### 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

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3htMzkzMzkyNjI1_size_16_color_FFFFFF_t_70 1][]

###  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=\"http://schemas.openxmlformats.org/drawingml/2006/main\">" +
                    "   <a:graphicData uri=\"http://schemas.openxmlformats.org/drawingml/2006/picture\">" +
                    "      <pic:pic xmlns:pic=\"http://schemas.openxmlformats.org/drawingml/2006/picture\">" +
                    " <pic:nvPicPr>" +
                    "    <pic:cNvPr id=\"" + id + "\" name=\"Generated\"/>" +
                    "    <pic:cNvPicPr/>" +
                    " </pic:nvPicPr>" +
                    " <pic:blipFill>" +
                    "    <a:blip r:embed=\"" + blipId + "\" xmlns:r=\"http://schemas.openxmlformats.org/officeDocument/2006/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 value
                    cell.getCTTc().addNewTcPr().addNewHMerge().setVal(STMerge.RESTART);
                } else {
                    // Cells which join (merge) the first one, are set with CONTINUE
                    cell.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 value
                    cell.getCTTc().addNewTcPr().addNewVMerge().setVal(STMerge.RESTART);
                } else {
                    // Cells which join (merge) the first one, are set with CONTINUE
                    cell.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
