我有这段代码。我想添加一些命令，以便从 drawgrid 与“konichiwa”一起出现在 JPanel 事情我试过使用谷歌上的一些命令，比如。 JTable table = new JTable(rec, header); . 我还没有找到其他方法将表实现到面板中，所以如果有人能建议一个可能有效的命令。

import java.util.Random;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.TableModel;
@SuppressWarnings({"serial", "unused"})
public class OnO extends JPanel {
    public static void main(String[] argv) throws Exception {
        int i = yesno("Play game? D:");
        if (i == JOptionPane.YES_OPTION) {
            JFrame f = new JFrame("WELCOME!"); // initializes objects from class JFrame
            JLabel label1 = new JLabel("konichiwa"); // initializes objects from class JLabel
            f.add(label1); // f calls the add function
            f.pack(); // f calls the pack function
            JTable table = new JTable(d);
            f.add(new JScrollPane(table));
            f.add(table);
            f.setSize(550, 400);
            f.setVisible(true); // f calls the set visible function
            // when program gets big, need a way to route
        } else {
            System.exit(0);
        }
    }
    public static int yesno(String theMessage) {
        int result = JOptionPane.showConfirmDialog(null, theMessage,
                "WELCOME", JOptionPane.YES_NO_OPTION);
        return result;
    }
    public static String drawgrid() {
        String s = null;
        int[][] board = new int[16][16];
        int i;
        int j;
        Random r = new Random();
        int low = 0;
        int high = 2;
        for (i = 0; i < 16; i++) {
            for (j = 0; j < 16; j++) {
                int result = r.nextInt(high - low) + low;
                board[i][j] = result;
            }
        }
        for (int[] row : board) {
            printRow(row);
        }
        return s;
    }
    public static void printRow(int[] row) {
        for (int i : row) {
            System.out.print(i);
            System.out.print("\t");
        }
        System.out.println();
    }
