如何在Jtable上正确对齐Title边框
我试图在java swing中构建小应用程序。我开始使用此链接：Creating a Grid in Java。
一切都很好。我完成了那个任务，但是我正试图删除多余的标题边框。我试图减少标题边框的边界仍然不影响。任何有良好建议的人都试着与我分享。

我找到了你的问题， 您将scrollPane添加到panel2为
panel2.add(scrollPane1, BorderLayout.CENTER);
但你没有将setLayout设置为panel2的BorderLayout。 并将panel1的布局设置为null 看到这段代码
JPanel panel1 = new JPanel();
panel1.setLayout(null);//add to your code
JPanel panel2 = new JPanel();
panel2.setLayout(new BorderLayout());//add to your code
panel2.setBounds(0,0,800,120);//add to your code
