帮我写一个绘制表格图片，能控制每列的单元格宽度且成向单元格填入数据的java代码

好的，以下是一个简单的Java代码示例，可以绘制表格图片并控制每列的单元格宽度，在单元格中填入数据：

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 TableImageGenerator {
    private int width;
    private int height;
    private int numCols;
    private int numRows;
    private int[] colWidths;
    private String[][] data;
    private BufferedImage image;
    private Graphics2D g2d;
    private Font font = new Font("Arial", Font.PLAIN, 12);
    private Color bgColor = Color.WHITE;
    private Color fgColor = Color.BLACK;

    public TableImageGenerator(int width, int height, int numCols, int numRows, int[] colWidths, String[][] data) {
        this.width = width;
        this.height = height;
        this.numCols = numCols;
        this.numRows = numRows;
        this.colWidths = colWidths;
        this.data = data;

        // create a new image buffer
        image = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
        g2d = image.createGraphics();

        // set background color
        g2d.setColor(bgColor);
        g2d.fillRect(0, 0, width, height);

        // set font
        g2d.setFont(font);

        // set foreground color
        g2d.setColor(fgColor);
    }

    public void drawTable() {
        int x = 0;
        int y = 0;

        // draw table header
        for (int i = 0; i < numCols; i++) {
            g2d.drawString(data[0][i], x, y + font.getSize());
            x += colWidths[i];
        }

        // draw horizontal line
        y += 2 * font.getSize();
        g2d.drawLine(0, y, width, y);

        // draw table data
        for (int i = 1; i < numRows; i++) {
            x = 0;
            y += font.getSize();
            for (int j = 0; j < numCols; j++) {
                g2d.drawString(data[i][j], x, y + font.getSize());
                x += colWidths[j];
            }
        }
    }

    public void saveImage(String filename) throws IOException {
        ImageIO.write(image, "png", new File(filename));
    }

    public static void main(String[] args) throws IOException {
        int width = 400;
        int height = 300;
        int numCols = 3;
        int numRows = 4;
        int[] colWidths = {100, 150, 150};
        String[][] data = {
            {"Name", "Age", "Gender"},
            {"John", "25", "Male"},
            {"Mary", "30", "Female"},
            {"Bob", "35", "Male"}
        };

        TableImageGenerator generator = new TableImageGenerator(width, height, numCols, numRows, colWidths, data);
        generator.drawTable();
        generator.saveImage("table.png");
    }
}

这段代码会生成一个包含表格数据的PNG格式图片文件。你可以根据自己的需求修改代码中的参数来生成不同的表格图片。
