java - XWPF - remove cell text -

i have .docx file contains single table. want remove text rows 2 end. method mytable.getrow(somecounter).getcell(somecounter2).settext("") doesn't work concatenates " " existing value. tried making xwpfrun , doing run.settext("") created mytable.getrow(sc).getcell(sc2).getparagraphs().get(0).createrun() doesn't work aswell.

also tried solution this thread, no luck time :(

any ideas how remove text cell? idea make new table scratch , fill content seems arduous.

your requirement "to remove text rows 2 end" little bit complicated fulfil since word table cell can contain other things text.

consider following table:

so if requirement remove all content rows 2 end, replace cells new clean ones. or @ least ones have empty paragraph in it.

this needs full ooxml-schemas-1.3.jar mentioned in https://poi.apache.org/faq.html#faq-n10025 since ctrowimpl not shipped poi-ooxml-schemas-3.13-*.jar.

without full ooxml-schemas-1.3.jar remove rows except first 1 , add new ones.

import java.io.fileoutputstream; import java.io.fileinputstream;  import java.util.list;  import org.apache.poi.xwpf.usermodel.*;  public class wordcleantablerows2 {   public static void main(string[] args) throws exception {    fileinputstream fis = new fileinputstream("document.docx");   xwpfdocument doc = new xwpfdocument(fis);    list<xwpftable> tables = doc.gettables();   xwpftable table = tables.get(0);    xwpftablerow[] rows = table.getrows().toarray(new xwpftablerow[0]);   (int r = 0; r < rows.length; r++) {    if (r > 0) {     xwpftablerow row = rows[r];     table.removerow(1); //remove second row. others shift upwards     table.createrow(); //add new row @ end    }   }    doc.write(new fileoutputstream("new document.docx"));   } } 

edit:

the following should work without ooxml-schemas-1.3.jar , same first example.

the org.openxmlformats.schemas.wordprocessingml.x2006.main.ctp shipped poi-ooxml-schemas-3.13-*.jar.
