poi的样式设置

样式设置：
    HSSFSheet sheet = workbook.createSheet("sheetName");    //创建sheet  
    sheet.setVerticallyCenter(true);  
      
    //下面样式可作为导出左右分栏的表格模板  
    sheet.setColumnWidth((short) 0, (short) 2600);// 设置列宽  
    sheet.setColumnWidth((short) 1, (short) 2400);  
    sheet.setColumnWidth((short) 2, (short) 2300);  
    sheet.setColumnWidth((short) 3, (short) 1600);  
    sheet.setColumnWidth((short) 4, (short) 1800);  
    sheet.setColumnWidth((short) 5, (short) 1000);// 空列设置小一些  
    sheet.setColumnWidth((short) 6, (short) 2600);// 设置列宽  
    sheet.setColumnWidth((short) 7, (short) 2400);  
    sheet.setColumnWidth((short) 8, (short) 2300);  
    sheet.setColumnWidth((short) 9, (short) 1600);  
    sheet.setColumnWidth((short) 10, (short) 1800);  
      
    HSSFCellStyle cellstyle = (HSSFCellStyle) workbook.createCellStyle();// 设置表头样式  
    cellstyle.setAlignment(HSSFCellStyle.ALIGN_CENTER);// 设置居中  
      
    HSSFCellStyle headerStyle = (HSSFCellStyle) workbook .createCellStyle();// 创建标题样式  
    headerStyle.setVerticalAlignment(HSSFCellStyle.VERTICAL_CENTER);    //设置垂直居中

    HSSFFont headerFont = (HSSFFont) workbook.createFont(); //创建字体样式  
    headerFont.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD); // 字体加粗  
    headerFont.setFontName("Times New Roman");  //设置字体类型  
    headerFont.setFontHeightInPoints((short) 8);    //设置字体大小  
    headerStyle.setFont(headerFont);    //为标题样式设置字体样式  
      
    HSSFCellStyle headerStyle1 = (HSSFCellStyle) workbook .createCellStyle();// 创建标题样式1

    headerStyle2.setAlignment(HSSFCellStyle.ALIGN_CENTER);  
    HSSFFont headerFont2 = (HSSFFont) workbook.createFont();  
    headerFont2.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);// 字体加粗  
    headerFont2.setFontName("Times New Roman");  
    headerFont2.setFontHeightInPoints((short) 8);  
    headerStyle2.setFont(headerFont2);  
    headerStyle2.setBorderBottom(HSSFCellStyle.BORDER_THIN); // 下边框  
    headerStyle2.setBorderLeft(HSSFCellStyle.BORDER_THIN);// 左边框

    headerStyle2.setBorderRight(HSSFCellStyle.BORDER_THIN);// 右边框  
      
    HSSFCellStyle cell_Style = (HSSFCellStyle) workbook .createCellStyle();// 设置字体样式  
    cell_Style.setAlignment(HSSFCellStyle.ALIGN_CENTER);

    HSSFRow row = sheet.createRow((short)1);    //创建行  
    HSSFCell cell = row.createCell((short)1);   //创建列  
    cell.setCellStyle(headerStyle2);    //单元格引用样式
