apache poi 在word文档中添加表格

Question

我有 Java 代码来使用 Apache POI 创建一个表格和一些文本到 Word 文档，但它在最后一个文档中添加了表格。我想写一些文字，然后添加表格并再次写一些文字。

目前它添加表格第一个和最后一个文档添加 2 个文本（嗨和再见）

我的代码：

public static void main(String[] args)throws Exception {
        //Blank Document
        XWPFDocument document= new XWPFDocument();

        //Write the Document in file system
        FileOutputStream out = new FileOutputStream(
        new File("create_table.docx"));

        //create table
        XWPFTable table    = document.createTable();
        XWPFParagraph para = document.createParagraph();
        XWPFRun run        = para.createRun();

        run.setText("Hi");
        //create first row
        XWPFTableRow tableRowOne = table.getRow(0);
        tableRowOne.getCell(0).setText("col one, row one");
        tableRowOne.addNewTableCell().setText("col two, row one");
        tableRowOne.addNewTableCell().setText("col three, row one");
        //create second row
        XWPFTableRow tableRowTwo = table.createRow();
        tableRowTwo.getCell(0).setText("col one, row two");
        tableRowTwo.getCell(1).setText("col two, row two");
        tableRowTwo.getCell(2).setText("col three, row two");
        //create third row
        XWPFTableRow tableRowThree = table.createRow();
        tableRowThree.getCell(0).setText("col one, row three");
        tableRowThree.getCell(1).setText("col two, row three");
        tableRowThree.getCell(2).setText("col three, row three");

        run.setText("Bye");

        document.write(out);
        out.close();
        System.out.println("create_table.docx written successully");
}

如何打印Hi第一页并添加表格并Bye在表格后打印？

每次我想向其中添加内容并最终编写并打开它时，我该如何保存？

谢谢

您必须保持正确的顺序，更重要的是：您必须创建一个新段落。

这是代码，你需要：

public static void main(String[] args) throws IOException {

    //Blank Document
    XWPFDocument document = new XWPFDocument();

    //Write the Document in file system
    FileOutputStream out = new FileOutputStream(new File("create_table.docx"));

    //Write first Text in the beginning
    XWPFParagraph para = document.createParagraph();
    XWPFRun run = para.createRun();
    run.setText("Hi");

    //create table
    XWPFTable table = document.createTable();

    //create first row
    XWPFTableRow tableRowOne = table.getRow(0);
    tableRowOne.getCell(0).setText("col one, row one");
    tableRowOne.addNewTableCell().setText("col two, row one");
    tableRowOne.addNewTableCell().setText("col three, row one");
    //create second row
    XWPFTableRow tableRowTwo = table.createRow();
    tableRowTwo.getCell(0).setText("col one, row two");
    tableRowTwo.getCell(1).setText("col two, row two");
    tableRowTwo.getCell(2).setText("col three, row two");
    //create third row
    XWPFTableRow tableRowThree = table.createRow();
    tableRowThree.getCell(0).setText("col one, row three");
    tableRowThree.getCell(1).setText("col two, row three");
    tableRowThree.getCell(2).setText("col three, row three");

    //Write second Text after the table (by creating a new paragraph)
    XWPFParagraph para2 = document.createParagraph();
    XWPFRun run2 = para2.createRun();
    run2.setText("Bye");

    document.write(out);
    out.close();
    System.out.println("create_table.docx written successully");
}

这是输出，你会得到：
