java - 将表添加到java swing

Question

我已经有一个面板，我在其中添加了按钮和一个文本区域。现在我需要在它下面显示一个表格。面板的布局是 AbsoluteLayout，如果我使用以下方法膨胀表格，它会显示为空

        String data[][] = { { "vinod", "BCA", "A" }, { "Raju", "MCA", "b" },
                { "Ranjan", "MBA", "c" }, { "Rinku", "BCA", "d" } };

        String col[] = { "Name", "Course", "Grade" };
        JTable table = new JTable(data, col);
        table.setLocation(25,343);
        panel.add(table, BorderLayout.CENTER);

然而，当我使用 setbounds 时，表格显示正常，但它占用的空间比它需要的多，并且线条不显示在空白空间中，看起来很糟糕。有谁知道如何只设置表格的 x,y 位置并保留其余位置(宽度和高度以适应所需的内容)

String data[][] = { { "vinod", "BCA", "A" }, { "Raju", "MCA", "b" },
        { "Ranjan", "MBA", "c" }, { "Rinku", "BCA", "d" } };

String col[] = { "Name", "Course", "Grade" };
JTable table = new JTable(data, col);
table.setBounds(25,343,122,122);
panel.add(table, BorderLayout.CENTER);

Answer 1

• do not use AbsoluteLayout ，导致调整大小等问题

• 放JTable to the JScrollPane , 不要使用 JPanel as container for JTable

• 阅读有关 How to use JTable 的 Oracles 教程,
