工作薄中不同类型的单元格
[java]
Workbook wb = new HSSFWorkbook();
Sheet sheet = wb.createSheet("new sheet");
Row row = sheet.createRow(2);
row.createCell(0).setCellValue(1.1);//浮点
row.createCell(1).setCellValue(new Date());//日期
row.createCell(2).setCellValue(Calendar.getInstance());//日期
row.createCell(3).setCellValue("a string");//字符串
row.createCell(4).setCellValue(true);//Boolean
row.createCell(5).setCellType(Cell.CELL_TYPE_ERROR);//错误
// 写入文件
FileOutputStream fileOut = new FileOutputStream("workbook.xls");
wb.write(fileOut);
fileOut.close();
Workbook wb = new HSSFWorkbook();
Sheet sheet = wb.createSheet("new sheet");
Row row = sheet.createRow(2);
row.createCell(0).setCellValue(1.1);//浮点
row.createCell(1).setCellValue(new Date());//日期
row.createCell(2).setCellValue(Calendar.getInstance());//日期
row.createCell(3).setCellValue("a string");//字符串
row.createCell(4).setCellValue(true);//Boolean
row.createCell(5).setCellType(Cell.CELL_TYPE_ERROR);//错误
// 写入文件
FileOutputStream fileOut = new FileOutputStream("workbook.xls");
wb.write(fileOut);
fileOut.close();
