特定位置插入表格、段落、图片

- *
思路
在word中做个标记，通常这个标记独自占据一个段落，例如
标记示例
我们想要在标记处插入一个表格，一个段落，一幅图片，其中插入段落可以使用上话提到的文本替换方式，也可以用今天提到的方法。
具体方法是，获取这个段落，然后得到一个newXMLCursor，然后用这个游标插入表格、段落、图片。代码如下
插入段落

public static void main(String[] args) throws IOException, InvalidFormatException {
    String filepath = "D:\\users\\IDEA\\POIUtils\\doc\\测试文档.docx";
    String destpath = "D:\\users\\IDEA\\POIUtils\\doc\\测试文档_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);//两端对齐
            newPara.setIndentationFirstLine(480);//首行缩进24磅
            XWPFRun newParaRun = newPara.createRun();
            newParaRun.setText("这是新插入的段落！");
            newParaRun.setFontFamily("宋体");
            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("年龄");

            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));
        }

        //插入图片
        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);
}
