java写表格生成图片源代码

最近写彩信接口，需要根据配置信息自动生成图片，jfreechar可以搞定柱图，线图，饼图，柱线合图，堆栈图等等所有的，维度表格无法实现。曾经常识通过html2image实现，但是样式无法接受，没办法只能自己写，java代码。源代码如下，仅供参考

public class TestTable {
BufferedImage image;
void createImage(String fileLocation) {
try {
FileOutputStream fos = new FileOutputStream(fileLocation);
BufferedOutputStream bos = new BufferedOutputStream(fos);
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(bos);
encoder.encode(image);
bos.close();
} catch (Exception e) {
e.printStackTrace();
}
}
