<%page import="org.apache.poi.hssf.usermodel.HSSFWorkbook"%>
<%page contentType="application/vnd.ms-excel" %>
<%page import="java.io.*" %>
<%page import="java.util.*" %>

try{
  HSSFWorkbook hwb = new HSSFWorkbook();
  HSSFSheet sheet = hwb.createSheet("new sheet");
  sheet.groupRow410 );
  sheet.groupRow516);
  sheet.groupRow1315 );
  sheet.groupColumn( (short)4(short));
  sheet.groupColumn( (short)5(short)14 );
  sheet.groupColumn( (short)14(short)14 );
    sheet.setColumnGroupCollapsed( (short)4true );
 FileOutputStream fileOut = new FileOutputStream
