xlwt.Style.EasyXFCallerError: section 'fill' is unknown

Question

我有一个数据框，我在其中进行更新，例如写入特定单元格并将背景色添加到特定单元格。在 dataframe 中看起来不错。但是当我将dataframe转换为excel时，发现下面的错误。

df.to_excel("test_sheet.xls") 导致错误。

Traceback (most recent call last):
  File "scoring_model.py", line 441, in <module>
    pf = ScoringModel()
  File "scoring_model.py", line 12, in __init__

    df.to_excel("test_sheet.xls")

    raise EasyXFCallerError('section %r is unknown' % section)
xlwt.Style.EasyXFCallerError: section 'fill' is unknown

使用最新的 python3.5 和 xlwt 1.3。有没有人发现同样的错误？

谢谢

Answer 1

你能粘贴到 xlwt_stylestr 吗？

那里可能有错字 [缺少 space 字符？]，因为我检查了异常的来源 - https://github.com/python-excel/xlwt/blob/master/xlwt/Style.py#L639

根据评论，你可以试试：

xlwt_stylestr = 'pattern: pattern solid, fore_colour red;'

然后将其传递给 write 可调用对象： https://xlwt.readthedocs.io/en/latest/api.html#xlwt.Worksheet.Worksheet.write styled.to_excel('styled.xlsx')

你能试试这个吗:

def bg_red(val):
    # this will receive each value in the excel
    # so if you want to add conditional logic, you can
    # add here
    return 'background-color: red'

style_obj  = df.style.applymap(bg_red)
style_obj.to_excel('styled_doc.xlsx')

虽然听起来很蹩脚，但我遇到了同样的困难，当我改变时停止了

df.to_excel("test_sheet.xls")

至

df.to_excel("test_sheet.xlsx")

FWIW 我也在使用 'xlsxwriter'

xlwt.Style.EasyXFCallerError: section 'fill' is unknown

xlwt.Style.EasyXFCallerError: section 'fill' is unknown

python

excel

xlwt

python-3.x

pandas
