在OpenPyxl中更改一行或一列的样式

我已经从NamedStyle切换为常规样式，这似乎对我来说更好。现在，我只是想尝试填充一行和一列-我有一些过度设计的位有效，但我很好奇为什么colA位不行。给我一个AtrributeError。

import openpyxl
from openpyxl.utils import get_column_letter
from openpyxl.styles import PatternFill, Border, Side, Alignment

wb = openpyxl.load_workbook('example5.xlsx')
sheet = wb['Sheet1']

day = ''
week = ('MONDAY', 'TUESDAY', 'WEDNESDAY', 'THURSDAY',
        'FRIDAY', 'SATURDAY', 'SUNDAY')

sheet['A2'] = 'Monday'
sheet['A3'] = 'Tuesday'
sheet['A4'] = 'Wednesday'
sheet['A5'] = 'Thursday'
sheet['A6'] = 'Friday'
sheet['A7'] = 'Saturday'
sheet['A8'] = 'Sunday'

sheet['A1'] = 'Day'
sheet['B1'] = 'In'
sheet['C1'] = 'Out'
sheet['D1'] = 'Total Hours'
sheet['E1'] = 'ST Hours'
sheet['F1'] = 'OT Hours'
sheet['G1'] = 'ST Rate'
sheet['H1'] = 'OT Rate'


while day not in week:
    day = input('What day of the week is it? ')
    day = day.upper()


def sheetStyle(var):
    sheet['B' + var].number_format = 'H:MM AM/PM'
    sheet['F' + var].number_format = 'H:MM AM/PM'
    sheet['C' + var].number_format = 'H:MM AM/PM'
    sheet['E' + var].number_format = 'General'
    sheet['F' + var].number_format = '#,##0.00'
    sheet['G' + var].number_format = '[$$]#,##0.00'
    sheet['H' + var].number_format = '[$$]#,##0.00'
    sheet['B' + var] = input('Enter the time you clocked in: ')
    sheet['C' + var] = input('Enter the time you clocked out: ')
    sheet['D' + var] = '=MOD(C' + var + '-B' + var + ',1)*24'
    sheet['E' + var] = '=D' + var + '-F' + var
    sheet['F' + var] = '=MAX(D' + var + '-8,0)'
    sheet['G' + var] = '=E' + var + '*15'
    sheet['H' + var] = '=F' + var + '*22.5'


def sheetInput(day=''):
    for i, w in enumerate(week):
        if day == w:
            sheetStyle(str(i + 2))


grayFill = PatternFill(start_color='D0CECE', end_color='D0CECE',
                       fill_type='solid')
whiteFill = PatternFill(start_color='FFFFFF', end_color='FFFFFF',
                        fill_type='solid')

for columns in sheet.iter_cols(min_col=None, max_col=None,
                               min_row=None, max_row=None):
    for cell in columns:
        cell.fill = grayFill

# for row in sheet.iter_rows(min_row=None, max_col=1, max_row=8):
#    for cell in row:
#        cell.fill = whiteFill

# for cell in sheet[1:1]:
#    cell.fill = whiteFill

colA = sheet['A']
colA.fill = whiteFill

column = 1
while column < 9:
    col = get_column_letter(column)
    sheet.column_dimensions[col].width = 20
    column += 1

for d in week:
    if d == day:
        sheetInput(day)

wb.save('example5.xlsx')

这是错误：
