JTable專注於整個行而不是單元格

Question

有什麼辦法可以強制JTable專注於整個行而不是單個單元格嗎？我不是在談論行選擇的亮點，只是關於我想在所關注的行中包含所有單元格的焦點邊界。

UPDATE：

表不可編輯的細胞和刪除行的功能：

「：

public class TableTest { 

    private static void createAndShowGUI() { 

     int rows = 20; 
     int cols = 2; 
     String[] headers = { "Column 1", "Column 2" }; 
     String[][] data = new String[rows][cols]; 

     for (int j = 0; j < rows; j++) 
      for (int k = 0; k < cols; k++) 
       data[j][k] = "item " + (j * cols + k + 1); 

     JTable table = new JTable(); 

     DefaultTableModel tableModel = new DefaultTableModel(data, headers) { 
      // Disable editing of the cells 
      @Override 
      public boolean isCellEditable(int row, int column) { 
       return false; 
      } 
     }; 
     table.setModel(tableModel); 
     table.setShowGrid(false); 
     table.setIntercellSpacing(new Dimension(0,0)); 

     // key binding to remove rows 
     InputMap inputMap = table.getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT); 
     ActionMap actionMap = table.getActionMap(); 
     inputMap.put(KeyStroke.getKeyStroke(KeyEvent.VK_DELETE, 0), "REMOVE"); 
     actionMap.put("REMOVE", new AbstractAction() { 
      @Override 
      public void actionPerformed(ActionEvent e) { 
       int[] rows = table.getSelectedRows();  
       for (int i = rows.length - 1; i >= 0; i--) { 
        tableModel.removeRow(rows[i]); 
       } 
      } 
     }); 

     JFrame f = new JFrame(); 
     f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
     f.getContentPane().add(new JScrollPane(table)); 
     f.setSize(500, 500); 
     f.setVisible(true); 
    } 

    public static void main(String[] args) { 
     javax.swing.SwingUtilities.invokeLater(new Runnable() { 
      public void run() { 
       try { 
        UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); 
        //UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName()); 
       } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException e) {} 
       createAndShowGUI(); 
      } 
     }); 
    } 
} 

上選擇行 」聚焦邊境「焦點邊框「，沒有選擇行：

在Windows LAF

「聚焦邊界」：

我想這個 「邊界集中」 到（可見時），包括該行的所有單元格。

下面是相同的代碼，但我已經添加的@camickr的部分代碼：

public class TableTest { 

    private static void createAndShowGUI() { 

     int rows = 20; 
     int cols = 2; 
     String[] headers = { "Column 1", "Column 2" }; 
     String[][] data = new String[rows][cols]; 

     for (int j = 0; j < rows; j++) 
      for (int k = 0; k < cols; k++) 
       data[j][k] = "item " + (j * cols + k + 1); 


     // ADDED CODE 
     JTable table = new JTable() { 

      private Border outside = new MatteBorder(1, 0, 1, 0, Color.BLACK); 
      private Border inside = new EmptyBorder(0, 1, 0, 1); 
      private Border border = new CompoundBorder(outside, inside); 

      @Override 
      public Component prepareRenderer(TableCellRenderer renderer, int row, int column) { 
       Component c = super.prepareRenderer(renderer, row, column); 
       JComponent jc = (JComponent) c; 
       // Add a border to the selected row 
       if (isRowSelected(row)) jc.setBorder(border); 
       return c; 
      } 
     }; 


     DefaultTableModel tableModel = new DefaultTableModel(data, headers) { 
      // Disable editing of the cells 
      @Override 
      public boolean isCellEditable(int row, int column) { 
       return false; 
      } 
     }; 
     table.setModel(tableModel); 
     table.setShowGrid(false); 
     table.setIntercellSpacing(new Dimension(0,0)); 

     // key binding to remove rows 
     InputMap inputMap = table.getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT); 
     ActionMap actionMap = table.getActionMap(); 
     inputMap.put(KeyStroke.getKeyStroke(KeyEvent.VK_DELETE, 0), "REMOVE"); 
     actionMap.put("REMOVE", new AbstractAction() { 
      @Override 
      public void actionPerformed(ActionEvent e) { 
       int[] rows = table.getSelectedRows();  
       for (int i = rows.length - 1; i >= 0; i--) { 
        tableModel.removeRow(rows[i]); 
       } 
      } 
     }); 

     JFrame f = new JFrame(); 
     f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
     f.getContentPane().add(new JScrollPane(table)); 
     f.setSize(500, 500); 
     f.setVisible(true); 
    } 

    public static void main(String[] args) { 
     javax.swing.SwingUtilities.invokeLater(new Runnable() { 
      public void run() { 
       try { 
        UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); 
        //UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName()); 
       } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException e) {} 
       createAndShowGUI(); 
      } 
     }); 
    } 
} 

這增加了整個行周圍的邊框（但沒有左/右插圖包括所有細胞） 。這不是「焦點邊框/矩形」，它是僅出現在選定行周圍的邊框。當我刪除一行時，所選行被清除並且焦點邊框重新出現。

請注意，我不想隱藏對焦邊界（我知道如何做到這一點），我要保持它的功能一樣，但包括該行，而不是一個小區的所有細胞，當它變得可見。

Answer 1

我只想在整行上顯示FocusBorder。

看看Table Row Rendering。

它顯示了一種方法來在行上放置邊框而不是單個單元格。
