I know that probably this is late for the post, but maybe for others that want to have the code, here is something that works.

    TableModel model = raportTable.getModel();

    SXSSFWorkbook wb = new SXSSFWorkbook(-1);
    SXSSFSheet sh = wb.createSheet("Report");
    Row row = sh.createRow(0);
    for (int i = 0; i < model.getColumnCount(); i++) {
        Cell cell = row.createCell(i);
        cell.setCellValue(model.getColumnName(i));
    }

    for(int i = 0; i < model.getRowCount(); i++) {
        row = sh.createRow(i + 1);
        for(int j = 0; j < model.getColumnCount(); j++){
            Cell cell = row.createCell(j);
            cell.setCellValue(model.getValueAt(i,j).toString());
        }
    }

    try {
        FileOutputStream excel = new FileOutputStream(filename + ".xlsx");
        wb.write(excel);
        excel.flush();
        excel.close();
    } catch (FileNotFoundException ex) {
        Logger.getLogger(MainForm.class.getName()).log(Level.SEVERE, null, ex);
    } catch (IOException ex) {
        Logger.getLogger(MainForm.class.getName()).log(Level.SEVERE, null, ex);
    }

Hope it helps.
