1、生成Workbook

//生成WorkbookHSSFWorkbook wb = new HSSFWorkbook();//添加Worksheet（不添加sheet时生成的xls文件打开时会报错）@SuppressWarnings("unused")Sheet sheet1 = wb.createSheet();@SuppressWarnings("unused")Sheet sheet2 = wb.createSheet();@SuppressWarnings("unused")Sheet sheet3 = wb.createSheet("new sheet");@SuppressWarnings("unused")Sheet sheet4 = wb.createSheet("rensanning");//保存为Excel文件FileOutputStream out = null;try {    out = new FileOutputStream("c:\\text.xls");    wb.write(out);		} catch (IOException e) {    System.out.println(e.toString());} finally {    try {        out.close();    } catch (IOException e) {        System.out.println(e.toString());    }}	

2、生成Workbook OOXML形式(.xlsx)

//生成WorkbookXSSFWorkbook wb = new XSSFWorkbook();//......

3、打开Workbook

//方法一：使用WorkbookFactoryFileInputStream in = null;Workbook wb = null;try {	in = new FileInputStream(TEST_WORKBOOK_NAME);	wb = WorkbookFactory.create(in);} catch (IOException e) {	System.out.println(e.toString());} catch (InvalidFormatException e) {	System.out.println(e.toString());} finally {	try {		in.close();	} catch (IOException e) {		System.out.println(e.toString());	}}System.out.println("====================Workbook====================");System.out.println("Number of Sheets:" + wb.getNumberOfSheets());System.out.println("Sheet3's name:" + wb.getSheetName(3));System.out.println();//方法二：使用POIFSFileSystemtry {	in = new FileInputStream(TEST_WORKBOOK_NAME);	POIFSFileSystem fs = new POIFSFileSystem(in);	wb = new HSSFWorkbook(fs);} catch (IOException e) {	System.out.println(e.toString());} finally {	try {		in.close();	} catch (IOException e) {		System.out.println(e.toString());	}}System.out.println("====================Workbook====================");System.out.println("Number of Sheets:" + wb.getNumberOfSheets());System.out.println("Sheet3's name:" + wb.getSheetName(3));System.out.println();

4、打开加密的Workbook(读加密)

FileInputStream input = new FileInputStream(TEST_WORKBOOK_NAME_ENCRYPTED);BufferedInputStream binput = new BufferedInputStream(input);POIFSFileSystem poifs = new POIFSFileSystem(binput);Biff8EncryptionKey.setCurrentUserPassword(TEST_WORKBOOK_PASSWORD);HSSFWorkbook wb = new HSSFWorkbook(poifs);System.out.println("====================EncryptedWorkbook====================");System.out.println("Number of Sheets:" + wb.getNumberOfSheets());System.out.println("Sheet0's name:" + wb.getSheetName(0));System.out.println();

Sheet sheet = wb.createSheet("append sheet");

wb.cloneSheet(1);

wb.setSheetName(i, "SheetName new");

8、删除Sheet

wb.removeSheetAt(1);

//设置下部Sheet名的Tab的第一个可见Tab（以左的Sheet看不见）wb.setFirstVisibleTab(2);

wb.setSheetOrder("SheetName3", 1);wb.setSheetOrder(wb.getSheetName(4), 0);

11、设置当前Sheet

//设置当前Sheetwb.setActiveSheet(wb.getNumberOfSheets() - 1);//（Excel的当前Sheet被设置，需要结合setSelected使用，不然下部Sheet名的Tab还是默认为第一个）//（需要选择多个Sheet的话，每个Sheet调用setSelected(true)即可）wb.getSheetAt(wb.getNumberOfSheets() - 1).setSelected(true);

12、固定窗口

wb.getSheet("SheetName4").createFreezePane(2, 2);

13、分割窗口

wb.getSheet("SheetName5").createSplitPane(2000, 2000, 0, 0, HSSFSheet.PANE_LOWER_LEFT);

14、Sheet缩放

//setZoom(int numerator, int denominator)//"numerator"÷"denominator"  例如： 3÷1＝3 那就是设置为300%//扩大(200%)wb.getSheet("sheetname1").setZoom(2, 1);//缩小(50%)wb.getSheet("sheetname2").setZoom(1, 2);

15、行列分组

wb.getSheet("sheetname3").groupColumn(4, 7);wb.getSheet("sheetname3").groupColumn(9, 12);wb.getSheet("sheetname3").groupColumn(10, 11);wb.getSheet("sheetname3").groupRow(5, 14);wb.getSheet("sheetname3").groupRow(7, 13);wb.getSheet("sheetname3").groupRow(16, 19);

16、关闭分组

wb.getSheet("sheetname3").setColumnGroupCollapsed(10, true);wb.getSheet("sheetname3").setRowGroupCollapsed(7, true);

17、插入行

Row row1 = wb.getSheet("sheetname4").createRow(1);Cell cell1_1 = row1.createCell(1);cell1_1.setCellValue(123);Row row4 = wb.getSheet("sheetname4").createRow(4);Cell cell4_3 = row4.createCell(3);cell4_3.setCellValue("中国");

Row row = wb.getSheet("sheetname4").getRow(1);wb.getSheet("sheetname4").removeRow(row);

19、移动行

//******移动行只移动内容，不牵扯行的删除和插入//移动行（把第1行和第2行移到第5行之后）wb.getSheet("sheetname5").shiftRows(0, 1, 5);//移动行（把第3行和第4行往上移动1行）wb.getSheet("sheetname5").shiftRows(2, 3, -1);

//设置默认行高wb.getSheet("sheetname6").setDefaultRowHeight((short)100);//设置行高wb.getSheet("sheetname6").getRow(2).setHeight((short)(100 * 20));

//设置默认列宽wb.getSheet("sheetname7").setDefaultColumnWidth(12);//设置列宽wb.getSheet("sheetname7").setColumnWidth(0, 5 * 256);

//不显示网格线wb.getSheet("sheetname8").setDisplayGridlines(false);

23、设置分页

//设置第一页：3行2列 （可以多次设置）wb.getSheet("sheetname9").setRowBreak(2);wb.getSheet("sheetname9").setColumnBreak(1);

24、添加，删除，合并单元格

//追加行for (int i = 0; i < 10; i++) {    Row row = wb.getSheet("sheetname10").createRow(i);    for (int j = 0; j < 10; j++) {    	//添加单元格	    Cell cell = row.createCell(j);	    cell.setCellValue(i + 1);    }        //删除单元格    row.removeCell(row.getCell(5));}	    //合并单元格//CellRangeAddress(int firstRow, int lastRow, int firstCol, int lastCol)wb.getSheet("sheetname10").addMergedRegion(new CellRangeAddress(1, 4, 2, 3));

25、设置Header，Footer

//HeaderHeader header = wb.getSheet("sheetname11").getHeader();header.setLeft(HSSFHeader.startUnderline() +        HSSFHeader.font("宋体", "Italic") +        "文字文字" +        HSSFHeader.endUnderline());header.setCenter(HSSFHeader.fontSize((short)16) +        HSSFHeader.startDoubleUnderline() +        HSSFHeader.startBold() +        "汉字汉字" +        HSSFHeader.endBold() +        HSSFHeader.endDoubleUnderline());header.setRight("打印时间:" + HSSFHeader.date() +  " " + HSSFHeader.time());//FooterFooter footer = wb.getSheet("sheetname11").getFooter();footer.setLeft("Copyright @ rensanning");footer.setCenter("Page:" + HSSFFooter.page() + " / " + HSSFFooter.numPages());footer.setRight("File:" + HSSFFooter.file());

26、设置单元格值

//booleanCell cell00 = rows[0].createCell(0);boolean val00 = true;cell00.setCellValue(val00);//Calendar 格式化CellStyle styleCalendar = wb.createCellStyle();DataFormat formatCalendar = wb.createDataFormat();styleCalendar.setDataFormat(formatCalendar.getFormat("yyyy/mm/dd"));Cell cell11 = rows[1].createCell(0);Calendar val11 = Calendar.getInstance();cell11.setCellStyle(styleCalendar);cell11.setCellValue(val11);//Date 格式化CellStyle styleDate = wb.createCellStyle();DataFormat formatDate = wb.createDataFormat();styleDate.setDataFormat(formatDate.getFormat("yyyy/mm/dd hh:mm"));Cell cell21 = rows[2].createCell(0);Date val21 = new Date();cell21.setCellStyle(styleDate);cell21.setCellValue(val21);//doubleCell cell30 = rows[3].createCell(0);double val30 = 1234.56;cell30.setCellValue(val30);//double 格式化CellStyle styleDouble = wb.createCellStyle();DataFormat formatDouble = wb.createDataFormat();styleDouble.setDataFormat(formatDouble.getFormat("#,##0.00"));Cell cell31 = rows[3].createCell(1);double val31 = 1234.56;cell31.setCellStyle(styleDouble);cell31.setCellValue(val31);//StringCell cell40 = rows[4].createCell(0);HSSFRichTextString val40 = new HSSFRichTextString("Test汉字");cell40.setCellValue(val40);

27、设置单元格边线

wb.getSheet("sheetname2").setColumnWidth(1, 4096);Row row1 = wb.getSheet("sheetname2").createRow(1);row1.setHeightInPoints(70);Cell cell1_1 = row1.createCell(1);cell1_1.setCellValue("Sample");CellStyle style = wb.createCellStyle();style.setBorderTop(CellStyle.BORDER_DASHED);style.setBorderBottom(CellStyle.BORDER_DOUBLE);style.setBorderLeft(CellStyle.BORDER_MEDIUM_DASH_DOT);style.setBorderRight(CellStyle.BORDER_MEDIUM);style.setTopBorderColor(IndexedColors.MAROON.getIndex());style.setBottomBorderColor(IndexedColors.SKY_BLUE.getIndex());style.setLeftBorderColor(IndexedColors.ORANGE.getIndex());style.setRightBorderColor(IndexedColors.BLUE_GREY.getIndex());cell1_1.setCellStyle(style);

wb.getSheet("sheetname3").setColumnWidth(0, 4096);wb.getSheet("sheetname3").setColumnWidth(1, 4096);wb.getSheet("sheetname3").setColumnWidth(2, 4096);Row row1 = wb.getSheet("sheetname3").createRow(1);row1.setHeightInPoints(70);Cell cell1_0 = row1.createCell(0);Cell cell1_1 = row1.createCell(1);Cell cell1_2 = row1.createCell(2);cell1_0.setCellValue("THIN_VERT_BANDS");cell1_1.setCellValue("BIG_SPOTS");cell1_2.setCellValue("THICK_HORZ_BANDS");CellStyle style1 = wb.createCellStyle();style1.setFillPattern(CellStyle.THIN_VERT_BANDS);style1.setFillForegroundColor(IndexedColors.WHITE.getIndex());style1.setFillBackgroundColor(IndexedColors.BLUE.getIndex());CellStyle style2 = wb.createCellStyle();style2.setFillPattern(CellStyle.BIG_SPOTS);style2.setFillForegroundColor(IndexedColors.RED.getIndex());style2.setFillBackgroundColor(IndexedColors.WHITE.getIndex());CellStyle style3 = wb.createCellStyle();style3.setFillPattern(CellStyle.THICK_HORZ_BANDS);style3.setFillForegroundColor(IndexedColors.PINK.getIndex());style3.setFillBackgroundColor(IndexedColors.BROWN.getIndex());cell1_0.setCellStyle(style1);cell1_1.setCellStyle(style2);cell1_2.setCellStyle(style3);

29、设置单元格注释

HSSFCreationHelper createHelper =    (HSSFCreationHelper)wb.getCreationHelper();Drawing patriarch = wb.getSheet("sheetname4").createDrawingPatriarch();//注释Row row = wb.getSheet("sheetname4").createRow(1);Cell cell = row.createCell(1);HSSFClientAnchor clientAnchor = new HSSFClientAnchor(0, 0, 0, 0,		(short) 4, 2, (short) 6, 5);Comment comment = patriarch.createCellComment(clientAnchor);comment.setString(createHelper.createRichTextString("注释注释111"));comment.setAuthor("rensanning");cell.setCellComment(comment);//带字体的注释Row row2 = wb.getSheet("sheetname4").createRow(2);Cell cell2 = row2.createCell(1);Font font = wb.createFont();font.setFontName("宋体");font.setFontHeightInPoints((short)10);font.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);font.setColor(HSSFColor.RED.index);Comment comment2 = patriarch.createCellComment(clientAnchor);HSSFRichTextString text = new HSSFRichTextString("注释注释222");text.applyFont(font);comment2.setString(text);comment2.setAuthor("rensanning");cell2.setCellComment(comment2);

30、设置单元格字体（斜体，粗体，下线，取消线，字体，大小，背景色）

Font font = null;CellStyle style = null;//斜体font = wb.createFont();font.setItalic(true);style = wb.createCellStyle();style.setFont(font);wb.getSheet("sheetname5").getRow(1).getCell(1).setCellStyle(style);//粗体font = wb.createFont();font.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);style = wb.createCellStyle();style.setFont(font);wb.getSheet("sheetname5").getRow(2).getCell(1).setCellStyle(style);//字体名font = wb.createFont();font.setFontName("Courier New");style = wb.createCellStyle();style.setFont(font);wb.getSheet("sheetname5").getRow(3).getCell(1).setCellStyle(style);//字体大小font = wb.createFont();font.setFontHeightInPoints((short)20);style = wb.createCellStyle();style.setFont(font);wb.getSheet("sheetname5").getRow(4).getCell(1).setCellStyle(style);//文字颜色font = wb.createFont();font.setColor(HSSFColor.YELLOW.index);style = wb.createCellStyle();style.setFont(font);wb.getSheet("sheetname5").getRow(5).getCell(1).setCellStyle(style);        //上标font = wb.createFont();font.setTypeOffset(HSSFFont.SS_SUPER);style = wb.createCellStyle();style.setFont(font);wb.getSheet("sheetname5").getRow(6).getCell(1).setCellStyle(style);//下标font = wb.createFont();font.setTypeOffset(HSSFFont.SS_SUB);style = wb.createCellStyle();style.setFont(font);wb.getSheet("sheetname5").getRow(7).getCell(1).setCellStyle(style);//删除线font = wb.createFont();font.setStrikeout(true);style = wb.createCellStyle();style.setFont(font);wb.getSheet("sheetname5").getRow(8).getCell(1).setCellStyle(style);//下划线font = wb.createFont();font.setUnderline(HSSFFont.U_SINGLE);style = wb.createCellStyle();style.setFont(font);wb.getSheet("sheetname5").getRow(9).getCell(1).setCellStyle(style);//背景色style = wb.createCellStyle();style.setFillForegroundColor(HSSFColor.SEA_GREEN.index);style.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);style.setFont(font);wb.getSheet("sheetname5").getRow(10).getCell(1).setCellStyle(style);
