我正在尝试将页眉和页脚添加到pdf中。我能够以pdf格式获取内容，但问题是内容的对齐方式。任何人都可以验证我的以下代码。页脚的内容与图像重叠。

public class TestPdf {
public static final String DEST = "D://html_header_footer.pdf";

public static final String HEADER = "<table cellspacing=\"0\" cellpadding=\"0\" style=\"width:100%;border:1px solid red;margin:10px;\"><tr><td><img  src=\"C:\\Users\\459495\\Desktop\\header.png\" alt=\"AMHI\"/></td></tr></table>";



public static final String FOOTER = "<html><table  cellspacing=\"0\" cellpadding=\"0\" style=\"width:100%;border:1px solid red;\">\r\n" + 
        "<tr><td colspan=\"2\" style=\"padding:0px 0px 0px 35px;background:green;\"><br/>This is a computer generated letter and does not require signature.</td></tr><tr style =\"width:20%;border:1px solid red;background:black;\"><td style =\"width:20%;border:1px solid red;\"><br/><img width=\"261\" height=\"82\"src=\"C://Users/459495/Desktop/footer.png\" alt=\"AMHI\"/></td><td valign=\"top\" style=\"width:80%;font-family:Helvetica;font-size:9px;padding:10px;border:1px solid red;\"><br/><b>Apollo Munich Health Insurance Co.
