我已经搜索了所有内容，但还没有找到可以帮助我的示例...我需要使我的 JTable 的最后一列（由 ms 访问数据库填充）显示为默认未选中的复选框。我从中提取的数据库有数百条记录，但是出于我们的目的，我已将代码和数据库修改为更简单。我想要做的就是让最后一列作为复选框出现在 Java gui 上，用户可以检查并最终保存结果。也许 JTable 不是最好的方法？
对于此代码，我将 Access 数据库命名为 clientEmployee 并添加了四列，最后一列名为“活动”并包含是/否值（访问中的复选框）。
请帮助我，因为我的任务很快就要到期了。谢谢！
This is the main Gui.....

//Elements of Notes Tab

//creates the main tab pane object

//adds tabbed pane to the frame
getContentPane().add(jtp);
//Creats all of the tabs
JPanel jp5 = new JPanel();//checklist tab
//This adds the tabs to the tabbed pane and sets their titles
jtp.addTab("Stakeholders", jp5);
labels5 = new JLabel[2];
buttons5 = new JButton[2];
p1d = new JPanel();
p1d.setLayout(new GridLayout(2,4,5,5));
jp5.setLayout(new FlowLayout());
for(int count=0;count<buttons5.length && count<labels5.length; count++) {
labels5[count] = new JLabel(fldLabel5[count]);
buttons5[count] = new JButton(fldLabel5[count]);
p1d.add(buttons5[count]);
