java - 渲染时 JTable 撕裂

Question

我设置了一个 JTable 并使其包含 18 列。最初，当它有 13 列时，它很适合 JTable 并且没有撕裂。但是，一旦我让它包含 18 个表，并将 autoresize 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 也开始给我很多这样的错误信息:

Why is this so? Are there any solution to this problem? Thanks!

So sorry! Here are the code used to initialize the table.Hope it will be useful!

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);

Answer 1

我认为您声明的列比数据数组中的列多。

此代码示例完全重现了您的问题:

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);
    }

}

解决方案当然是使数据中的列数与声明的列数相匹配。并且您应该确保数据数组的每个“行”都使用正确数量的“列”进行了初始化。

例如你可以这样:

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，因为它不是很灵活，而且它们往往难以维护。一个简单的解决方案是拥有一些“模型”类并像这样创建您自己的 TableModel:

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;
        }
    }

    private class TableModel extends AbstractTableModel {

        private List<ModelObject> data;

        protected TableModel(List<ModelObject> data) {
            super();
            this.data = data;
        }

        @Override
        public int getRowCount() {
            return data.size();
        }

        @Override
        public String getColumnName(int column) {
            switch (column) {
            case 0:
                return "Header 0";
            case 1:
                return "Header 1";
            }
            System.err.println("Only two columns are known in this table model");
            return "???";
        }

        @Override
        public int getColumnCount() {
            return 2;
        }

        @Override
        public Object getValueAt(int rowIndex, int columnIndex) {
            ModelObject o = data.get(rowIndex);
