public class WriterPDF2 {

public static void main(String[] args){
//實例化對象
Document document = new Document(PageSize.A4);
//建立讀寫器

try {
//實列化不同的類,可以生成不同的文件
PdfWriter.getInstance(document, new FileOutputStream("c:\\one.pdf"));//生成PDF

cell = new Cell("aaaaaaaaaaaaaaaaa");
cell.setRowspan(2);
cell.setBorderColor(new Color(255,0,0));

table.addCell(cell);

table.addCell("1.1");
table.addCell("2.1");
table.addCell("1.2");
table.addCell("2.2");

table.addCell("cell test1");
