java BufferedImage生成表格

可以使用Java的BufferedImage类来生成表格。以下是一个简单的示例代码：

import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics2D;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

import javax.imageio.ImageIO;

public class TableGenerator {
    public static void main(String[] args) {
        int rows = 5;
        int cols = 3;
        int cellWidth = 100;
        int cellHeight = 50;
        int tableWidth = cols * cellWidth;
        int tableHeight = rows * cellHeight;

        BufferedImage tableImage = new BufferedImage(tableWidth, tableHeight, BufferedImage.TYPE_INT_RGB);
        Graphics2D g2d = tableImage.createGraphics();

        g2d.setColor(Color.WHITE);
        g2d.fillRect(0, 0, tableWidth, tableHeight);

        g2d.setColor(Color.BLACK);
        g2d.setFont(new Font("Arial", Font.BOLD, 12));

        for (int i = 0; i < rows; i++) {
            for (int j = 0; j < cols; j++) {
                int x = j * cellWidth;
                int y = i * cellHeight;
                g2d.drawRect(x, y, cellWidth, cellHeight);
                g2d.drawString("Cell " + i + "," + j, x + 5, y + 15);
            }
        }

        g2d.dispose();

        try {
            ImageIO.write(tableImage, "png", new File("table.png"));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

这个示例代码生成了一个5行3列的表格，并将其保存为PNG格式的图片。你可以根据需要修改行数、列数、单元格大小、字体等参数来生成不同的表格。
