1、实现结果（没有颜色需求）
2、引入jar包：textpdf-5.513.1.jar
3、纯手打，如果复制可能会报错，建议参考。
关键点：1、主要涉及的类 PdfpTable 和 PdfpCell两个了类 ，一个是表格，一个是表格单元
2、document记得open()和close（）
3、属性设置，一般就是字体，是否居中，是否有边框等，如果所示
//设置整个表格的列数
PdfPTable table=new PdfPTable(24);
table.setWidthPercentage(100f);//表格的占比
//开始规划表格
PdfPCell PdfPCell1 =new PdfPCell(new Phrase("党（总）支部"，textfont));
PdfPCell1.setColspan(6);//合并6列
PdfPCell1.setPaddingTop(10);//内上边距
PdfPCell1.setPaddingBottom(10);//内下边距
PdfPCell1.setVerticalAlignment(Cell.ALIGN_MIDDLE);//居中
PdfPCell1.setHorizontalAlignment(Cell.ALIGN_CENTER);//居中
table.addCell(leftTitleOne);
