我试图使用Apache poi XWPF来创建word文档。在文档中，我试图在特定的表格单元格中创建多个嵌套表。
我使用我的代码并在一个表格单元格中成功创建了一个表格。但是当我试图在这个特定的单元格中创建更多的表时，我的代码中有一个错误指向＆＃34; java.lang.IndexOutOfBoundsException：＆＃34;
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);
错误发生在最后一个表创建时。对于嵌套的Table1和Table2，创建是可以的。但最后一个表创建＆＃34; XWPFTable nestedTable3 = cell.insertNewTbl（cursor3）;＆＃34;报告错误

答案 0 :(得分：1)
也许您应该使用cursor.toNextSibling（）而不是创建新段落和新游标：
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();
}
