POI在Word文档插入表格，表格中插入图片总结

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=\"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

Office:可以正常显示
