1、如何创建一个新的Workbook
Workbook wb = new HSSFWorkbook();
FileOutputStream fileOut = new FileOutputStream(\ wb.write(fileOut); fileOut.close();
Workbook wb = new XSSFWorkbook();
FileOutputStream fileOut = new FileOutputStream(\ wb.write(fileOut); fileOut.close();
2、如何创建一个表
Workbook wb = new HSSFWorkbook(); //or new XSSFWorkbook(); Sheet sheet1 = wb.createSheet(\ Sheet sheet2 = wb.createSheet(\ //注意Excel工作表名称不得超过31个字符 //并且不能包含以下任何字符:
//0x0000、0x0003、冒号(:)、反斜杠(\\)、星号(*)、问号(？)、正斜杠(/)、[、]
//可以使用org.apache.poi.ss.util.WorkbookUtil＃createSafeSheetName(String nameProposal)}
//为了安全地创建有效名称,此实用程序用空格('')替换无效字符
String safeName = WorkbookUtil.createSafeSheetName(\sales*?]\//returns \O'Brien's sales \
Sheet sheet3 = wb.createSheet(safeName);
FileOutputStream fileOut = new FileOutputStream(\ wb.write(fileOut); fileOut.close();
3、如何创建单元格
Workbook wb = new HSSFWorkbook(); //Workbook wb = new XSSFWorkbook();
CreationHelper createHelper = wb.getCreationHelper(); Sheet sheet = wb.createSheet(\
//创建一个行并在其中放置一些单元格。行号从0开始。 Row row = sheet.createRow((short)0);
//创建一个单元格并在其中放入一个值。 Cell cell = row.createCell(0); cell.setCellValue(1);
//或在一行上。
row.createCell(1).setCellValue(1.2); row.createCell(2).setCellValue(
createHelper.createRichTextString(\ row.createCell(3).setCellValue(true);
//将输出写入文件
FileOutputStream fileOut = new FileOutputStream(\ wb.write(fileOut); fileOut.close();
4、如何创建日期单元格
Workbook wb = new HSSFWorkbook(); //Workbook wb = new XSSFWorkbook();
CreationHelper createHelper = wb.getCreationHelper(); Sheet sheet = wb.createSheet(\
//创建一个行并在其中放置一些单元格。行为0 Row row = sheet.createRow(0);
//创建一个单元格并在其中放置一个日期值。第一个单元格没有样式 //作为日期
Cell cell = row.createCell(0); cell.setCellValue(new Date());
//我们将第二个单元格设置为日期(和时间)。重要的是 //从Workbook 创建一个新的单元格样式,否则你可以结束 //修改内置样式,不仅影响这个单元格,而且影响其他单元格。 CellStyle cellStyle = wb.createCellStyle(); cellStyle.setDataFormat(
createHelper.createDataFormat().getFormat(\ cell = row.createCell(1);
cell.setCellValue(new Date()); cell.setCellStyle(cellStyle);
