1.创建工作薄,sheet页

Workbook workBook = new XSSFWorkbook();Sheet sheet = workBook.createSheet("test");

2.设置单个单元格内容

Row row = sheet.createRow(0);row.createCell(0).setCellValue("C");

3.限制此单元格只支持特定内容,如输入其它内容,直接提示错误信息。

String []values = {"A","B","C","D"};XSSFDataValidationConstraint constraint = new XSSFDataValidationConstraint(values);CellRangeAddressList regions = new CellRangeAddressList(0,0,0,0);DataValidationHelper help = new    XSSFDataValidationHelper((XSSFSheet)sheet);DataValidation validation = help.createValidation(constraint, regions);validation.createErrorBox("输入值有误", "请从下拉框中选择");validation.setShowErrorBox(true);sheet.addValidationData(validation);

4.对单元格只能输入数字类型进行限制。

row.createCell(1).setCellValue(3);row.createCell(1).setCellType(Cell.CELL_TYPE_NUMERIC)DataValidationConstraint constrain = new XSSFDataValidationConstraint(DataValidationConstraint.ValidationType.INTEGER,DataValidationConstraint.OperatorType.BETWEEN,"1","10");CellRangeAddressList region = new CellRangeAddressList(0,0,1,1);DataValidation vali = help.createValidation(constrain, region);vali.createErrorBox("输入值类型或大小有误", "数值型,请输入1~10之间的数值");validation.setShowErrorBox(true);sheet.addValidationData(vali);

5.把文件保存到特定文件路径下。

try {   workBook.write(new FileOutputStream("F:/zjc.xlsx"));} catch (FileNotFoundException e) {   e.printStackTrace();

} catch (IOException e) {   e.printStackTrace();}

右键设置单元格式,分类"数值",设置"使用千分位分隔符"

回答(3):

Range("E5").Select
Selection.NumberFormatLocal = _
"_ ¥* #,##0.00_ ;_ ¥* -#,##0.00_ ;_ ¥* ""-""??_ ;_ @_ "

回答(4):

Sub aa()

Cells.Select
Selection.NumberFormatLocal = _
"_ * #,##0.00_ ;_ * -#,##0.00_ ;_ * ""-""??_ ;_ @_ "
End Sub

查一下poi的API,应该是可以设置相关属性的
