { 
        boolean included = true; 
        Object cellValue = entry.getModel().getValueAt(entry.getIdentifier(), 0); 
        if (cellValue == null || cellValue.toString().trim().isEmpty()) 
        { 
         included = false; 
        } 
        return included; 
       } 
      } 
    ); 

我已經使用此代碼刪除任何空白行，但在我清空我的搜索後，這似乎停止工作。有人可以幫助解決這個問題嗎？

合併兩個行過濾器一個JTable

您可以將多個過濾器合二爲一。此示例使用「和」 fileter，但你也可以使用「或」過濾器：

List<RowFilter<Object,Object>> filters = new ArrayList<RowFilter<Object,Object>>(2); 
filters.add(RowFilter.regexFilter(filterText.getText(), 0)); 
filters.add(RowFilter.regexFilter(filterText.getText(), 1)); 
rf = RowFilter.andFilter(filters); 

這個例子是基於從Swing教程演示Sorting and Filtering。
