java Apache POI Word existing table insert row with cell style and formatting

Question

I'am a beginner in Apache POI and want to extend an existing table in the word template file with some rows. If I use that code below, the table will be extended with row bit the new row's cells created normal style.

My goal is the cells have the same table cells style etc (font, with, height...)

    XWPFDocument doc = new XWPFDocument(openFile(fileName));
    XWPFTable tbl = doc.getTableArray(tableIndex);
    XWPFTableRow lastRow = tbl.getRows().get(tbl.getNumberOfRows() - 1);
    cellCounter = lastRow.getTableICells().size(); 
    XWPFTableRow newRow = tbl.createRow(); 
    for (int i = 0; i < data.size() && cellCounter <= data.size(); i++) {         
    String text = data.get(i);
        XWPFTableCell cell = newRow.getCell(i);
        if (cell != null) {
            cell.setText(text);
        }
    }

Thanks for your answer. R.

The following code gets an exact copy of the second row in first table contained in document. Then it changes the text contents of the cells in this row. And then inserts this copied row between row 2 and 3 of this table.

The changing the content must be done before table.addRow since the row must be complete before inserting it in List tableRows and adding it to the TrArray of the CTTbl ctTbl. Later changings will not be written into the XML. I've not really got the reason why this is the case.

Then the code gets a copy of the last row and adds this copy at the end of the table. Here also the changing the content must be done before table.addRow.

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

import  org.openxmlformats.schemas.wordprocessingml.x2006.main.CTRow;

public class WordInsertTableRow {

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

  XWPFDocument doc = new XWPFDocument(new FileInputStream("source.docx"));

  XWPFTable table = doc.getTableArray(0);

//insert new row, which is a copy of row 2, as new row 3:
  XWPFTableRow oldRow = table.getRow(1);
  CTRow ctrow = CTRow.Factory.parse(oldRow.getCtRow().newInputStream());
  XWPFTableRow newRow = new XWPFTableRow(ctrow, table);

  int i = 1;
  for (XWPFTableCell cell : newRow.getTableCells()) {
   for (XWPFParagraph paragraph : cell.getParagraphs()) {
    for (XWPFRun run : paragraph.getRuns()) {
     run.setText("New row 3 cell " + i++, 0);
    }
   }
  }

  table.addRow(newRow, 2);

//insert new last row, which is a copy previous last row:
  XWPFTableRow lastRow = table.getRows().get(table.getNumberOfRows() - 1);
  ctrow = CTRow.Factory.parse(lastRow.getCtRow().newInputStream());
  newRow = new XWPFTableRow(ctrow, table);

  i = 1;
  for (XWPFTableCell cell : newRow.getTableCells()) {
   for (XWPFParagraph paragraph : cell.getParagraphs()) {
    for (XWPFRun run : paragraph.getRuns()) {
     run.setText("New last row cell " + i++, 0);
    }
   }
  }

  table.addRow(newRow);

  doc.write(new FileOutputStream("result.docx"));
  doc.close();

 }
}
