CellStyle setBorder = xssfWorkbook.createCellStyle();
一、设置背景色：
setBorder.setFillForegroundColor((short) 13);// 设置背景色
setBorder.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);
二、设置边框:
setBorder.setBorderBottom(HSSFCellStyle.BORDER_THIN); //下边框
setBorder.setBorderLeft(HSSFCellStyle.BORDER_THIN);//左边框
setBorder.setBorderTop(HSSFCellStyle.BORDER_THIN);//上边框
setBorder.setBorderRight(HSSFCellStyle.BORDER_THIN);//右边框
三、设置居中:
setBorder.setAlignment(HSSFCellStyle.ALIGN_CENTER); // 居中
四、设置字体:
Font font = xssfWorkbook.createFont();
font.setColor(HSSFColor.GREEN.index);
font.setFontName("黑体");
font.setFontHeightInPoints((short) 16);//设置字体大小
font.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);//粗体显示
font.setFontHeightInPoints((short) 12);
setBorder.setFont(font);//选择需要用到的字体格式
五、设置列宽:
sheet.setColumnWidth(0, 3766); //第一个参数代表列id(从0开始),第2个参数代表宽度值
六、设置自动换行:
setBorder.setWrapText(true);//设置自动换行
注意：1，一定要在同一个workbook中，读写才能正常
2，当文本中有换行时，一定要设置此单元格样式为自动换行
