使用 openpyxl 进行数据验证不会写入文件 - 包含代码

Question

实际写入每个文件的代码运行得很好。我遇到的问题是数据验证部分似乎没有做任何事情。在我引用的范围内没有创建下拉菜单。

预先感谢您的任何和所有帮助！

%%time

import pandas as pd
import xlsxwriter as ew
import csv as csv
import os
import glob
import openpyxl

#remove existing files from directory
files = glob.glob(#filename)
for f in files:
    os.remove(f)

pendpath = #filename
df = pd.read_sas(pendpath)

allusers = df.UserID_NB.unique()
listuserpath = #filename
listusers = pd.read_csv(listuserpath)

listusers = listusers['USER_ID'].apply(lambda x: str(x).strip())

for id in listusers:
    x = df.loc[df['UserID_NB']==id]
    path = #filename
    x.to_excel(path, sheet_name = str(id), index = False)

    from openpyxl import load_workbook

    wb = openpyxl.load_workbook(filename = path)
    sheet = wb.get_sheet_by_name(str(id))
    maxrow = sheet.max_row    

    from openpyxl.worksheet.datavalidation import DataValidation

    dv = DataValidation(type="list", formula1='"Yes,No"', allow_blank=False, showDropDown = True)
    rangevar = 'R1:T'+ str(maxrow)
    dv.ranges.append(rangevar)
    wb.save(path)
    print str(id), rangevar

基本表代码

 import openpyxl 

 wb = openpyxl.Workbook()
 ws = wb.active
 sheet.title = 'testsheet'

path = '#filepath'
from openpyxl.worksheet.datavalidation import DataValidation

dv = DataValidation(type="list", formula1='"Yes,No"', allow_blank=False, showDropDown = True)
dv.ranges.append('A1')
wb.save(path)

Answer 1

您缺少添加dv到worksheet.

>>> # Add the data-validation object to the worksheet
>>> ws.add_data_validation(dv)
