[转]Hssfworkbook 设置单元格格式 setdataformat
HSSFWorkbook demoWorkBook = new HSSFWorkbook();
HSSFSheet demoSheet = demoWorkBook.createSheet("The World's 500 Enterprises");
HSSFCell cell = demoSheet.createRow(0).createCell(0);
1.设置单元格为文本格式
HSSFCellStyle cellStyle2 = demoWorkBook.createCellStyle();
HSSFDataFormat format = demoWorkBook.createDataFormat();
cellStyle2.setDataFormat(format.getFormat("@"));
cell.setCellStyle(cellStyle2);
第一种：日期格式
cell.setCellValue(new Date(2008,5,5));
//set date format
HSSFCellStyle cellStyle = demoWorkBook.createCellStyle();
HSSFDataFormat format= demoWorkBook.createDataFormat();
cellStyle.setDataFormat(format.getFormat("yyyy年m月d日"));
cell.setCellStyle(cellStyle);
第二种：保留两位小数格式
cell.setCellValue(1.2);
HSSFCellStyle cellStyle = demoWorkBook.createCellStyle();
cellStyle.setDataFormat(HSSFDataFormat.getBuiltinFormat("0.00"));
cell.setCellStyle(cellStyle);
第三种：货币格式
cell.setCellValue(20000);
HSSFCellStyle cellStyle = demoWorkBook.createCellStyle();
HSSFDataFormat format= demoWorkBook.createDataFormat();
cellStyle.setDataFormat(format.getFormat("¥#,##0"));
cell.setCellStyle(cellStyle);
第四种：百分比格式
cell.setCellValue(20);
HSSFCellStyle cellStyle = demoWorkBook.createCellStyle();
cellStyle.setDataFormat(HSSFDataFormat.getBuiltinFormat("0.00%"));
cell.setCellStyle(cellStyle);
此种情况跟第二种一样
第五种：中文大写格式
cell.setCellValue(20000);
HSSFCellStyle cellStyle = demoWorkBook.createCellStyle();
HSSFDataFormat format= demoWorkBook.createDataFormat();
cellStyle.setDataFormat(format.getFormat("[DbNum2][$-804]0"));
cell.setCellStyle(cellStyle);
第六种：科学计数法格式
cell.setCellValue(20000);
HSSFCellStyle cellStyle = demoWorkBook.createCellStyle();
cellStyle.setDataFormat( HSSFDataFormat.getBuiltinFormat("0.00E+00"));
cell.setCellStyle(cellStyle);
