有没有办法通过Python触发excel文档中的格式设置

我正在编写一个自动excel工作表比较python脚本，但在打开excel文档时，我很难显示所做的更改。基本上，它会进行单元格级别的比较，如果单元格发生变化，则添加红色填充，如果单元格未发生变化，则添加绿色填充。我正在使用openpyxl编辑值，并更改填充颜色。代码运行后，我打开excel文件看不到任何更改。但是，当我单击单元格本身时，我可以看到颜色填充的变化。我需要帮助找到一个解决方案，该解决方案将在我打开excel文件之前自动触发该格式显示。有人有这方面的经验吗

要运行，请创建一个名为“test”的excel文件，然后将值添加到Sheet1第一列的行中。创建第二张图纸2，并为第一列的一半添加相同的值，然后更改第一列的另一半的值。保存、关闭文件、运行。然后寻找变化

import pandas as pd 
import openpyxl as op
from openpyxl.utils.cell import get_column_letter
from openpyxl.styles import PatternFill

def main():
    old_tab = "Sheet1"
    new_tab = "Sheet2"

    # set up A1:A10 on Sheet1 all to be = 10
    # ... then on Sheet2, have A1:A5 be = 10, and A6:A10 be = 20
    path = './test.xlsx'

    # set up list to track indices that should be highlighted red
    cells_to_highlight_red = []
    red_fill = PatternFill(fill_type=None, start_color='FFFFFFFF', end_color='FF0000')

    # set up list to track indices that should be highlighted green
    cells_to_highlight_green = []
    green_fill = PatternFill(fill_type=None, start_color='FFFFFFFF', end_color='008000')

    old_sheet = pd.read_excel(path,  sheet_name=old_tab, data_only=True, header=None).fillna('-')
    new_sheet = pd.read_excel(path,  sheet_name=new_tab, data_only=True, header=None).fillna('-')

    # do cell by cell comparison to see if cells have changed
    bool_df = old_sheet.eq(new_sheet)

    # go through each column
    for col_index in range(bool_df.shape[1]):
        # then through each row of the bool_df. 
        # ... if the cell is False, that means a change has occurred
        # ... if the cell is not False, so True, that means no 
        for row_index, row in enumerate(bool_df.iloc[:,col_index].values.flatten()):
            if row == False:
                col_letter = get_column_letter(col_index+1)
                trg_cell = col_letter + str(row_index+1)
                trg_cell.replace(" ", "")
                # if this is true, then there was no value to begin or end, so do not add to list to track
                if old_sheet.iloc[row_index, col_index] == "-" and new_sheet.iloc[row_index, col_index] == "-":
                    continue
                cells_to_highlight_red.append(trg_cell)
            else:
                col_letter = get_column_letter(col_index+1)
                trg_cell = col_letter + str(row_index+1)
                trg_cell.replace(" ", "")
                # if this is true, then there was no value to begin or end, so do not add to list to track
                if old_sheet.iloc[row_index, col_index] == "-" and new_sheet.iloc[row_index, col_index] == "-":
                    continue
                cells_to_highlight_green.append(trg_cell)

    target_workbook = op.load_workbook( filename=path )
    target_sheet = target_workbook["Sheet2"]

    for trg_col_row in cells_to_highlight_red:
        cell_to_edit = target_sheet[trg_col_row]
        cell_to_edit.fill = red_fill

    for trg_col_row in cells_to_highlight_green:
        cell_to_edit = target_sheet[trg_col_row]
        cell_to_edit.fill = green_fill

    target_workbook.save( path )


main()
