Question

任何人都可以帮我解决这个问题。我有一个String数组，我想在不使用jtable的情况下在表中绘图：

String inventory[][] = {{"Chairs","Tables"},{"Bed","Sofas"}}

我使用嵌套的for循环和drawLine来生成此网格，但我无法将String放在表格中。任何人都可以帮助我吗？

它不是我的程序，但这是关闭的例子，我有互联网形式。我的程序有点类似于此。

import java.awt.* ;
import java.awt.event.* ;
import javax.swing.* ;
import javax.swing.border.TitledBorder;
import javax.swing.border.EtchedBorder;
import java.awt.*;
import java.awt.event.*;

public class testtable extends JFrame {

   private static final int DRAWING_SIZE = 600;
   private static final int SUBDIVISIONS = 2;
   private static final int SUBDIVISION_SIZE = DRAWING_SIZE / SUBDIVISIONS;

   public testtable() {
      setSize(800, 800);
      setLayout(new GridBagLayout());
      GridBagConstraints gbc = new GridBagConstraints();
      gbc.weightx = 1.0;
      gbc.weighty = 1.0;
      gbc.gridx = 0;
      gbc.gridy = 0;
      JLabel drawingBoard = new JLabel("Drawing Board");
      gbc.anchor = GridBagConstraints.SOUTH;
      drawingBoard.setFont(new Font("Serif", Font.BOLD, 28));
      add(drawingBoard, gbc);
      JPanel panel = new JPanel() {
         @Override public void paintComponent(Graphics g) {
            super.paintComponent(g);
            Graphics2D g2 = (Graphics2D) g;
            g2.setPaint(Color.GRAY);
            for (int i = 1; i < SUBDIVISIONS; i++) {
               int x = i * SUBDIVISION_SIZE;
               g2.drawLine(x, 0, x, getSize().height);
            }
            for (int i = 1; i < SUBDIVISIONS; i++) {
               int y = i * SUBDIVISION_SIZE;
               g2.drawLine(0, y, getSize().width, y);
            }
         }
      };
      panel.setPreferredSize(new Dimension(DRAWING_SIZE, DRAWING_SIZE));
      panel.setBackground(Color.WHITE);
      panel.setBorder(BorderFactory.createLineBorder(Color.BLACK));
      gbc.gridy++;
      gbc.anchor = GridBagConstraints.CENTER;
      add(panel, gbc);
      JButton saveDrawing = new JButton("SAVE DRAWING");
      gbc.gridy++;
      gbc.anchor = GridBagConstraints.NORTH;
      add(saveDrawing, gbc);
   }
   public static void main(String[] args) {
      (new testtable()).setVisible(true);
   }
}

有点不清楚，但我想你已经覆盖了某些现有UI类的paint或paintComponent，并使用Graphics.drawLine方法绘制表格。

如果这是正确的，那么你可以制作类似的嵌套循环并在里面调用Graphics.drawString来渲染字符串。考虑字符串是按基线锚定的，而不是左上角的。

UPD。在编辑之前发布，所以答案的第一部分现在看起来很奇怪。
