Code:
-------------------------------------------------------------------------------------

public static void main(String[] args) {
        try {
            HeaderFooter vHead = null;
            int idx = 0;
            int idy = 0;
            Cell vFirstCell = null;
            Cell vLastCell = null;
            Cell vCell = null;
            FileOutputStream fileOut = new FileOutputStream("poi-test.xlsx");
            SXSSFWorkbook workbook = new SXSSFWorkbook(100);
            SXSSFSheet worksheet = (SXSSFSheet) workbook.createSheet("POI
Worksheet");
            vHead = worksheet.getHeader();

            InputStream my_banner_image = new
FileInputStream("C:\\Users\\RATI\\Desktop\\rati.jpg");
            byte[] bytes = IOUtils.toByteArray(my_banner_image);
            int my_picture_id = workbook.addPicture(bytes,
Workbook.PICTURE_TYPE_JPEG);
            my_banner_image.close();
            CreationHelper helper = workbook.getCreationHelper();
            Drawing drawing = worksheet.createDrawingPatriarch();
            ClientAnchor anchor = helper.createClientAnchor();
            Picture pict = drawing.createPicture(anchor, my_picture_id);
            vHead.setCenter(HSSFHeader.font("Times New Roman", "Bold") +
HSSFHeader.fontSize((short) 12) + "Rati");
            vHead.setRight(HSSFHeader.font("Times New Roman", "Bold") +
HSSFHeader.fontSize((short) 8) + "&[Picture]");

            // index from 0,0... cell A1 is cell(0,0)
            Row row1 = worksheet.createRow(idx++);

            vCell = row1.createCell(idy++);
            vFirstCell = vCell;
            vCell.setCellValue("NAME1");
            vCell = row1.createCell(idy++);
            vCell.setCellValue("NAME2");
            vCell = row1.createCell(idy++);
            vCell.setCellValue("NAME3");
            vCell = row1.createCell(idy++);
            vCell.setCellValue("NAME4");
            vCell = row1.createCell(idy++);
            vCell.setCellValue("NAME5");

            idy = 0;

            row1 = worksheet.createRow(idx++);

            vCell = row1.createCell(idy++);
            vFirstCell = vCell;
            vCell.setCellValue("NAME1");
            vCell = row1.createCell(idy++);
            vCell.setCellValue("NAME2");
            vCell = row1.createCell(idy++);
            vCell.setCellValue("NAME3");
            vCell = row1.createCell(idy++);
            vCell.setCellValue("NAME4");
            vCell = row1.createCell(idy++);
            vCell.setCellValue("NAME5");

            for (int i = 0; i < 100; i++) {

                row1 = worksheet.createRow(idx++);
                idy = 0;
                for (int j = 0; j < 5; j++) {
                    vCell = row1.createCell(idy++);
                    vCell.setCellValue("TEST--" + i + "--DATA--" + j);
                    vLastCell = vCell;
                }
            }

            for (int i = 0; i < 5; i++) {
                // worksheet.autoSizeColumn(i);
            }

            worksheet.setAutoFilter(new CellRangeAddress(1, 101, 0, 4));
            workbook.write(fileOut);
            fileOut.flush();
            fileOut.close();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
