Question

我似乎无法解决这个问题：

我想访问给定列中的最后一个单元格，以便为其添加值。但我的代码不起作用：

from tkinter import *
import datetime
import openpyxl 
import os


wb = openpyxl.load_workbook("TimeSheet.xlsx", use_iterators=True)
ws1 = wb.get_sheet_by_name("TimeSheet")



master = Tk()

firstDate = Entry(master)
firstDate.pack()

firstDate.focus_set()


def date_receiving():

    totalRows = 0
    receivingDate = firstDate.get()
    for rowNum in ws1.iter_rows("B6:B"+str(ws1.max_row)):
        for cell in rowNum:
            print(cell)
        cellule = ws1.cell(row=rowNum, column=2).value
        if cellule != "":
            totalRows += 1
            print(totalRows)
        else:
            break

我尝试了一些事情，却无法找到最后一个空单元格。请帮忙！

谢谢，

以下是一些代码，可以将最后一个空单元格的编号作为maxBlank。让我知道它对你有用。

from Tkinter import *
import datetime
import openpyxl 
import os


wb = openpyxl.load_workbook("TimeSheet.xlsx", use_iterators=True)
ws1 = wb.get_sheet_by_name("TimeSheet")



master = Tk()

firstDate = Entry(master)
firstDate.pack()

firstDate.focus_set()


def date_receiving():

    maxBlank = -1
    for rowNum in ws1.iter_rows("B6:B"+str(ws1.max_row)):
        for cell in rowNum:
            if cell.internal_value == None:
                if cell.row > maxBlank:
                    maxBlank =  cell.row
    print maxBlank

openpyxl - 编辑行的最后一个值
