如何在表格单元格中添加复选框和组合框？

Question

我正在创建一个包含表格和一些按钮的窗体。

一张图片胜过千言万语：

我怎样才能获得该复选框和组合框到表？

我正在使用NetBeans。我尝试使用拖放，但没有奏效。

这是我的表单代码。

public class HttpOutput extends javax.swing.JPanel { 
    HttpElements current_Http_EleObject; 
    /** 
    * Creates new form HttpOutput 
    */ 
    public HttpOutput(HttpElements httpelements) { 
     initComponents(); 
     current_Http_EleObject=httpelements; 
     TableColumn includeColumn = jTable1.getColumnModel().getColumn(0); 
      includeColumn.setCellEditor(new DefaultCellEditor(new JCheckBox())); 
    }

Answer 2

includeColumn.setCellEditor(new DefaultCellEditor(new JCheckBox())); 

• 有没有理由使用或JTable写JCheckBoxRenderer和Editor，放在那里true/false，因为JTable has built_in support for JCheckbox as Renderer and Editor too

• 覆盖适当column，returns Boolean.Class

• 为JComboBox阅读Using a Combo Box as an Editor

• 每一个数据都存储在XxxTableModel，利用DefaultTableModel是在JTables view

• 自动显示事件与XxxTableModel所有更新必须在Event Dispatch Thread
