渲染时的JTable撕裂

夏侯旻
2023-03-14

我已经建立了一个JTable，并使其包含18列。最初，当它是13列时，它非常适合JTable，并且没有撕裂。然而，一旦我使它包含18个表，并将自动调整大小设置为关闭，当我使用水平滚动条尝试滚动其他列时，JTable的撕裂开始发生，如图所示：

Netbeans还开始向我发送大量错误消息，如：

为什么会这样？这个问题有什么解决办法吗？谢谢

真抱歉！下面是用于初始化表的代码。希望会有用！

jp.setLayout(new BorderLayout());
    JTable jt = new JTable(data, column);// data and columns are just 2D and 1D String arrays each
    JTableHeader th = jt.getTableHeader();
    th.setBackground(java.awt.Color.pink);
    th.setEnabled(true);
    jt.setTableHeader(th);
    jt.setEnabled(false);
    jp.add(jt, BorderLayout.CENTER);
    JScrollPane scrollPane = new JScrollPane(jt, JScrollPane.VERTICAL_SCROLLBAR_ALWAYS, JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);
    jt.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
    scrollPane.setEnabled(false);
    jp.add(scrollPane, BorderLayout.CENTER);

答案是这样的：

java线程“AWT-EventQueue-0”中出现异常。lang.ArrayIndexOutofBounds异常：14 at

这意味着它知道它应该有更多的列，并且它想绘制下一列，但无法绘制，因为基础表模型没有那么多列。

为表指定18列意味着您还需要更新关联的表模型。两者都需要同步才能使表正常工作。

我认为您已经声明了比数据数组中更多的列。

此代码示例准确地再现了您的问题：

import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.SwingUtilities;

public class TestTable {

    public JFrame f;
    private JTable table;

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
                new TestTable().initUI();
            }
        });
    }

    protected void initUI() {
        String[][] data = new String[1][1];
        data[0] = new String[] { "hello" };
        String[] columns = new String[] { "Column-1", "Column-2" };
        table = new JTable(data, columns);
        f = new JFrame();
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.setSize(300, 300);
        f.setLocationRelativeTo(null);
        f.add(new JScrollPane(table));
        f.setVisible(true);
    }

}

当然，解决方案是使数据中的列数与声明的列数匹配。您应该确保数据数组的每一行都使用正确数量的“列”进行了初始化。

例如，您可以有：

String[][] data = new String[1][18];
data[0] = new String[15]; // <-- This will cause some problems

现在，我建议使用另一种数据结构而不是数组，因为它不是非常灵活，而且它们往往很难维护。一个简单的解决方案是使用一些“模型”类并创建自己的TableModel，如下所示：

import java.util.List;
import java.util.Random;
import java.util.Vector;

import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.SwingUtilities;
import javax.swing.table.AbstractTableModel;

public class TestTable {

    public JFrame f;
    private JTable table;

    public class ModelObject {
        private String column0; // Consider using something more explicit than column0,1,...
        private String column1;

        public String getColumn0() {
            return column0;
        }

        public void setColumn0(String column0) {
            this.column0 = column0;
        }

        public String getColumn1() {
            return column1;
        }

        public void setColumn1(String column1) {
            this.column1 = column1;
        }

  • 渲染比之前渲染时更多的钩子

    我有一个带有对象数组的组件，其中我正在根据字符串进行过滤。问题是当我尝试将此过滤器的返回设置为本地状态时，它会抛出错误，我不太理解原因。 所以，因为我希望这个数组处于我的状态，所以我决定这样做： 插入这一行后发生的事情是这样的： 它开始多次渲染。我假设，每次状态改变时，它都会重新渲染组件（如果我错了，请纠正我）。不过，我不知道它为什么要多次这样做。 因此，我想过使用 useEffect 来实现此处
