XSSFWorkbook基本用法

	// 创建工作簿
	XSSFWorkbook xssfWorkbook = new XSSFWorkbook();
	// 创建单元格风格样式
    XSSFCellStyle cellStyle = xssfWorkbook.createCellStyle();
	// 设置样式-单元格边框
    cellStyle.setBorderBottom(BorderStyle.THIN);
    cellStyle.setBorderLeft(BorderStyle.THIN);
    cellStyle.setBorderRight(BorderStyle.THIN);
    cellStyle.setBorderTop(BorderStyle.THIN);
    cellStyle.setAlignment(HorizontalAlignment.CENTER);
    cellStyle.setVerticalAlignment(VerticalAlignment.CENTER);
    cellStyle.setWrapText(true);
    // 创建sheet页
    XSSFSheet sheet = xssfWorkbook.createSheet();
    // 创建行数据
    XSSFRow row = sheet.createRow(0);
    // 创建单元格
    XSSFCell cell = row.createCell(0);
    // 设置单元格样式
    cell.setCellStyle(cellStyle);
