因为工作中要用到，导出不同的PDF，所以学习了Itext

我两天创建的PDF如下所示，主要是简单的表格类的

1、引包

<dependency><groupId>com.itextpdf</groupId><artifactId>itextpdf</artifactId><version>5.5.11</version></dependency><dependency><groupId>com.itextpdf.tool</groupId><artifactId>xmlworker</artifactId><version>5.5.11</version></dependency><!-- 支持中文 --><dependency><groupId>com.itextpdf</groupId><artifactId>itext-asian</artifactId><version>5.2.0</version></dependency><!-- 支持css样式渲染 --><dependency><groupId>org.xhtmlrenderer</groupId><artifactId>flying-saucer-pdf-itext5</artifactId><version>9.1.16</version></dependency><!-- 转换html为标准xhtml包 --><dependency><groupId>net.sf.jtidy</groupId><artifactId>jtidy</artifactId><version>r938</version></dependency>

2、工具类

3、创建一个简单的PDF

public class CreatePDFMainTest {public static void main(String[] args) throws Exception {Document document = new Document(PageSize.A4);//第二步，创建Writer实例PdfWriter.getInstance(document, new FileOutputStream("hello.pdf"));//创建中文字体BaseFont bfchinese = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED);Font fontChinese = new Font(bfchinese, 12, Font.NORMAL);//第三步，打开文档document.open();//第四步，写入内容Paragraph paragraph = new Paragraph("hello world", fontChinese);document.add(paragraph);//第五步，关闭文档document.close();}}

4、我建的表格简单，所以用到API也简单

1、创建一个表格，表格有6列，

并且铺满屏幕

PdfPTable goodTable = new PdfPTable(6);goodTable.setWidthPercentage(100);

2、创建格子

PdfPCell cell;cell = new PdfPCell(new Phrase(“格子内容”, iTextPDFUtil.getColorFont()));//格子横跨2个格子cell.setColspan(2);//格子高度35pxcell.setMinimumHeight(35);//格子纵跨1个格子cell.setRowspan(1);//格子内容左右居中cell.setHorizontalAlignment(Element.ALIGN_CENTER);//格子内容上下居中cell.setVerticalAlignment(Element.ALIGN_MIDDLE);

3、举例如下

package pdfdemo.pdfdemo.utils;import com.itextpdf.text.*;import com.itextpdf.text.pdf.BaseFont;import com.itextpdf.text.pdf.PdfPCell;import com.itextpdf.text.pdf.PdfPTable;import com.itextpdf.text.pdf.PdfWriter;import pdfdemo.pdfdemo.demoOne.iTextPDFUtil;import java.io.FileOutputStream;/*** @program: pdfdemo* @ClassName CreatePDFMainTest* @description:* @author:蒋皓洁* @create: -04-02 11:29* @Version 1.0**/public class CreatePDFMainTest3 {public static void main(String[] args) throws Exception {Document document = new Document(PageSize.A4);//第二步，创建Writer实例PdfWriter.getInstance(document, new FileOutputStream("hello.pdf"));//创建中文字体BaseFont bfchinese = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED);Font fontChinese = new Font(bfchinese, 12, Font.NORMAL);//第三步，打开文档document.open();//第四步，写入内容//创建一列的格子PdfPTable goodTable = new PdfPTable(6);goodTable.setWidthPercentage(100);PdfPCell cell;cell = new PdfPCell(new Phrase("格子内容", iTextPDFUtil.getColorFont()));//格子横跨2个格子cell.setColspan(6);//格子高度35pxcell.setMinimumHeight(35);//格子纵跨1个格子cell.setRowspan(1);//格子内容左右居中cell.setHorizontalAlignment(Element.ALIGN_CENTER);//格子内容上下居中cell.setVerticalAlignment(Element.ALIGN_MIDDLE);goodTable.addCell(cell);PdfPCell cell2 = new PdfPCell(new Phrase("测试左边", iTextPDFUtil.getColorFont()));//格子横跨2个格子cell2.setColspan(3);//格子高度35pxcell2.setMinimumHeight(35);//格子纵跨1个格子cell2.setRowspan(2);//格子内容左右居中cell2.setHorizontalAlignment(Element.ALIGN_CENTER);//格子内容上下居中cell2.setVerticalAlignment(Element.ALIGN_MIDDLE);goodTable.addCell(cell2);PdfPCell cell3= new PdfPCell(new Phrase("测试右上", iTextPDFUtil.getColorFont()));//格子横跨2个格子cell3.setColspan(3);//格子高度35pxcell3.setMinimumHeight(35);//格子纵跨1个格子cell3.setRowspan(1);//格子内容左右居中cell3.setHorizontalAlignment(Element.ALIGN_CENTER);//格子内容上下居中cell3.setVerticalAlignment(Element.ALIGN_MIDDLE);goodTable.addCell(cell3);PdfPCell cell4 = new PdfPCell(new Phrase("测试右下", iTextPDFUtil.getColorFont()));//格子横跨2个格子cell4.setColspan(3);//格子高度35pxcell4.setMinimumHeight(35);//格子纵跨1个格子cell4.setRowspan(1);//格子内容左右居中cell4.setHorizontalAlignment(Element.ALIGN_CENTER);//格子内容上下居中cell4.setVerticalAlignment(Element.ALIGN_MIDDLE);goodTable.addCell(cell4);document.add(goodTable);//第五步，关闭文档document.close();}}

出来的如下

5、表格内嵌（一个table中内嵌宁外一个table）

PdfPTable celltable =new PdfPTable(2);cell =new PdfPCell(celltable);cell.setColspan(2);//横着占用两格cell.setBorderWidth(1);//设置表格的边框宽度为1cell.setPadding(10);//设置表格与上一个表格的填充为10table.addCell(cell);

6、测试demo展示，有些代码可以封装，但是为了方便看且粘贴就没有封装

上面格子的代码展示如下
