HSSFRow row = sheet.createRow(0)

HSSFCell cell1 = row.createCell(0);

HSSFCellStyle style = workbook.createCellStyle();

// 边框设置
style.setBorderBottom(BorderStyle.THIN);

style.setBorderLeft(BorderStyle.THIN);

style.setBorderRight(BorderStyle.THIN);
style.setBorderTop(BorderStyle.THIN);
style.setVerticalAlignment(VerticalAlignment.CENTER);
// 字体居中
