POI在Word文档插入表格，表格中插入图片总结

一、引入相关jar

1.  
   <dependency>
2.  
   <groupId>org.apache.poi</groupId>
3.  
   <artifactId>poi-ooxml</artifactId>
4.  
   <version>3.10-FINAL</version>
5.  
   </dependency>

二、原始写法

1）、在首页插入一个表格，单元格中带有图片

1.  
   public static void writeTblWithImageToDocx_1() {
2.  
   BufferedReader in = null;
3.  
   XWPFDocument temp = null;
4.  
   BufferedOutputStream out = null;
5.  
   File tempDoc = new File("d:\\test\\test11.docx");
6.  
   try {
7.  
   //in = new BufferedReader(new InputStreamReader(new FileInputStream("D:\\test\\2.doc"), "ISO8859_1"));
8.  
   temp = new XWPFDocument(new BufferedInputStream(new FileInputStream(tempDoc)));
9.  
   out = new BufferedOutputStream(new FileOutputStream("D:\\test\\test_2.docx"));
10.  
    XWPFParagraph p = temp.getParagraphArray( 0);
11.  
    p.setAlignment(ParagraphAlignment.LEFT);
12.  
    XWPFRun run = p.insertNewRun( 0);
13.  
     
14.  
    //表格生成 6行5列.
15.  
    int rows = 6;
16.  
    int cols = 5;
17.  
    XmlCursor cursor = p.getCTP().newCursor();
18.  
    XWPFTable tableOne = temp.insertNewTbl(cursor);
19.  
     
20.  
    //样式控制
21.  
    CTTbl ttbl = tableOne.getCTTbl();
22.  
    CTTblPr tblPr = ttbl.getTblPr() == null ? ttbl.addNewTblPr() : ttbl.getTblPr();
23.  
    CTTblWidth tblWidth = tblPr.isSetTblW() ? tblPr.getTblW() : tblPr.addNewTblW();
24.  
    CTJc cTJc = tblPr.addNewJc();
25.  
    cTJc.setVal(STJc.Enum.forString( "center"));//表格居中
26.  
    tblWidth.setW( new BigInteger("9000"));//每个表格宽度
27.  
    tblWidth.setType(STTblWidth.AUTO);
28.  
     
29.  
    //表格创建
30.  
    XWPFTableRow tableRowTitle = tableOne.getRow( 0);
31.  
    tableRowTitle.getCell( 0).setText("标题");
32.  
    tableRowTitle.addNewTableCell().setText( "内容");
33.  
    tableRowTitle.addNewTableCell().setText( "姓名");
34.  
    tableRowTitle.addNewTableCell().setText( "日期");
35.  
    tableRowTitle.addNewTableCell().setText( "备注");
36.  
    for (int i = 1; i < rows; i++) {
37.  
    XWPFTableRow createRow = tableOne.createRow();
38.  
    for (int j = 0; j < cols; j++) {
39.  
    createRow.getCell(j).setText( "我是第"+i+"行,第"+(j+1)+"列");
40.  
    }
41.  
    }
42.  
     
43.  
    //插入图片测试
44.  
    XWPFTableRow rowTest = tableOne.getRow( 0);
45.  
     
46.  
    XWPFTableCell imageCell = rowTest.getCell( 0);
47.  
    List<XWPFParagraph> paragraphs = imageCell.getParagraphs();
48.  
    XWPFParagraph newPara = paragraphs.get( 0);
49.  
    XWPFRun imageCellRunn = newPara.createRun();
50.  
    imageCellRunn.addPicture( new FileInputStream("d:/test/1.png"), XWPFDocument.PICTURE_TYPE_PNG, "1.png", Units.toEMU(600), Units.toEMU(300));
51.  
    run.addBreak();
52.  
    temp.write(out);
53.  
    } catch (UnsupportedEncodingException e) {
54.  
    // TODO 自动生成的 catch 块
55.  
    e.printStackTrace();
56.  
    } catch (FileNotFoundException e) {
57.  
    // TODO 自动生成的 catch 块
58.  
    e.printStackTrace();
59.  
    } catch (IOException e) {
60.  
    // TODO 自动生成的 catch 块
61.  
    e.printStackTrace();
62.  
    } catch (InvalidFormatException i) {
63.  
    // TODO 自动生成的 catch 块
64.  
    i.printStackTrace();
65.  
    }
66.  
    finally {
67.  
    if (in != null) {
68.  
    try {
69.  
    in.close();
70.  
    } catch (IOException e) {
71.  
    // TODO 自动生成的 catch 块
72.  
    e.printStackTrace();
73.  
    }
74.  
    }
75.  
    if (out != null) {
76.  
    try {
77.  
    out.close();
78.  
    } catch (IOException e) {
79.  
    // TODO 自动生成的 catch 块
80.  
    e.printStackTrace();
81.  
    }
82.  
    }
83.  
    // tempDoc.deleteOnExit();
84.  
    }
85.  
     
86.  
    System.out.println( "写入完成。。。。。。。。。。。。。。");
87.  
    }

2）、调用该方法

1.  
   public static void main(String[] args) {
2.  
   writeTblWithImageToDocx_1();
3.  
    
4.  
   }

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

1.  
   public class CustomXWPFDocument extends XWPFDocument {
2.  
    
3.  
   public CustomXWPFDocument(InputStream inputStream) throws IOException {
4.  
   super(inputStream);
5.  
   }
6.  
   public void createPic(String blipId, int id, int width, int height, CTInline inline) {
7.  
   final int EMU = 9525;
8.  
   width *= EMU;
9.  
   height *= EMU;
10.  
    //String blipId = getAllPictures().get(id).getPackageRelationship().getId();
11.  
     
12.  
     
13.  
    //CTInline inline = createParagraph().createRun().getCTR().addNewDrawing().addNewInline();
14.  
     
15.  
     
16.  
    String picXml = "" +
17.  
    "<a:graphic xmlns:a=\"http://schemas.openxmlformats.org/drawingml/2006/main\">" +
18.  
    " <a:graphicData uri=\"http://schemas.openxmlformats.org/drawingml/2006/picture\">" +
19.  
    " <pic:pic xmlns:pic=\"http://schemas.openxmlformats.org/drawingml/2006/picture\">" +
20.  
    " <pic:nvPicPr>" +
21.  
    " <pic:cNvPr id=\"" + id + "\" name=\"Generated\"/>" +
22.  
    " <pic:cNvPicPr/>" +
23.  
    " </pic:nvPicPr>" +
24.  
    " <pic:blipFill>" +
25.  
    " <a:blip r:embed=\"" + blipId + "\" xmlns:r=\"http://schemas.openxmlformats.org/officeDocument/2006/relationships\"/>" +
26.  
    " <a:stretch>" +
27.  
    " <a:fillRect/>" +
28.  
    " </a:stretch>" +
29.  
    " </pic:blipFill>" +
30.  
    " <pic:spPr>" +
31.  
    " <a:xfrm>" +
32.  
    " <a:off x=\"0\" y=\"0\"/>" +
33.  
    " <a:ext cx=\"" + width + "\" cy=\"" + height + "\"/>" +
34.  
    " </a:xfrm>" +
35.  
    " <a:prstGeom prst=\"rect\">" +
36.  
    " <a:avLst/>" +
37.  
    " </a:prstGeom>" +
38.  
    " </pic:spPr>" +
39.  
    " </pic:pic>" +
40.  
    " </a:graphicData>" +
41.  
    "</a:graphic>";
42.  
     
43.  
     
44.  
    //CTGraphicalObjectData graphicData = inline.addNewGraphic().addNewGraphicData();
45.  
    XmlToken xmlToken = null;
46.  
    try {
47.  
    xmlToken = XmlToken.Factory.parse(picXml);
48.  
    } catch (XmlException xe) {
49.  
    xe.printStackTrace();
50.  
    }
51.  
    inline.set(xmlToken);
52.  
    //graphicData.set(xmlToken);
53.  
     
54.  
     
55.  
    inline.setDistT( 0);
56.  
    inline.setDistB( 0);
57.  
    inline.setDistL( 0);
58.  
    inline.setDistR( 0);
59.  
     
60.  
     
61.  
    CTPositiveSize2D extent = inline.addNewExtent();
62.  
    extent.setCx(width);
63.  
    extent.setCy(height);
64.  
     
65.  
     
66.  
    CTNonVisualDrawingProps docPr = inline.addNewDocPr();
67.  
    docPr.setId(id);
68.  
    docPr.setName( "Picture " + id);
69.  
    docPr.setDescr( "Generated");
70.  
    }
71.  
     
72.  
     
73.  
    }

2）、修改首页插入一个表格，单元格中带有图片的相关代码

1.  
   public static void writeTblWithImageToDocx_2() {
2.  
   BufferedReader in = null;
3.  
   CustomXWPFDocument temp = null;
4.  
   BufferedOutputStream out = null;
5.  
   File tempDoc = new File("d:\\test\\test11.docx");
6.  
   try {
7.  
   //in = new BufferedReader(new InputStreamReader(new FileInputStream("D:\\test\\2.doc"), "ISO8859_1"));
8.  
   temp = new CustomXWPFDocument(new BufferedInputStream(new FileInputStream(tempDoc)));
9.  
    
10.  
    out = new BufferedOutputStream(new FileOutputStream("D:\\test\\test_2.docx"));
11.  
    XWPFParagraph p = temp.getParagraphArray( 0);
12.  
    p.setAlignment(ParagraphAlignment.LEFT);
13.  
    XWPFRun run = p.insertNewRun( 0);
14.  
     
15.  
    //表格生成 6行5列.
16.  
    int rows = 6;
17.  
    int cols = 5;
18.  
    XmlCursor cursor = p.getCTP().newCursor();
19.  
    XWPFTable tableOne = temp.insertNewTbl(cursor);
20.  
     
21.  
    //样式控制
22.  
    CTTbl ttbl = tableOne.getCTTbl();
23.  
    CTTblPr tblPr = ttbl.getTblPr() == null ? ttbl.addNewTblPr() : ttbl.getTblPr();
24.  
    CTTblWidth tblWidth = tblPr.isSetTblW() ? tblPr.getTblW() : tblPr.addNewTblW();
25.  
    CTJc cTJc = tblPr.addNewJc();
26.  
    cTJc.setVal(STJc.Enum.forString( "center"));//表格居中
27.  
    tblWidth.setW( new BigInteger("8000"));//每个表格宽度
28.  
    tblWidth.setType(STTblWidth.DXA);
29.  
     
30.  
    //表格创建
31.  
    XWPFTableRow tableRowTitle = tableOne.getRow( 0);
32.  
    tableRowTitle.setHeight( 380);
33.  
     
34.  
    tableRowTitle.getCell( 0).setText("标题");
35.  
    tableRowTitle.addNewTableCell().setText( "内容");
36.  
    tableRowTitle.addNewTableCell().setText( "姓名");
37.  
    tableRowTitle.addNewTableCell().setText( "日期");
38.  
    tableRowTitle.addNewTableCell().setText( "备注");
39.  
    for (int i = 1; i < rows; i++) {
40.  
    XWPFTableRow createRow = tableOne.createRow();
41.  
    for (int j = 0; j < cols; j++) {
42.  
    createRow.getCell(j).setText( "我是第"+i+"行,第"+(j+1)+"列");
43.  
    }
44.  
    }
45.  
     
46.  
    //插入图片测试
47.  
    XWPFTableRow rowTest = tableOne.getRow( 0);
48.  
     
49.  
    XWPFTableCell imageCell = rowTest.getCell( 0);
50.  
    List<XWPFParagraph> paragraphs = imageCell.getParagraphs();
51.  
    XWPFParagraph newPara = paragraphs.get( 0);
52.  
    XWPFRun imageCellRunn = newPara.createRun();
53.  
    String id = temp.addPictureData( new FileInputStream("d:/test/1.png"), XWPFDocument.PICTURE_TYPE_PNG);//添加图片数据
54.  
     
55.  
    int id2=temp.getAllPackagePictures().size()+1;
56.  
     
57.  
    CTInline ctinline=imageCellRunn.getCTR().addNewDrawing().addNewInline(); //设置段落行
58.  
    temp.createPic(id,id2, 259, 259,ctinline);//添加图片
59.  
     
60.  
    mergeCellsHorizontal(tableOne, 0,0,1);//WPS不支持跨列
61.  
    mergeCellsVertically(tableOne, 1,1,2);
62.  
    run.addBreak();
63.  
    temp.write(out);
64.  
    } catch (UnsupportedEncodingException e) {
65.  
    // TODO 自动生成的 catch 块
66.  
    e.printStackTrace();
67.  
    } catch (FileNotFoundException e) {
68.  
    // TODO 自动生成的 catch 块
69.  
    e.printStackTrace();
70.  
    } catch (IOException e) {
71.  
    // TODO 自动生成的 catch 块
72.  
    e.printStackTrace();
73.  
    } catch (InvalidFormatException i) {
74.  
    // TODO 自动生成的 catch 块
75.  
    i.printStackTrace();
76.  
    }
77.  
    finally {
78.  
    if (in != null) {
79.  
    try {
80.  
    in.close();
81.  
    } catch (IOException e) {
82.  
    // TODO 自动生成的 catch 块
83.  
    e.printStackTrace();
84.  
    }
85.  
    }
86.  
    if (out != null) {
87.  
    try {
88.  
    out.close();
89.  
    } catch (IOException e) {
90.  
    // TODO 自动生成的 catch 块
91.  
    e.printStackTrace();
92.  
    }
93.  
    }
94.  
    // tempDoc.deleteOnExit();
95.  
    }
96.  
     
97.  
    System.out.println( "写入完成。。。。。。。。。。。。。。");
98.  
    }

3）、新增合并单元格相关代码

1.  
   // word跨列合并单元格
2.  
   public static void mergeCellsHorizontal(XWPFTable table, int row, int fromCell, int toCell) {
3.  
   for (int cellIndex = fromCell; cellIndex <= toCell; cellIndex++) {
4.  
   XWPFTableCell cell = table.getRow(row).getCell(cellIndex);
5.  
   if ( cellIndex == fromCell ) {
6.  
   // The first merged cell is set with RESTART merge value
7.  
   cell.getCTTc().addNewTcPr().addNewHMerge().setVal(STMerge.RESTART);
8.  
   } else {
9.  
   // Cells which join (merge) the first one, are set with CONTINUE
10.  
    cell.getCTTc().addNewTcPr().addNewHMerge().setVal(STMerge.CONTINUE);
11.  
    }
12.  
    }
13.  
    }
14.  
    // word跨行并单元格
15.  
    public static void mergeCellsVertically(XWPFTable table, int col, int fromRow, int toRow) {
16.  
    for (int rowIndex = fromRow; rowIndex <= toRow; rowIndex++) {
17.  
    XWPFTableCell cell = table.getRow(rowIndex).getCell(col);
18.  
    if ( rowIndex == fromRow ) {
19.  
    // The first merged cell is set with RESTART merge value
20.  
    cell.getCTTc().addNewTcPr().addNewVMerge().setVal(STMerge.RESTART);
21.  
    } else {
22.  
    // Cells which join (merge) the first one, are set with CONTINUE
23.  
    cell.getCTTc().addNewTcPr().addNewVMerge().setVal(STMerge.CONTINUE);
24.  
    }
25.  
    }
26.  
    }

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
