验证单元格¶
数据验证器可以应用于范围单元格，但也不是强制和 evaluated。范围不必是连续的：例如 “A1 B2:B5” 包含 A1 和单元格 B2 至 B5，但不包含 A2 或 B2。
例子¶
>>> from openpyxl import Workbook
>>> from openpyxl.worksheet.datavalidation import DataValidation
>>>
>>> # Create the workbook and worksheet we'll be working with
>>> wb = Workbook()
>>> ws = wb.active
>>>
>>> # Create a data-validation object with list validation
>>> dv = DataValidation(type="list", formula1='"Dog,Cat,Bat"', allow_blank=True)
>>>
>>> # Optionally set a custom error message
>>> dv.error ='Your entry is not in the list'
>>> dv.errorTitle = 'Invalid Entry'
>>>
>>> # Optionally set a custom prompt message
>>> dv.prompt = 'Please select from the list'
>>> dv.promptTitle = 'List Selection'
>>>
>>> # Add the data-validation object to the worksheet
>>> ws.add_data_validation(dv)
>>> # Create some cells, and add them to the data-validation object
>>> c1 = ws["A1"]
>>> c1.value = "Dog"
>>> dv.add(c1)
>>> c2 = ws["A2"]
>>> c2.value = "An invalid value"
>>> dv.add(c2)
>>>
>>> # Or, apply the validation to a range of cells
>>> dv.add('B1:B1048576') # This is the same as for the whole of column B
>>>
>>> # Check with a cell is in the validator
>>> "B4" in dv
True
备注
没有在任何单元格应用的验证将会在保存的时候被忽略。
其他验证的例子¶
任何：
dv = DataValidation(type="whole")
任何大于 100 的整数：
dv = DataValidation(type="whole",
operator="greaterThan",
formula1=100)
任何小数：
dv = DataValidation(type="decimal")
任何在0至1之间的小数：
dv = DataValidation(type="decimal",
operator="between",
formula1=0,
formula2=1)
任何日期：
dv = DataValidation(type="date")
或 时间：
dv = DataValidation(type="time")
15 字符以下的字符串：
dv = DataValidation(type="textLength",
operator="lessThanOrEqual"),
formula1=15)
单元格区域验证：
from openpyxl.utils import quote_sheetname
dv = DataValidation(type="list",
formula1="{0}!$B$1:$B$10".format(quote_sheetname(sheetname))
)
自定义规则：
dv = DataValidation(type="custom",
formula1"=SOMEFORMULA")
