PDF分頁(yè)

操作docment對(duì)象

doc.newPage();

PDF合并單元格

cell = new PdfPCell();//合并這個(gè)cell的第一行開(kāi)始的兩列 setRowspan是合并行，setColspan是合并列cell.setRowspan(1);cell.setColspan(2);table.addCell(cell);

單元格文字水平居中、垂直居中

cell.setVerticalAlignment(Element.ALIGN_MIDDLE); //垂直居中 cell.setHorizontalAlignment(Element.ALIGN_CENTER); //水平居中

設(shè)置單元格高度

cell.setFixedHeight(40f);
