如何将JButton添加到行的最后两列列单元格？

Question

我想补充的JButton持续row..How两个单元格可以做到这一点....请帮我...

String[] columnNames= {"EmployeeId","Name", "Designation", "JoiningDate", "DOB","ContactNo","MailId","Password","Edit","Remove"}; 
final DefaultTableModel model1 = new DefaultTableModel(rows, columnNames); 
model1.addColumn("columnNames, data"); 
table3= new JTable(model1); 
table3.getColumn("Edit").setCellEditor(new ButtonEditor(new JCheckBox())); 
table3.getColumn("Remove").setCellEditor(new ButtonEditor(new JCheckBox())); 
table3.setAutoResizeMode(JTable.AUTO_RESIZE_OFF); 
table3.setRowHeight(32); 
JScrollPane pane= new JScrollPane(table3); 
table3.setPreferredScrollableViewportSize(table3.getPreferredSize()); 
JTableHeader header = table3.getTableHeader(); 
header.setBackground(Color.CYAN); 
pane.setBackground(Color.BLACK); 
employeeFrame.add(pane) ; 
table3.getModel();

你需要使用定制单元格呈现（我假设自定义编辑器处理点击事件）。

结帐Using Custom Renderers和Using Other Editors

你可能也想看看CellEditor.isCellEditable设置点击次数来激活按钮

public class MyTatbleEditor { 

    public static void main(String[] args) { 
     new MyTatbleEditor(); 
    } 

    public MyTatbleEditor() { 
     EventQueue.invokeLater(new Runnable() { 
      @Override 
      public void run() { 

       try { 
        UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); 
       } catch (ClassNotFoundException ex) { 
       } catch (InstantiationException ex) { 
       } catch (IllegalAccessException ex) { 
       } catch (UnsupportedLookAndFeelException ex) { 
       } 

       JFrame frame = new JFrame(); 
       frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
       frame.setSize(200, 200); 
       frame.setLocationRelativeTo(null); 
       frame.setLayout(new BorderLayout()); 

       Vector rows = new Vector(); 
       for (int index = 0; index < 10; index++) { 
        Vector data = new Vector(); 
        data.add(new Object()); 
        rows.add(data); 
       } 
       Vector cols = new Vector(); 
       cols.add("One"); 
       DefaultTableModel model = new DefaultTableModel(rows, cols); 

       JTable table = new JTable(model); 

       table.getColumn("One").setCellEditor(new MyTableButtonEditor()); 
       table.getColumn("One").setCellRenderer(new MyTableButtonRenderer()); 

       frame.add(new JScrollPane(table)); 

       frame.setVisible(true); 


      } 
     }); 
    } 

    protected class MyTableButtonEditor extends AbstractCellEditor implements TableCellEditor { 

     private JButton button; 
     private int column; 
     private int row; 

     public MyTableButtonEditor() {

     @Override 
     public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int column) { 
      if (isSelected) { 
       button.requestFocus(); 
      } 
      this.column = column; 
      this.row = row; 
      return button; 
     } 
    } 

    protected class MyTableButtonRenderer implements TableCellRenderer { 

     private JButton button; 

     public MyTableButtonRenderer() { 
      button = new JButton("Click me if you dare"); 
     } 

     @Override

    }
