我正在尝试将数据导出到应用了条件格式的excel文件中：

import pandas as pd
from openpyxl import Workbook
from openpyxl.styles import Color, PatternFill, Font, Border
from openpyxl.styles.differential import DifferentialStyle
from openpyxl.formatting.rule import ColorScaleRule, CellIsRule, FormulaRule

df = pd.DataFrame({'Data': [10, 20, 30, 20, 15, 30, 45]})
writer = pd.ExcelWriter('pandas_simple.xlsx', engine='xlsxwriter')
df.to_excel(writer, sheet_name='Sheet1')
wb  = writer.book
ws = writer.sheets['Sheet1']

ws.conditional_formatting.add('A1:A10',
                          ColorScaleRule(start_type='min', start_color='AA0000',
                                         end_type='max', end_color='00AA00')
                         )

worksheet.conditional_formatting.add("O2:O295", color_scale_rule)
workbook.save(filename="sample_conditional_formatting_color_scale.xlsx")

我收到以下错误：

AttributeError: 'Worksheet' object has no attribute 'conditional_formatting'

我的目标是：

python openpyxl

您创建的Dataframe不正确。

import pandas as pd
import openpyxl
from openpyxl import Workbook
from openpyxl.styles import Color, PatternFill, Font, Border
from openpyxl.styles.differential import DifferentialStyle
from openpyxl.formatting.rule import ColorScaleRule, CellIsRule, FormulaRule

df = pd.DataFrame({'Data': [10, 20, 30, 20, 15, 30, 45]})
path = 'pandas_simple.xlsx'
df.to_excel(path, sheet_name='Sheet1', index=False)
wb  = openpyxl.load_workbook(path)
ws = wb['Sheet1']

# Add a three-color scale

ws.conditional_formatting.add('A1:A10',
                ColorScaleRule(start_type='percentile', start_value=10, start_color='AA0000',
                            mid_type='percentile', mid_value=50, mid_color='0000AA',
                            end_type='percentile', end_value=90, end_color='00AA00')
                              )

wb.save(filename="sample_conditional_formatting_color_scale.xlsx")

输出：

调整色阶以匹配预期输出是留给读者的练习。
