如何用JAVA增加word文件中表格的宽度

Question

I working on a small project where I am creating word file by Java and enter some detail in this word file. I am able to create word file and also able to enter data into it. I also write a table into word file and enter some details.

Now what I want, I want to increase width of specific column.

Is there any way to do this? I am using Apache POI drivers for creating word file and writing data into it.

I am using below code:

XWPFDocument document= new XWPFDocument();
try{
FileOutputStream out = new FileOutputStream(
new File("d:\\createparagraph.docx"));

 XWPFParagraph paragraph = document.createParagraph();
     XWPFTable table = document.createTable();
     XWPFTableRow tableRowOne = table.getRow(0);
     tableRowOne.getCell(0).setText("CLientID");   
     tableRowOne.addNewTableCell().setText(txtCID.getText());
  //create second row
    XWPFTableRow tableRow2 = table.createRow();
    tableRow2.getCell(0).setText("AccountID");
    tableRow2.getCell(1).setText(txtAID.getText());
document.write(out);
out.close();
 }

This code working fine and generate normal table but I want to increase width of specific column (Column 2).

Please help.

As far as I see, the column width settings are not implemented (as of POI version 3.15 final) in XWPFTable . So we must use the underlying low level objects.

Example:

import java.io.FileOutputStream;

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

import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTTblWidth;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.STTblWidth;

import java.math.BigInteger;

public class CreateWordTableColumnWidth {

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

  XWPFDocument document= new XWPFDocument();

  XWPFParagraph paragraph = document.createParagraph();
  XWPFRun run=paragraph.createRun();  
  run.setText("The Body:");

  paragraph = document.createParagraph();

  XWPFTable table = document.createTable(1, 2);

  //values are in unit twentieths of a point (1/1440 of an inch)
  table.setWidth(5*1440); //should be 5 inches width

  //create CTTblGrid for this table with widths of the 2 columns. 
  //necessary for Libreoffice/Openoffice to accept the column widths.
  //first column = 2 inches width
  table.getCTTbl().addNewTblGrid().addNewGridCol().setW(BigInteger.valueOf(2*1440));
  //other columns (only one in this case) = 3 inches width
  for (int col = 1 ; col < 2; col++) {
   table.getCTTbl().getTblGrid().addNewGridCol().setW(BigInteger.valueOf(3*1440));
  }

  //set width for first column = 2 inches
  CTTblWidth tblWidth = table.getRow(0).getCell(0).getCTTc().addNewTcPr().addNewTcW();
  tblWidth.setW(BigInteger.valueOf(2*1440));
  //STTblWidth.DXA is used to specify width in twentieths of a point.
  tblWidth.setType(STTblWidth.DXA);

  //set width for second column = 3 inches
  tblWidth = table.getRow(0).getCell(1).getCTTc().addNewTcPr().addNewTcW();
  tblWidth.setW(BigInteger.valueOf(3*1440));
  tblWidth.setType(STTblWidth.DXA);

  XWPFTableRow tableRowOne = table.getRow(0);
  tableRowOne.getCell(0).setText("CLientID");   
  tableRowOne.getCell(1).setText("CID001");
  //create second row
  XWPFTableRow tableRow2 = table.createRow();
  tableRow2.getCell(0).setText("AccountID");
  tableRow2.getCell(1).setText("ACCID001");

  paragraph = document.createParagraph();

  document.write(new FileOutputStream("CreateWordTableColumnWidth.docx"));
  document.close();

 }
}

The code is commented to describe what it does. Especially mentioned should be the special measurement unit Twip (twentieth of a point).
