我收到此错误：ImportError: No module named style，来自此导入语句：from openpyxl.style import Style
以下是与数据透视表相关的代码：
excel = pd.ExcelFile(filename)
df = excel.parse(sheetname=0)
df1 = df[['Product Description', 'Supervisor']]
print df1
table1 = pd.pivot_table(df1, rows = ['Supervisor'],
cols = ['Product Description'],
values = ['Product Description'],
aggfunc = [lambda x: len(x)], fill_value = 0)
writer = pd.ExcelWriter(filename)
table1.to_excel(writer, 'Pivot Table')
writer.save()
workbook.save(filename)
我唯一可以想到的可能是它会导致Supervisor列的标题应用了一个样式（这只是对单词＆＃39; Supervisor＆＃39;应用粗体样式）。删除应用样式的行并不能解决问题。
supervisorheader = worksheet.cell("CV1")
s = Style(font=Font(bold=True))
supervisorheader.style = s
以下是我的数据框：
