//生成excel

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);
