1、遍历workbook

代码

// load源文件
POIFSFileSystem fs = new POIFSFileSystem(new FileInputStream(filePath));
HSSFWorkbook wb = new HSSFWorkbook(fs);
for (int i = 0; i < wb.getNumberOfSheets(); i++) {
HSSFSheet sheet = wb.getSheetAt(i);
for (int i = sheet.getFirstRowNum(); i < sheet.getLastRowNum(); i ++) {
HSSFRow row = sheet.getRow(i);
if (row != null) {
。。。操作}
}
}
// 目标文件
FileOutputStream fos = new FileOutputStream(objectPath);
//写文件
swb.write(fos);
fos.close();

2、得到列和单元格

代码

HSSFRow row = sheet.getRow(i);
HSSFCell cell = row.getCell((short) j);

3、设置sheet名称和单元格内容为中文

代码

wb.setSheetName(n, "中文",HSSFCell.ENCODING_UTF_16);
cell.setEncoding((short) 1);
cell.setCellValue("中文");

4、单元格内容未公式或数值，可以这样读写

代码

cell.setCellType(HSSFCell.CELL_TYPE_NUMERIC);
cell.getNumericCellValue()

5、设置列宽、行高

代码

sheet.setColumnWidth((short)column,(short)width);
row.setHeight((short)height);

6、添加区域，合并单元格

代码

Region region = new Region((short)rowFrom,(short)columnFrom,(short)rowTo,(short)columnTo);
sheet.addMergedRegion(region);
//得到所有区域
sheet.getNumMergedRegions()

7、常用方法
根据单元格不同属性返回字符串数值

代码

public String getCellStringValue(HSSFCell cell) {
String cellValue = "";
switch (cell.getCellType()) {
case HSSFCell.CELL_TYPE_STRING:
cellValue = cell.getStringCellValue();
if(cellValue.trim().equals("")||cellValue.trim().length()<=0)
cellValue=" ";
break;
case HSSFCell.CELL_TYPE_NUMERIC:
cellValue = String.valueOf(cell.getNumericCellValue());
break;
case HSSFCell.CELL_TYPE_FORMULA:
cell.setCellType(HSSFCell.CELL_TYPE_NUMERIC);
cellValue = String.valueOf(cell.getNumericCellValue());
break;
case HSSFCell.CELL_TYPE_BLANK:
cellValue=" ";
break;
case HSSFCell.CELL_TYPE_BOOLEAN:
break;
case HSSFCell.CELL_TYPE_ERROR:
break;
default:
break;
}
return cellValue;
}

8、常用单元格边框格式

虚线HSSFCellStyle.BORDER_DOTTED
实线HSSFCellStyle.BORDER_THIN

代码

public static HSSFCellStyle getCellStyle(short type)
{
HSSFWorkbook wb = new HSSFWorkbook();
HSSFCellStyle style = wb.createCellStyle();
style.setBorderBottom(type);//下边框
style.setBorderLeft(type);//左边框
style.setBorderRight(type);//右边框
style.setBorderTop(type);//上边框
return style;
}

9、设置字体和内容位置

代码

HSSFFont f = wb.createFont();
f.setFontHeightInPoints((short) 11);//字号
f.setBoldweight(HSSFFont.BOLDWEIGHT_NORMAL);//加粗
style.setFont(f);
style.setAlignment(HSSFCellStyle.ALIGN_CENTER);//左右居中
style.setVerticalAlignment(HSSFCellStyle.VERTICAL_CENTER);//上下居中
style.setRotation(short rotation);//单元格内容的旋转的角度
HSSFDataFormat df = wb.createDataFormat();
style1.setDataFormat(df.getFormat("0.00%"));//设置单元格数据格式
cell.setCellFormula(string);//给单元格设公式
style.setRotation(short rotation);//单元格内容的旋转的角度
cell.setCellStyle(style);

10、插入图片
论坛里看到的

代码

//先把读进来的图片放到一个ByteArrayOutputStream中，以便产生ByteArray
ByteArrayOutputStream byteArrayOut = new ByteArrayOutputStream();
BufferedImage bufferImg = ImageIO.read(new File("ok.jpg"));
ImageIO.write(bufferImg,"jpg",byteArrayOut);
//读进一个excel模版
FileInputStream fos = new FileInputStream(filePathName+"/stencil.xlt");
fs = new POIFSFileSystem(fos);
//创建一个工作薄
HSSFWorkbook wb = new HSSFWorkbook(fs);
HSSFSheet sheet = wb.getSheetAt(0);
HSSFPatriarch patriarch = sheet.createDrawingPatriarch();
HSSFClientAnchor anchor = new HSSFClientAnchor(0,0,1023,255,(short) 0,0,(short)10,10);
patriarch.createPicture(anchor , wb.addPicture(byteArrayOut.toByteArray(),HSSFWorkbook.PICTURE_TYPE_JPEG));

POI操作Excel文档－基础篇（转）

liaojiyong — Wed, 14 Nov 2007 14:26:00 GMT

关键字: poi

一．POI简介

Jakarta POI 是apache的子项目，目标是处理ole2对象。它提供了一组操纵Windows文档的Java API

目前比较成熟的是HSSF接口，处理MS Excel（97-2002）对象。它不象我们仅仅是用csv生成的没有格式的可以由Excel转换的东西，而是真正的Excel对象，你可以控制一些属性如sheet,cell等等。

二．HSSF概况

HSSF 是Horrible SpreadSheet Format的缩写，也即“讨厌的电子表格格式”。也许HSSF的名字有点滑稽，就本质而言它是一个非常严肃、正规的API。通过HSSF，你可以用纯Java代码来读取、写入、修改Excel文件。

HSSF 为读取操作提供了两类API：usermodel和eventusermodel，即“用户模型”和“事件-用户模型”。前者很好理解，后者比较抽象，但操作效率要高得多。

三．开始编码

1 ．准备工作

要求:JDK 1.4+POI开发包

可以到 http://www.apache.org/dyn/closer.cgi/jakarta/poi/ 最新的POI工具包

2 ． EXCEL 结构

HSSFWorkbook excell 文档对象介绍
HSSFSheet excell的表单
HSSFRow excell的行
HSSFCell excell的格子单元
HSSFFont excell字体
HSSFName 名称
HSSFDataFormat 日期格式
在poi1.7中才有以下2项：
HSSFHeader sheet头
HSSFFooter sheet尾
和这个样式
HSSFCellStyle cell样式
辅助操作包括
HSSFDateUtil 日期
HSSFPrintSetup 打印
HSSFErrorConstants 错误信息表

3 ．具体用法实例（采用 usermodel ）

如何读Excel

读取Excel文件时，首先生成一个POIFSFileSystem对象，由POIFSFileSystem对象构造一个HSSFWorkbook，该HSSFWorkbook对象就代表了Excel文档。下面代码读取上面生成的Excel文件写入的消息字串：

代码

POIFSFileSystem fs=newPOIFSFileSystem(new FileInputStream("d:\test.xls"));
HSSFWorkbook 　wb = new HSSFWorkbook(fs);
　　} catch (IOException e) {
　　e.printStackTrace();
　　}
　　HSSFSheet sheet = wb.getSheetAt(0);
　　HSSFRow row = sheet.getRow(0);
　　HSSFCell cell = row.getCell((short) 0);
　　String msg = cell.getStringCellValue();

如何写excel，

将excel的第一个表单第一行的第一个单元格的值写成“a test”。

代码

POIFSFileSystem fs =new POIFSFileSystem(new FileInputStream("workbook.xls"));
HSSFWorkbook wb = new HSSFWorkbook(fs);
HSSFSheet sheet = wb.getSheetAt(0);
HSSFRow row = sheet.getRow(0);
HSSFCell cell = row.getCell((short)0);
cell.setCellValue("a test");
// Write the output to a file
FileOutputStream fileOut = new FileOutputStream("workbook.xls");
wb.write(fileOut);
fileOut.close();

4 ．可参考文档

POI 主页：http://jakarta.apache.org/poi/，

初学者如何快速上手使用POI HSSF

http://jakarta.apache.org/poi/hssf/quick-guide.html 。

代码例子 http://blog.java-cn.com/user1/6749/archives/2005/18347.html

里面有很多例子代码，可以很方便上手。

四．使用心得

POI HSSF 的usermodel包把Excel文件映射成我们熟悉的结构，诸如Workbook、Sheet、Row、Cell等，它把整个结构以一组对象的形式保存在内存之中，便于理解，操作方便，基本上能够满足我们的要求，所以说这个一个不错的选择。

POI Excel整理(转)

liaojiyong — Wed, 14 Nov 2007 14:25:00 GMT

1.创建工作簿 (WORKBOOK)
    HSSFWorkbook wb = new HSSFWorkbook();
    FileOutputStream fileOut = new FileOutputStream("workbook.xls");
    wb.write(fileOut);
    fileOut.close();
2.创建工作表（SHEET）
    HSSFWorkbook wb = new HSSFWorkbook();
    HSSFSheet sheet1 = wb.createSheet("new sheet");
    HSSFSheet sheet2 = wb.createSheet("second sheet");
    FileOutputStream fileOut = new FileOutputStream("workbook.xls");
    wb.write(fileOut);
    fileOut.close();
3.创建单元格(CELL)
    HSSFWorkbook wb = new HSSFWorkbook();
    HSSFSheet sheet = wb.createSheet("new sheet");
    // Create a row and put some cells in it. Rows are 0 based.
    HSSFRow row = sheet.createRow((short)0);
    // Create a cell and put a value in it.
    HSSFCell cell = row.createCell((short)0);
    cell.setCellValue(1);
    // Or do it on one line.
    row.createCell((short)1).setCellValue(1.2);
    row.createCell((short)2).setCellValue("This is a string");
    row.createCell((short)3).setCellValue(true);
    // Write the output to a file
    FileOutputStream fileOut = new FileOutputStream("workbook.xls");
    wb.write(fileOut);
    fileOut.close();
4.创建指定单元格式的单元格
    HSSFWorkbook wb = new HSSFWorkbook();
    HSSFSheet sheet = wb.createSheet("new sheet");
    // Create a row and put some cells in it. Rows are 0 based.
    HSSFRow row = sheet.createRow((short)0);
    // Create a cell and put a date value in it. The first cell is not styled
    // as a date.
    HSSFCell cell = row.createCell((short)0);
    cell.setCellValue(new Date());
    // we style the second cell as a date (and time). It is important to
    // create a new cell style from the workbook otherwise you can end up
    // modifying the built in style and effecting not only this cell but other cells.
    HSSFCellStyle cellStyle = wb.createCellStyle();
    cellStyle.setDataFormat(HSSFDataFormat.getBuiltinFormat("m/d/yy h:mm"));
    cell = row.createCell((short)1);
    cell.setCellValue(new Date());
    cell.setCellStyle(cellStyle);
    // Write the output to a file
    FileOutputStream fileOut = new FileOutputStream("workbook.xls");
    wb.write(fileOut);
    fileOut.close();
5. 单元格的不同格式
    HSSFWorkbook wb = new HSSFWorkbook();
    HSSFSheet sheet = wb.createSheet("new sheet");
    HSSFRow row = sheet.createRow((short)2);
    row.createCell((short) 0).setCellValue(1.1);
    row.createCell((short) 1).setCellValue(new Date());
    row.createCell((short) 2).setCellValue("a string");
    row.createCell((short) 3).setCellValue(true);
    row.createCell((short) 4).setCellType(HSSFCell.CELL_TYPE_ERROR);
    // Write the output to a file
    FileOutputStream fileOut = new FileOutputStream("workbook.xls");
    wb.write(fileOut);
    fileOut.close();
6.单元格的不通对齐方式
    public static void main(String[] args)
            throws IOException
    {
        HSSFWorkbook wb = new HSSFWorkbook();
        HSSFSheet sheet = wb.createSheet("new sheet");
        HSSFRow row = sheet.createRow((short) 2);
        createCell(wb, row, (short) 0, HSSFCellStyle.ALIGN_CENTER);
        createCell(wb, row, (short) 1, HSSFCellStyle.ALIGN_CENTER_SELECTION);
        createCell(wb, row, (short) 2, HSSFCellStyle.ALIGN_FILL);
        createCell(wb, row, (short) 3, HSSFCellStyle.ALIGN_GENERAL);
        createCell(wb, row, (short) 4, HSSFCellStyle.ALIGN_JUSTIFY);
        createCell(wb, row, (short) 5, HSSFCellStyle.ALIGN_LEFT);
        createCell(wb, row, (short) 6, HSSFCellStyle.ALIGN_RIGHT);

        FileOutputStream fileOut = new FileOutputStream("workbook.xls");
        wb.write(fileOut);
        fileOut.close();
    }
    /**
     * Creates a cell and aligns it a certain way.
     *
     * @param wb        the workbook
     * @param row       the row to create the cell in
     * @param column    the column number to create the cell in
     * @param align     the alignment for the cell.
     */
    private static void createCell(HSSFWorkbook wb, HSSFRow row, short column, short align)
    {
        HSSFCell cell = row.createCell(column);
        cell.setCellValue("Align It");
        HSSFCellStyle cellStyle = wb.createCellStyle();
        cellStyle.setAlignment(align);
        cell.setCellStyle(cellStyle);
    }
7.单元格的边框设置
Working with borders
    HSSFWorkbook wb = new HSSFWorkbook();
    HSSFSheet sheet = wb.createSheet("new sheet");
    // Create a row and put some cells in it. Rows are 0 based.
    HSSFRow row = sheet.createRow((short) 1);
    // Create a cell and put a value in it.
    HSSFCell cell = row.createCell((short) 1);
    cell.setCellValue(4);
    // Style the cell with borders all around.
    HSSFCellStyle style = wb.createCellStyle();
    style.setBorderBottom(HSSFCellStyle.BORDER_THIN);
    style.setBottomBorderColor(HSSFColor.BLACK.index);
    style.setBorderLeft(HSSFCellStyle.BORDER_THIN);
    style.setLeftBorderColor(HSSFColor.GREEN.index);
    style.setBorderRight(HSSFCellStyle.BORDER_THIN);
    style.setRightBorderColor(HSSFColor.BLUE.index);
    style.setBorderTop(HSSFCellStyle.BORDER_MEDIUM_DASHED);
    style.setTopBorderColor(HSSFColor.BLACK.index);
    cell.setCellStyle(style);
    // Write the output to a file
    FileOutputStream fileOut = new FileOutputStream("workbook.xls");
    wb.write(fileOut);
    fileOut.close();
8.填充和颜色设置
    HSSFWorkbook wb = new HSSFWorkbook();
    HSSFSheet sheet = wb.createSheet("new sheet");
    // Create a row and put some cells in it. Rows are 0 based.
    HSSFRow row = sheet.createRow((short) 1);
    // Aqua background
    HSSFCellStyle style = wb.createCellStyle();
    style.setFillBackgroundColor(HSSFColor.AQUA.index);
    style.setFillPattern(HSSFCellStyle.BIG_SPOTS);
    HSSFCell cell = row.createCell((short) 1);
    cell.setCellValue("X");
    cell.setCellStyle(style);
    // Orange "foreground", foreground being the fill foreground not the font color.
    style = wb.createCellStyle();
    style.setFillForegroundColor(HSSFColor.ORANGE.index);
    style.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);
    cell = row.createCell((short) 2);
    cell.setCellValue("X");
    cell.setCellStyle(style);
    // Write the output to a file
    FileOutputStream fileOut = new FileOutputStream("workbook.xls");
    wb.write(fileOut);
    fileOut.close();
9.合并单元格操作
    HSSFWorkbook wb = new HSSFWorkbook();
    HSSFSheet sheet = wb.createSheet("new sheet");
    HSSFRow row = sheet.createRow((short) 1);
    HSSFCell cell = row.createCell((short) 1);
    cell.setCellValue("This is a test of merging");
    sheet.addMergedRegion(new Region(1,(short)1,1,(short)2));
    // Write the output to a file
    FileOutputStream fileOut = new FileOutputStream("workbook.xls");
    wb.write(fileOut);
    fileOut.close();
10.字体设置
    HSSFWorkbook wb = new HSSFWorkbook();
    HSSFSheet sheet = wb.createSheet("new sheet");
    // Create a row and put some cells in it. Rows are 0 based.
    HSSFRow row = sheet.createRow((short) 1);
    // Create a new font and alter it.
    HSSFFont font = wb.createFont();
    font.setFontHeightInPoints((short)24);
    font.setFontName("Courier New");
    font.setItalic(true);
    font.setStrikeout(true);
    // Fonts are set into a style so create a new one to use.
    HSSFCellStyle style = wb.createCellStyle();
    style.setFont(font);
    // Create a cell and put a value in it.
    HSSFCell cell = row.createCell((short) 1);
    cell.setCellValue("This is a test of fonts");
    cell.setCellStyle(style);
    // Write the output to a file
    FileOutputStream fileOut = new FileOutputStream("workbook.xls");
    wb.write(fileOut);
    fileOut.close();
11.自定义颜色
    HSSFWorkbook wb = new HSSFWorkbook();
    HSSFSheet sheet = wb.createSheet();
    HSSFRow row = sheet.createRow((short) 0);
    HSSFCell cell = row.createCell((short) 0);
    cell.setCellValue("Default Palette");
    //apply some colors from the standard palette,
    // as in the previous examples.
    //we'll use red text on a lime background
    HSSFCellStyle style = wb.createCellStyle();
    style.setFillForegroundColor(HSSFColor.LIME.index);
    style.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);
    HSSFFont font = wb.createFont();
    font.setColor(HSSFColor.RED.index);
    style.setFont(font);
    cell.setCellStyle(style);
    //save with the default palette
    FileOutputStream out = new FileOutputStream("default_palette.xls");
    wb.write(out);
    out.close();
    //now, let's replace RED and LIME in the palette
    // with a more attractive combination
    // (lovingly borrowed from freebsd.org)
    cell.setCellValue("Modified Palette");
    //creating a custom palette for the workbook
    HSSFPalette palette = wb.getCustomPalette();
    //replacing the standard red with freebsd.org red
    palette.setColorAtIndex(HSSFColor.RED.index,
            (byte) 153, //RGB red (0-255)
            (byte) 0,    //RGB green
            (byte) 0     //RGB blue
    );
    //replacing lime with freebsd.org gold
    palette.setColorAtIndex(HSSFColor.LIME.index, (byte) 255, (byte) 204, (byte) 102);
    //save with the modified palette
    // note that wherever we have previously used RED or LIME, the
    // new colors magically appear
    out = new FileOutputStream("modified_palette.xls");
    wb.write(out);
    out.close();
12.读和重写EXCEL文件
    POIFSFileSystem fs      =
            new POIFSFileSystem(new FileInputStream("workbook.xls"));
    HSSFWorkbook wb = new HSSFWorkbook(fs);
    HSSFSheet sheet = wb.getSheetAt(0);
    HSSFRow row = sheet.getRow(2);
    HSSFCell cell = row.getCell((short)3);
    if (cell == null)
        cell = row.createCell((short)3);
    cell.setCellType(HSSFCell.CELL_TYPE_STRING);
    cell.setCellValue("a test");
    // Write the output to a file
    FileOutputStream fileOut = new FileOutputStream("workbook.xls");
    wb.write(fileOut);
    fileOut.close();
13.在EXCEL单元格中使用自动换行
    HSSFWorkbook wb = new HSSFWorkbook();
    HSSFSheet s = wb.createSheet();
    HSSFRow r = null;
    HSSFCell c = null;
    HSSFCellStyle cs = wb.createCellStyle();
    HSSFFont f = wb.createFont();
    HSSFFont f2 = wb.createFont();
    cs = wb.createCellStyle();
    cs.setFont( f2 );
    //Word Wrap MUST be turned on
    cs.setWrapText( true );
    r = s.createRow( (short) 2 );
    r.setHeight( (short) 0x349 );
    c = r.createCell( (short) 2 );
    c.setCellType( HSSFCell.CELL_TYPE_STRING );
    c.setCellValue( "Use \n with word wrap on to create a new line" );
    c.setCellStyle( cs );
    s.setColumnWidth( (short) 2, (short) ( ( 50 * 8 ) / ( (double) 1 / 20 ) ) );
    FileOutputStream fileOut = new FileOutputStream( "workbook.xls" );
    wb.write( fileOut );
    fileOut.close();
14.数字格式自定义
    HSSFWorkbook wb = new HSSFWorkbook();
    HSSFSheet sheet = wb.createSheet("format sheet");
    HSSFCellStyle style;
    HSSFDataFormat format = wb.createDataFormat();
    HSSFRow row;
    HSSFCell cell;
    short rowNum = 0;
    short colNum = 0;
    row = sheet.createRow(rowNum++);
    cell = row.createCell(colNum);
    cell.setCellValue(11111.25);
    style = wb.createCellStyle();
    style.setDataFormat(format.getFormat("0.0"));
    cell.setCellStyle(style);
    row = sheet.createRow(rowNum++);
    cell = row.createCell(colNum);
    cell.setCellValue(11111.25);
    style = wb.createCellStyle();
    style.setDataFormat(format.getFormat("#,##0.0000"));
    cell.setCellStyle(style);
    FileOutputStream fileOut = new FileOutputStream("workbook.xls");
    wb.write(fileOut);
    fileOut.close();
15.调整工作单位置
    HSSFWorkbook wb = new HSSFWorkbook();
    HSSFSheet sheet = wb.createSheet("format sheet");
    HSSFPrintSetup ps = sheet.getPrintSetup();
    sheet.setAutobreaks(true);
    ps.setFitHeight((short)1);
    ps.setFitWidth((short)1);

    // Create various cells and rows for spreadsheet.
    FileOutputStream fileOut = new FileOutputStream("workbook.xls");
    wb.write(fileOut);
    fileOut.close();
16.设置打印区域
    HSSFWorkbook wb = new HSSFWorkbook();
    HSSFSheet sheet = wb.createSheet("Sheet1");
    wb.setPrintArea(0, "$A$1:$C$2");
    //sets the print area for the first sheet
    //Alternatively:
    //wb.setPrintArea(0, 0, 1, 0, 0) is equivalent to using the name reference (See the JavaDocs for more details)
    // Create various cells and rows for spreadsheet.
    FileOutputStream fileOut = new FileOutputStream("workbook.xls");
    wb.write(fileOut);
    fileOut.close();
17.标注脚注
    HSSFWorkbook wb = new HSSFWorkbook();
    HSSFSheet sheet = wb.createSheet("format sheet");
    HSSFFooter footer = sheet.getFooter()
    footer.setRight( "Page " + HSSFFooter.page() + " of " + HSSFFooter.numPages() );

    // Create various cells and rows for spreadsheet.
    FileOutputStream fileOut = new FileOutputStream("workbook.xls");
    wb.write(fileOut);
    fileOut.close();
18.使用方便的内部提供的函数
    HSSFWorkbook wb = new HSSFWorkbook();
    HSSFSheet sheet1 = wb.createSheet( "new sheet" );
    // Create a merged region
    HSSFRow row = sheet1.createRow( (short) 1 );
    HSSFRow row2 = sheet1.createRow( (short) 2 );
    HSSFCell cell = row.createCell( (short) 1 );
    cell.setCellValue( "This is a test of merging" );
    Region region = new Region( 1, (short) 1, 4, (short) 4 );
    sheet1.addMergedRegion( region );
    // Set the border and border colors.
    final short borderMediumDashed = HSSFCellStyle.BORDER_MEDIUM_DASHED;
    HSSFRegionUtil.setBorderBottom( borderMediumDashed,
        region, sheet1, wb );
    HSSFRegionUtil.setBorderTop( borderMediumDashed,
        region, sheet1, wb );
    HSSFRegionUtil.setBorderLeft( borderMediumDashed,
        region, sheet1, wb );
    HSSFRegionUtil.setBorderRight( borderMediumDashed,
        region, sheet1, wb );
    HSSFRegionUtil.setBottomBorderColor(HSSFColor.AQUA.index, region, sheet1, wb);
    HSSFRegionUtil.setTopBorderColor(HSSFColor.AQUA.index, region, sheet1, wb);
    HSSFRegionUtil.setLeftBorderColor(HSSFColor.AQUA.index, region, sheet1, wb);
    HSSFRegionUtil.setRightBorderColor(HSSFColor.AQUA.index, region, sheet1, wb);
    // Shows some usages of HSSFCellUtil
    HSSFCellStyle style = wb.createCellStyle();
    style.setIndention((short)4);
    HSSFCellUtil.createCell(row, 8, "This is the value of the cell", style);
    HSSFCell cell2 = HSSFCellUtil.createCell( row2, 8, "This is the value of the cell");
    HSSFCellUtil.setAlignment(cell2, wb, HSSFCellStyle.ALIGN_CENTER);
    // Write out the workbook
    FileOutputStream fileOut = new FileOutputStream( "workbook.xls" );
    wb.write( fileOut );
    fileOut.close();
19.在工作单中移动行，调整行的上下位置
    HSSFWorkbook wb = new HSSFWorkbook();
    HSSFSheet sheet = wb.createSheet("row sheet");
    // Create various cells and rows for spreadsheet.
    // Shift rows 6 - 11 on the spreadsheet to the top (rows 0 - 5)
    sheet.shiftRows(5, 10, -5);
    FileOutputStream fileOut = new FileOutputStream("workbook.xls");
    wb.write(fileOut);
    fileOut.close();
20.选种指定的工作单
    HSSFWorkbook wb = new HSSFWorkbook();
    HSSFSheet sheet = wb.createSheet("row sheet");
    sheet.setSelected(true);
    // Create various cells and rows for spreadsheet.
    FileOutputStream fileOut = new FileOutputStream("workbook.xls");
    wb.write(fileOut);
    fileOut.close();
21.工作单的放大缩小
    HSSFWorkbook wb = new HSSFWorkbook();
    HSSFSheet sheet1 = wb.createSheet("new sheet");
    sheet1.setZoom(3,4);   // 75 percent magnification
    FileOutputStream fileOut = new FileOutputStream("workbook.xls");
    wb.write(fileOut);
    fileOut.close();
22.头注和脚注
    HSSFWorkbook wb = new HSSFWorkbook();
    HSSFSheet sheet = wb.createSheet("new sheet");
    HSSFHeader header = sheet.getHeader();
    header.setCenter("Center Header");
    header.setLeft("Left Header");
    header.setRight(HSSFHeader.font("Stencil-Normal", "Italic") +
                    HSSFHeader.fontSize((short) 16) + "Right w/ Stencil-Normal Italic font and size 16");
    FileOutputStream fileOut = new FileOutputStream("workbook.xls");
    wb.write(fileOut);
    fileOut.close();

    * 自定义颜色，去掉注释，贴加，其他则查看颜色对照表
   HSSFPalette palette = this.getCustomPalette();
   palette.setColorAtIndex(idx,
