我试图使用 Apache poi XWPF 创建一个 word 文档。在文档中，我试图在特定表格单元格中创建多个嵌套表格。

我使用我的代码并成功在一个表格单元格中创建了一个表格。但是当我试图在这个特定的单元格中创建更多表时，我的代码中有一个错误点说“java.lang.IndexOutOfBoundsException：”

        XWPFTableRow tableRowFive = table.createRow();
        cell = tableRowFive.getCell(0);

        paragraph = cell.getParagraphs().get(0);
        XWPFRun run1 = paragraph.createRun();
        run1.setText("Brief facts:");

        XWPFParagraph paragraph2 = cell.addParagraph();
        XWPFRun run2 = paragraph2.createRun();
        XWPFRun run3 = paragraph2.createRun();
        run2.setText("COMPLAINANT");
        run3.setText("test");   
        XWPFParagraph paragraph3 = cell.addParagraph();
        run2 = paragraph3.createRun();
        run3 = paragraph3.createRun();
        run2.setText("tst");
        run3.setText("test2");  

        XmlCursor cursor = cell.getParagraphs().get(0).getCTP().newCursor();
        //add the nested Table1
        XWPFTable nestedTable = cell.insertNewTbl(cursor);
        XmlCursor cursor2 =cell.getParagraphs().get(1).getCTP().newCursor();
        //add the nested Table2
        XWPFTable nestedTable2 = cell.insertNewTbl(cursor2);
        XmlCursor cursor3 =cell.getParagraphs().get(2).getCTP().newCursor();
        //add the nested Table3
        XWPFTable nestedTable3 = cell.insertNewTbl(cursor3);

错误发生在最后一次创建表时。对于嵌套的 Table1 和 Table2 ，创建是可以的。但最后一个表创建“XWPFTable nestedTable3 = cell.insertNewTbl(cursor3);” 报告我错误

也许您应该使用 cursor.toNextSibling() 而不是创建新段落和新光标：

 public static void main(String[] args) throws Exception {
    FileOutputStream out = new FileOutputStream(new File("word.docx"));
    XWPFDocument document = new XWPFDocument();

    XWPFTable tableOne = document.createTable(2,2);
    XWPFTableRow tablerow = tableOne.getRow(0);
    tablerow.getCell(0).setText("Test");
    tablerow.getCell(1).setText("Test");

    tablerow = tableOne.getRow(1);
    tablerow.getCell(0).setText("Test");

    XWPFParagraph paragraph = tablerow.getCell(1).getParagraphs().get(0);
    XmlCursor cursor = paragraph.getCTP().newCursor();
    XWPFTable tableTwo = tablerow.getCell(1).insertNewTbl(cursor);

    tablerow = tableTwo.createRow();
    tablerow.createCell().setText("aaaaa");
    tablerow.createCell().setText("bbbbb");
    tablerow = tableTwo.createRow();
    tablerow.getCell(0).setText("cccc");
    tablerow.getCell(1).setText("dddd");

    tablerow = tableOne.getRow(1);
    cursor.toNextSibling();
    XWPFTable tableThree = tablerow.getCell(1).insertNewTbl(cursor);

    tablerow = tableThree.createRow();
    tablerow.createCell().setText("eeee");
    tablerow.createCell().setText("ffff");
    tablerow = tableThree.createRow();
    tablerow.getCell(0).setText("gggg");
    tablerow.getCell(1).setText("hhhh");

    document.write(out);
    out.close();

}
