当2个学生的时候,每个学生固定是2页,循环生产完是4页,现在只能出来第一个学生的第一页第二个学生的两页,如果是10个学生就是前面9个学生都没第二页,最后一个有第二页,不知道怎么回事,求大神解决下,歇歇啦!感激不尽

第一个成绩单你打印的第二页的时候是有空行的。刚好第二个成绩单的第一页可以放得下，就会覆盖掉。你可以在第二个循环的后面加
document.add(new Paragraph("\n")); 试试，多跳几行空行。
cell = new PdfPCell(new Paragraph("此表装入学生档案", title1));
cell.setBorder(0);
cell.setColspan(3);
cell.setHorizontalAlignment(Element.ALIGN_LEFT);
table0.addCell(cell);
cell = new PdfPCell(new Paragraph("北京市教育委员会监制", title1));
cell.setBorder(0);
cell.setColspan(1);
cell.setHorizontalAlignment(Element.ALIGN_RIGHT);
table0.addCell(cell);
document.add(table0);
document.add(new Paragraph("\n"));
document.add(new Paragraph("\n"));
document.add(new Paragraph("\n"));
System.out.println(ys);
就像这样
解决了,谢谢各位帮助解答,把open放到循环外面就可以了
