apache poi - How to insert a table into a cell in poi word? -

i want insert table cell,i did demo failure, can give advice?

    xwpfdocument document = new xwpfdocument();     xwpftable tabletwo = document.createtable(1,1);     xwpftablerow tabletworow1 = tabletwo.getrow(0);     tabletworow1.getcell(0).settext("aaaaaaaaaa");     xwpftable tableone = document.createtable(2,2);     xwpftablerow tableonerow1 = tableone.getrow(0);     xwpftablerow tableonerow2 = tableone.getrow(1);     tableonerow1.getcell(0).settext("test");     tableonerow1.getcell(1).settext("test");     tableonerow2.getcell(0).settext("test");     tableonerow2.getcell(1).inserttable(0, tabletwo);     fileoutputstream fos = new fileoutputstream("d:\\2.docx");     document.write(fos);     fos.close(); 

the xwpftable created using xwpfdocument.createtable belongs document. cannot later taken document , putted cell.

for doing this, xwpftablecell.insertnewtbl needed.

the following code works using actual apache poi versions:

import java.io.*;  import org.apache.poi.xwpf.usermodel.*;  public class createwordtableintable {   public static void main(string[] args) throws exception {      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).getparagrapharray(0);     xwpftable tabletwo = tablerow.getcell(1).insertnewtbl(paragraph.getctp().newcursor());      tabletwo.getcttbl().addnewtblpr().addnewtblborders().addnewleft().setval(      org.openxmlformats.schemas.wordprocessingml.x2006.main.stborder.single);     tabletwo.getcttbl().gettblpr().gettblborders().addnewright().setval(      org.openxmlformats.schemas.wordprocessingml.x2006.main.stborder.single);     tabletwo.getcttbl().gettblpr().gettblborders().addnewtop().setval(      org.openxmlformats.schemas.wordprocessingml.x2006.main.stborder.single);     tabletwo.getcttbl().gettblpr().gettblborders().addnewbottom().setval(      org.openxmlformats.schemas.wordprocessingml.x2006.main.stborder.single);     tabletwo.getcttbl().gettblpr().gettblborders().addnewinsideh().setval(      org.openxmlformats.schemas.wordprocessingml.x2006.main.stborder.single);     tabletwo.getcttbl().gettblpr().gettblborders().addnewinsidev().setval(      org.openxmlformats.schemas.wordprocessingml.x2006.main.stborder.single);      tablerow = tabletwo.createrow();     tablerow.createcell().settext("aaaaaaaaaa");     tablerow.createcell().settext("jjjjjjjj");      tablerow = tabletwo.createrow();      tablerow.getcell(0).settext("bbbbbbbbbb");      tablerow.getcell(1).settext("gggggggggg");      document.write(new fileoutputstream("createwordtableintable.docx"));     document.close();   } } 

but recommend not use approach use merged cells instead. tables contained in table cells ugly. true html word other text document formats can contain tables.
