Question

我的JTable似乎有困难，因为它没有显示标题; ＆＃34;＆＃34;姓名＆＃34;，＆＃34; ID＆＃34;，＆＃34;国籍＆＃34;，＆＃34;语言＆＃34;，＆＃34;条件＆＃34;，＆＃34; Ward＆＃34;，＆＃34; Food Preference＆＃34;，＆＃34; Blood Type＆＃34;，＆＃34; Allergy＆＃34;。

这是我的代码：

package searchengine;

import java.awt.EventQueue;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.ListSelectionModel;
import javax.swing.border.EmptyBorder;
import javax.swing.table.TableModel;
import javax.swing.table.TableRowSorter;
import javax.swing.JList;
import javax.swing.table.DefaultTableModel;
import java.awt.Color;
import java.awt.Container;
import java.awt.Font;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;

public class SearchResults extends JFrame {

private JPanel contentPane;
private JTable table;
private JTable SearchTable;
private Container frame;

/**

public static void main(String[] args) {
    EventQueue.invokeLater(new Runnable() {
        public void run() {
            try {
                SearchResults frame = new SearchResults();
                frame.setVisible(true);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    });
}

/**
 * Create the frame.
 */
public SearchResults() {
    setTitle("Search Results");
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setBounds(100, 100, 750, 830);
    contentPane = new JPanel();
    contentPane.setBackground(Color.LIGHT_GRAY);
    contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
    setContentPane(contentPane);
    contentPane.setLayout(null);

    SearchTable = new JTable();
    SearchTable.setFont(new Font("Tahoma", Font.PLAIN, 14));
    SearchTable.setBackground(Color.WHITE);
    SearchTable.setModel(new DefaultTableModel(
        new Object[][] {

    SearchTable.setColumnSelectionAllowed(true);
    SearchTable.setBounds(0, 194, 728, 128);
    contentPane.add(SearchTable);

    final JButton btnBack = new JButton("Back to Search");
    btnBack.setBounds(225, 418, 267, 112);
    contentPane.add(btnBack);
    btnBack.addActionListener(new ActionListener() 
    {
        public void actionPerformed(ActionEvent e) {
            this.setVisible(false);
            new Search().setVisible(true); // Main Form to show after the Login Form..
        }

        private void setVisible(boolean b) {
            // TODO Auto-generated method stub

        }
    });


}
}

Answer 1

JTable需要正确显示“JScrollPane”。

只需更换此

即可修复

SearchTable.setBounds(0, 194, 728, 128);
contentPane.add(SearchTable);

使用

JScrollPane sp = new JScrollPane(SearchTable);
sp.setSize(new Dimension(728, 128));
sp.setLocation(0, 194);
contentPane.add(sp);
