//生成excel Workbook wb = new HSSFWorkbook(); Sheet sheet = wb.createSheet(); FileOutputStream fos = new FileOutputStream("c:\\1.xls"); Row row = sheet.createRow(0); Cell cell = row.createCell(0); CellStyle style =wb.createCellStyle(); //6.1创建字体 Font font = wb.createFont(); font.setFontHeightInPoints((short) 36); font.setFontName("华文琥珀"); font.setColor(Font.COLOR_RED); style.setFont(font); cell.setCellStyle(style); cell.setCellValue("混合过关"); wb.write(fos); fos.close();
sheet.setColumnWidth(0, 10000); sheet.setColumnWidth(1, 10000);
HSSFWorkbook wb = new HSSFWorkbook(); HSSFSheet sheet = wb.createSheet(); HSSFCellStyle setBorder = wb.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: HSSFFont font = wb.createFont(); font.setFontName("黑体"); font.setFontHeightInPoints((short) 16);//设置字体大小 HSSFFont font2 = wb.createFont(); font2.setFontName("仿宋_GB2312"); font2.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);//粗体显示 font2.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 七、合并单元格: Region region1 = new Region(0, (short) 0, 0, (short) 6); //参数1:行号 参数2:起始列号 参数3:行号 参数4:终止列号 sheet.addMergedRegion(region1); 或者用 CellRangeAddress region1 = new CellRangeAddress(rowNumber, rowNumber, (short) 0, (short) 11); 但应注意两个构造方法的参数不是一样的,具体使用哪个取决于POI的不同版本。 sheet.addMergedRegion(region1); 目前用过的就这么多,后续有新的会继续添加。 八、加边框 HSSFCellStyle cellStyle= wookBook.createCellStyle(); cellStyle.setAlignment(HSSFCellStyle.ALIGN_CENTER); cellStyle.setBorderBottom(HSSFCellStyle.BorderBORDER_MEDIUM); cellStyle.setBottomBorderColor(HSSFColor.BLACK.index); cellStyle.setBorderLeft(HSSFCellStyle.BORDER_MEDIUM); cellStyle.setLeftBorderColor(HSSFColor.BLACK.index); cellStyle.setBorderRight(HSSFCellStyle.BORDER_MEDIUM); cellStyle.setRightBorderColor(HSSFColor.BLACK.index); cellStyle.setBorderTop(HSSFCellStyle.BORDER_MEDIUM); cellStyle.setTopBorderColor(HSSFColor.BLACK.index); 九、字体颜色
中号线
小号线
//BORDER_MEDIUM中号的线 //BORDER_THIN小号的线 CellStyle style = wb.createCellStyle(); style.setBorderBottom(CellStyle.BORDER_THIN); style.setBottomBorderColor(IndexedColors.BLACK.getIndex()); style.setBorderLeft(CellStyle.BORDER_THIN); style.setLeftBorderColor(IndexedColors.BLACK.getIndex()); style.setBorderRight(CellStyle.BORDER_THIN); style.setRightBorderColor(IndexedColors.BLACK.getIndex()); style.setBorderTop(CellStyle.BORDER_THIN); style.setTopBorderColor(IndexedColors.BLACK.getIndex()); // cell.setCellStyle(style);
