Enter text to a Table Cell in a Doc file using apache poi in java

Question

Output:

I want to fill the 2nd and 4th cell of this table. what I have tried:

//got this from an answer here.
  XWPFTable table = doc.getTableArray(0);
  XWPFTableRow oldRow = table.getRow(1);         //the cell is in the second row
  XWPFParagraph paragraph = oldRow.getCell(1).addParagraph();
  XWPFParagraph paragraph1 = oldRow.getCell(3).addParagraph();
  setRun(paragraph.createRun() , "Times New Roman" , 10, "2b5079" , "I want to enter this!" , true, false); //for 2nd cell
  setRun(paragraph1.createRun() , "Times New Roman" , 10, "2b5079" , "I want to enter this too!" , true, false);//for 4th cell

private void setRun (XWPFRun run , String fontFamily , int fontSize , String colorRGB , String text , boolean bold , boolean addBreak) {
        run.setFontFamily(fontFamily);
        run.setFontSize(fontSize);
        run.setColor(colorRGB);
        run.setText(text);
        run.setBold(bold);
        if (addBreak)
            run.addBreak();
    }

I also tried two or more similar ways to accomplish this but no luck. Why can't we just do cell(1).setText("Hello World")? (This is not working)

What is the way to do this? Thanks

I cannot confirm that XWPFTableCell.setText does not work. For me it works using current apache poi 4.1.2.

Let's have a complete example:

My WordTableExample.docx looks like this:

Then this code:

import java.io.FileInputStream;
import java.io.FileOutputStream;

import org.apache.poi.xwpf.usermodel.*;

public class WordFillTableCells {

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

  XWPFDocument document = new XWPFDocument(new FileInputStream("./WordTableExample.docx"));

  XWPFTable table = document.getTableArray(0);
  XWPFTableRow row = table.getRow(1);
  XWPFTableCell cell = row.getCell(1);
  cell.setText("New content of cell row 2 cell 2.");

  cell = row.getCell(3);
  cell.setText("New content of cell row 2 cell 4.");

  FileOutputStream out = new FileOutputStream("./WordTableExampleNew.docx");
  document.write(out);
  out.close();
  document.close();
 }
}

produces this resulting WordTableExampleNew.docx:
