一、设置单元格对齐方式:

1 /** 2 * 设置单元格对齐方式 3 */ 4 public static void main(String[] args) throws Exception { 5 Workbook wb = new HSSFWorkbook(); //定义一个新的工作簿 6 Sheet sheet = wb.createSheet("第一个sheet页"); 7 Row row = sheet.createRow(2); //创建第3行 8 row.setHeightInPoints(30); //设置行高 9 10 createCell(wb, row, (short)0, HSSFCellStyle.ALIGN_CENTER, HSSFCellStyle.VERTICAL_BOTTOM); 11 createCell(wb, row, (short)1, HSSFCellStyle.ALIGN_FILL, HSSFCellStyle.VERTICAL_CENTER); 12 createCell(wb, row, (short)2, HSSFCellStyle.ALIGN_LEFT, HSSFCellStyle.VERTICAL_TOP); 13 createCell(wb, row, (short)3, HSSFCellStyle.ALIGN_RIGHT, HSSFCellStyle.VERTICAL_TOP); 14 15 FileOutputStream fileOut = new FileOutputStream("E:\工作簿.xls"); 16 wb.write(fileOut); 17 fileOut.close(); 18 } 19 /** 20 * 创建一个单元格并为其设置指定的对齐方式 21 * @param wb 工作簿 22 * @param row 行 23 * @param column 列 24 * @param halign 水平方向对齐方式 25 * @param valign 垂直方向对齐方式 26 */ 27 @SuppressWarnings("unused") 28 private static void createCell(Workbook wb, Row row, short column, short halign, short valign){ 29 Cell cell = row.createCell(column); //创建单元格 30 cell.setCellValue(new HSSFRichTextString("Align It")); //设置值 31 CellStyle cellStyle = wb.createCellStyle(); //创建单元格样式 32 cellStyle.setAlignment(halign); //设置单元格水平方向对齐方式 33 cellStyle.setVerticalAlignment(valign); //设置单元格垂直方向对齐方式 34 cell.setCellStyle(cellStyle); 35 }
二、设置单元格边框样式

1 /** 2 * 设置单元格边框样式 3 */ 4 public static void main(String[] args) throws Exception { 5 Workbook wb = new HSSFWorkbook(); 6 Sheet sheet = wb.createSheet("sheet1"); 7 Row row = sheet.createRow(1); 8 Cell cell = row.createCell(1); 9 cell.setCellValue(4); 10 11 CellStyle cellStyle = wb.createCellStyle(); 12 cellStyle.setBorderBottom(CellStyle.BORDER_THIN); //底部边框 13 cellStyle.setBottomBorderColor(IndexedColors.BLACK.getIndex()); //底部边框颜色 14 15 cellStyle.setBorderLeft(CellStyle.BORDER_THIN); //左边边框 16 cellStyle.setLeftBorderColor(IndexedColors.GREEN.getIndex()); //左边边框颜色 17 18 cellStyle.setBorderRight(CellStyle.BORDER_THIN); 19 cellStyle.setRightBorderColor(IndexedColors.BLUE.getIndex()); 20 21 cellStyle.setBorderTop(CellStyle.BORDER_MEDIUM_DASHED); 22 cellStyle.setTopBorderColor(IndexedColors.BLACK.getIndex()); 23 24 cell.setCellStyle(cellStyle); 25 FileOutputStream fileOut = new FileOutputStream("E:\工作簿.xls"); 26 wb.write(fileOut); 27 fileOut.close(); 28 }
三、设置单元格填充色和颜色操作

1 /** 2 * 设置单元格填充色和颜色操作 3 */ 4 public static void main(String[] args) throws Exception { 5 Workbook wb = new HSSFWorkbook(); 6 Sheet sheet = wb.createSheet("sheet1"); 7 Row row = sheet.createRow(1); 8 9 Cell cell=row.createCell(1); 10 cell.setCellValue("XX"); 11 CellStyle cellStyle=wb.createCellStyle(); 12 cellStyle.setFillBackgroundColor(IndexedColors.AQUA.getIndex()); // 背景色 13 cellStyle.setFillPattern(CellStyle.BIG_SPOTS); 14 cell.setCellStyle(cellStyle); 15 16 17 Cell cell2=row.createCell(2); 18 cell2.setCellValue("YYY"); 19 CellStyle cellStyle2=wb.createCellStyle(); 20 cellStyle2.setFillForegroundColor(IndexedColors.RED.getIndex()); //前景色 21 cellStyle2.setFillPattern(CellStyle.SOLID_FOREGROUND); 22 cell2.setCellStyle(cellStyle2); 23 24 FileOutputStream fileOut = new FileOutputStream("E:\工作簿.xls"); 25 wb.write(fileOut); 26 fileOut.close(); 27 }
四、设置单元格合并

1 /** 2 * 设置单元格合并 3 */ 4 public static void main(String[] args) throws Exception { 5 Workbook wb = new HSSFWorkbook(); 6 Sheet sheet = wb.createSheet("sheet1"); 7 Row row = sheet.createRow(1); 8 9 Cell cell=row.createCell(1); 10 cell.setCellValue("单元格合并测试"); 11 12 sheet.addMergedRegion(new CellRangeAddress( 13 1, // 起始行 14 2, //结束行 15 1, //起始列 16 2 //结束列 17 )); 18 19 FileOutputStream fileOut = new FileOutputStream("E:\工作簿.xls"); 20 wb.write(fileOut); 21 fileOut.close(); 22 }
