一、引入相关jar
<dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>3.10-FINAL</version></dependency>
二、原始写法
1）、在首页插入一个表格，单元格中带有图片
public static void writeTblWithImageToDocx_1() {BufferedReader in = null;XWPFDocument temp = null;BufferedOutputStream out = null;File tempDoc = new File("d:\\test\\test11.docx");try {//in = new BufferedReader(new InputStreamReader(new FileInputStream("D:\\test\\2.doc"), "ISO8859_1"));temp = new XWPFDocument(new BufferedInputStream(new FileInputStream(tempDoc)));out = new BufferedOutputStream(new FileOutputStream("D:\\test\\test_2.docx"));XWPFParagraph p = temp.getParagraphArray(0);p.setAlignment(ParagraphAlignment.LEFT);XWPFRun run = p.insertNewRun(0);//表格生成 6行5列.int rows = 6;int cols = 5;XmlCursor cursor = p.getCTP().newCursor();XWPFTable tableOne = temp.insertNewTbl(cursor);//样式控制CTTbl ttbl = tableOne.getCTTbl();CTTblPr tblPr = ttbl.getTblPr() == null ? ttbl.addNewTblPr() : ttbl.getTblPr();CTTblWidth tblWidth = tblPr.isSetTblW() ? tblPr.getTblW() : tblPr.addNewTblW();CTJc cTJc = tblPr.addNewJc();cTJc.setVal(STJc.Enum.forString("center"));//表格居中tblWidth.setW(new BigInteger("9000"));//每个表格宽度tblWidth.setType(STTblWidth.AUTO);//表格创建XWPFTableRow tableRowTitle = tableOne.getRow(0);tableRowTitle.getCell(0).setText("标题");tableRowTitle.addNewTableCell().setText("内容");tableRowTitle.addNewTableCell().setText("姓名");tableRowTitle.addNewTableCell().setText("日期");tableRowTitle.addNewTableCell().setText("备注");for (int i = 1; i < rows; i++) {XWPFTableRow createRow = tableOne.createRow();for (int j = 0; j < cols; j++) {createRow.getCell(j).setText("我是第"+i+"行,第"+(j+1)+"列");}}//插入图片测试XWPFTableRow rowTest = tableOne.getRow(0);XWPFTableCell imageCell = rowTest.getCell(0);List<XWPFParagraph> paragraphs = imageCell.getParagraphs();XWPFParagraph newPara = paragraphs.get(0);XWPFRun imageCellRunn = newPara.createRun();imageCellRunn.addPicture(new FileInputStream("d:/test/1.png"), XWPFDocument.PICTURE_TYPE_PNG, "1.png", Units.toEMU(600), Units.toEMU(300));run.addBreak();temp.write(out);} catch (UnsupportedEncodingException e) {// TODO 自动生成的 catch 块e.printStackTrace();} catch (FileNotFoundException e) {// TODO 自动生成的 catch 块e.printStackTrace();} catch (IOException e) {// TODO 自动生成的 catch 块e.printStackTrace();} catch (InvalidFormatException i) {// TODO 自动生成的 catch 块i.printStackTrace();}finally {if (in != null) {try {in.close();} catch (IOException e) {// TODO 自动生成的 catch 块e.printStackTrace();}}if (out != null) {try {out.close();} catch (IOException e) {// TODO 自动生成的 catch 块e.printStackTrace();}}// tempDoc.deleteOnExit();}System.out.println("写入完成。。。。。。。。。。。。。。");}
2）、调用该方法
public static void main(String[] args) {writeTblWithImageToDocx_1();}
3）、结果
WPS：图片是空白的图，无法打开，表格宽度样式无效
Office:无法打开
三、修改代码支持可显示图片
Poi代码bug,亲测3.9和3.10都有该问题，其他版本未测，可自行测试。
修改后代码：
1）、首先重写XWPFDocument，定义构造函数，自定义读取图片的方法
public class CustomXWPFDocument extends XWPFDocument {public CustomXWPFDocument(InputStream inputStream) throws IOException {super(inputStream);}public void createPic(String blipId, int id, int width, int height, CTInline inline) {final int EMU = 9525;width *= EMU;height *= EMU;//String blipId = getAllPictures().get(id).getPackageRelationship().getId();//CTInline inline = createParagraph().createRun().getCTR().addNewDrawing().addNewInline();String picXml = "" +"<a:graphic xmlns:a=\"/drawingml//main\">" +" <a:graphicData uri=\"/drawingml//picture\">" +"<pic:pic xmlns:pic=\"/drawingml//picture\">" +" <pic:nvPicPr>" +" <pic:cNvPr id=\"" + id + "\" name=\"Generated\"/>" +" <pic:cNvPicPr/>" +" </pic:nvPicPr>" +" <pic:blipFill>" +" <a:blip r:embed=\"" + blipId + "\" xmlns:r=\"/officeDocument//relationships\"/>" +" <a:stretch>" +" <a:fillRect/>" +" </a:stretch>" +" </pic:blipFill>" +" <pic:spPr>" +" <a:xfrm>" +" <a:off x=\"0\" y=\"0\"/>" +" <a:ext cx=\"" + width + "\" cy=\"" + height + "\"/>" +" </a:xfrm>" +" <a:prstGeom prst=\"rect\">" +" <a:avLst/>" +" </a:prstGeom>" +" </pic:spPr>" +"</pic:pic>" +" </a:graphicData>" +"</a:graphic>";//CTGraphicalObjectData graphicData = inline.addNewGraphic().addNewGraphicData();XmlToken xmlToken = null;try {xmlToken = XmlToken.Factory.parse(picXml);} catch (XmlException xe) {xe.printStackTrace();}inline.set(xmlToken);//graphicData.set(xmlToken);inline.setDistT(0);inline.setDistB(0);inline.setDistL(0);inline.setDistR(0);CTPositiveSize2D extent = inline.addNewExtent();extent.setCx(width);extent.setCy(height);CTNonVisualDrawingProps docPr = inline.addNewDocPr();docPr.setId(id);docPr.setName("Picture " + id);docPr.setDescr("Generated");}}
2）、修改首页插入一个表格，单元格中带有图片的相关代码
public static void writeTblWithImageToDocx_2() {BufferedReader in = null;CustomXWPFDocument temp = null;BufferedOutputStream out = null;File tempDoc = new File("d:\\test\\test11.docx");try {//in = new BufferedReader(new InputStreamReader(new FileInputStream("D:\\test\\2.doc"), "ISO8859_1"));temp = new CustomXWPFDocument(new BufferedInputStream(new FileInputStream(tempDoc)));out = new BufferedOutputStream(new FileOutputStream("D:\\test\\test_2.docx"));XWPFParagraph p = temp.getParagraphArray(0);p.setAlignment(ParagraphAlignment.LEFT);XWPFRun run = p.insertNewRun(0);//表格生成 6行5列.int rows = 6;int cols = 5;XmlCursor cursor = p.getCTP().newCursor();XWPFTable tableOne = temp.insertNewTbl(cursor);//样式控制CTTbl ttbl = tableOne.getCTTbl();CTTblPr tblPr = ttbl.getTblPr() == null ? ttbl.addNewTblPr() : ttbl.getTblPr();CTTblWidth tblWidth = tblPr.isSetTblW() ? tblPr.getTblW() : tblPr.addNewTblW();CTJc cTJc = tblPr.addNewJc();cTJc.setVal(STJc.Enum.forString("center"));//表格居中tblWidth.setW(new BigInteger("8000"));//每个表格宽度tblWidth.setType(STTblWidth.DXA);//表格创建XWPFTableRow tableRowTitle = tableOne.getRow(0);tableRowTitle.setHeight(380);tableRowTitle.getCell(0).setText("标题");tableRowTitle.addNewTableCell().setText("内容");tableRowTitle.addNewTableCell().setText("姓名");tableRowTitle.addNewTableCell().setText("日期");tableRowTitle.addNewTableCell().setText("备注");for (int i = 1; i < rows; i++) {XWPFTableRow createRow = tableOne.createRow();for (int j = 0; j < cols; j++) {createRow.getCell(j).setText("我是第"+i+"行,第"+(j+1)+"列");}}//插入图片测试XWPFTableRow rowTest = tableOne.getRow(0);XWPFTableCell imageCell = rowTest.getCell(0);List<XWPFParagraph> paragraphs = imageCell.getParagraphs();XWPFParagraph newPara = paragraphs.get(0);XWPFRun imageCellRunn = newPara.createRun();String id = temp.addPictureData(new FileInputStream("d:/test/1.png"), XWPFDocument.PICTURE_TYPE_PNG);//添加图片数据int id2=temp.getAllPackagePictures().size()+1;CTInline ctinline=imageCellRunn.getCTR().addNewDrawing().addNewInline();//设置段落行temp.createPic(id,id2, 259, 259,ctinline);//添加图片mergeCellsHorizontal(tableOne,0,0,1);//WPS不支持跨列mergeCellsVertically(tableOne,1,1,2);run.addBreak();temp.write(out);} catch (UnsupportedEncodingException e) {// TODO 自动生成的 catch 块e.printStackTrace();} catch (FileNotFoundException e) {// TODO 自动生成的 catch 块e.printStackTrace();} catch (IOException e) {// TODO 自动生成的 catch 块e.printStackTrace();} catch (InvalidFormatException i) {// TODO 自动生成的 catch 块i.printStackTrace();}finally {if (in != null) {try {in.close();} catch (IOException e) {// TODO 自动生成的 catch 块e.printStackTrace();}}if (out != null) {try {out.close();} catch (IOException e) {// TODO 自动生成的 catch 块e.printStackTrace();}}// tempDoc.deleteOnExit();}System.out.println("写入完成。。。。。。。。。。。。。。");}
3）、新增合并单元格相关代码
// word跨列合并单元格public static void mergeCellsHorizontal(XWPFTable table, int row, int fromCell, int toCell) {for (int cellIndex = fromCell; cellIndex <= toCell; cellIndex++) {XWPFTableCell cell = table.getRow(row).getCell(cellIndex);if ( cellIndex == fromCell ) {// The first merged cell is set with RESTART merge valuecell.getCTTc().addNewTcPr().addNewHMerge().setVal(STMerge.RESTART);} else {// Cells which join (merge) the first one, are set with CONTINUEcell.getCTTc().addNewTcPr().addNewHMerge().setVal(STMerge.CONTINUE);}}}// word跨行并单元格public static void mergeCellsVertically(XWPFTable table, int col, int fromRow, int toRow) {for (int rowIndex = fromRow; rowIndex <= toRow; rowIndex++) {XWPFTableCell cell = table.getRow(rowIndex).getCell(col);if ( rowIndex == fromRow ) {// The first merged cell is set with RESTART merge valuecell.getCTTc().addNewTcPr().addNewVMerge().setVal(STMerge.RESTART);} else {// Cells which join (merge) the first one, are set with CONTINUEcell.getCTTc().addNewTcPr().addNewVMerge().setVal(STMerge.CONTINUE);}}}
3）、测试结果
WPS：图片已经正常显示，样式依旧无效，合并列也无效，合并行有效
Office:可以正常显示
