先看效果图
这里说明一下这个页码是独立的覆盖在头部上的，不是写在头部里面 线条是默认的不需要的话设置
cell.setBorder(0);
需要引用的核心包有

}下面啰嗦点说说关键代码所在的位置（搜索下面提供的关键代码定位代码位置）
1、复用头部 BasePDFWrite 类
table.setHeaderRows(10);这是复用前10行的单元格，让其重新出现在下一页的最上面
2、页脚 BasePDFWrite 类
//页脚
PdfPTable table1 = BasePDFWrite.createTable(new float[] { 10, 25, 10,20 , 17,18});
table1.setTotalWidth(document.right());
table1.addCell(BasePDFWrite.createCell(operator,BasePDFWrite.headFont, Element.ALIGN_RIGHT)); //制单人
table1.addCell(BasePDFWrite.createCell(" ", BasePDFWrite.headFont, Element.ALIGN_CENTER));
table1.addCell(BasePDFWrite.createCell(" ", BasePDFWrite.headFont , Element.ALIGN_CENTER, Element.ALIGN_CENTER, 2, 0));
table1.addCell(BasePDFWrite.createCell(" ", BasePDFWrite.headFont, Element.ALIGN_RIGHT));
table1.addCell(BasePDFWrite.createCell(" ", BasePDFWrite.headFont, Element.ALIGN_LEFT));
//设置所在位置
table1.writeSelectedRows(0, -1, 0,document.bottom() + 35, writer.getDirectContent());每页都新增一个页脚，生成完页面后 在开一个新的页面
document.newPage();3、动态生成 页码
首先得创建PageXofY 类
在BasePDFWrite 类 初始化 document 时设入值 （最好根据提供的关键代码搜索原文位置去看）
writer.setPageEvent(new PageXofY());到这里就相当于在页面上打了一个标记
下面是计算页码的代码 上面效果图是 1/2 这样的 实际是拼凑出来的 两个部分 “1/” 第几页 + "2"总页数 位置的话需要大家慢慢调了
public void onEndPage(PdfWriter writer, Document document) {
PdfContentByte cb = writer.getDirectContent();
cb.saveState();
String text = "" + writer.getPageNumber() + " / ";
float textX = document.right()-130;
float textY =document.top()-55;
cb.beginText();
cb.setFontAndSize(helv, fontSize);
//第几页 位置
cb.setTextMatrix(textX, textY );
cb.showText(text);
cb.endText();
// 总页数 位置
cb.addTemplate(total, textX +20, textY);
cb.restoreState();
}
