特定位置插入表格、段落、圖片

• 思路
  在word中做個標記，通常這個標記獨自佔據一個段落，例如

  

  標記示例

  
  我們想要在標記處插入一個表格，一個段落，一幅圖片，其中插入段落可以使用上話提到的文字替換方式，也可以用今天提到的方法。
  具體方法是，獲取這個段落，然後得到一個newXMLCursor，然後用這個遊標插入表格、段落、圖片。程式碼如下
• 插入段落

public static void main(String[] args) throws IOException, InvalidFormatException {
    String filepath = "D:\\users\\IDEA\\POIUtils\\doc\\測試文件.docx";
    String destpath = "D:\\users\\IDEA\\POIUtils\\doc\\測試文件_result.docx";

    OPCPackage opcPackage = POIXMLDocument.openPackage(filepath);
    XWPFDocument xwpfDocument = new XWPFDocument(opcPackage);
    List<XWPFParagraph> xwpfParas = xwpfDocument.getParagraphs();
    int num=0;
    for(int i=0;i<xwpfParas.size();i++){
        if(num==3) break;
        XWPFParagraph xwpfParagraph = xwpfParas.get(i);
        String text=xwpfParagraph.getText();

        //插入段落
        if(text.equals("${mark_newParagraph}")){
            XmlCursor cursor = xwpfParagraph .getCTP().newCursor();
            XWPFParagraph newPara = xwpfDocument.insertNewParagraph(cursor);
            newPara.setAlignment(ParagraphAlignment.BOTH);//兩端對齊
            newPara.setIndentationFirstLine(480);//首行縮排24磅
            XWPFRun newParaRun = newPara.createRun();
            newParaRun.setText("這是新插入的段落！");
            newParaRun.setFontFamily("宋體");
            newParaRun.setFontSize(12);
            newParaRun.setBold(false);
            xwpfDocument.removeBodyElement(xwpfDocument.getPosOfParagraph(xwpfParagraph));
        }

        //插入表格
        if(text.equals("${mark_newTable}")){
            XmlCursor cursor= xwpfParagraph.getCTP().newCursor();
            XWPFTable table = xwpfDocument.insertNewTbl(cursor);

            XWPFTableRow row_0 = table.getRow(0);
            row_0.getCell(0).setText("姓名");
            row_0.addNewTableCell().setText("年齡");

            XWPFTableRow row_1 = table.createRow();
            row_1.getCell(0).setText("隔壁老王");
            row_1.getCell(1).setText("48");

            setTableLocation(table,"center");
            setCellLocation(table,"CENTER","center");
            xwpfDocument.removeBodyElement(xwpfDocument.getPosOfParagraph(xwpfParagraph));
        }

        //插入圖片
        if(text.equals("${mark_newPicture}")){

            XmlCursor cursor = xwpfParagraph .getCTP().newCursor();
            XWPFParagraph newPara = xwpfDocument.insertNewParagraph(cursor);
            newPara.setAlignment(ParagraphAlignment.CENTER);//居中
            XWPFRun newParaRun = newPara.createRun();
            newParaRun.addPicture(new FileInputStream("./doc/bus.png"),XWPFDocument.PICTURE_TYPE_PNG,"bus.png,",Units.toEMU(200), Units.toEMU(200));
            xwpfDocument.removeBodyElement(xwpfDocument.getPosOfParagraph(xwpfParagraph));
        }
    }

    write(xwpfDocument,destpath);
}

    public static void setCellLocation(XWPFTable xwpfTable, String verticalLoction, String horizontalLocation) {

        }
    }

    }
