格式化字體和對齊

Question

我正在嘗試使用Python 2.7和OpenPyXL 2.4.5將字體和對齊添加到Excel工作表。我收到以下錯誤，但我不明白爲什麼。任何人都可以向我解釋這個嗎？從我的測試中，它與我設置字體有關（錯誤？），而不是實際保存。

    raise TypeError('expected ' + str(expected_type)) 
TypeError: expected <class 'openpyxl.styles.fonts.Font'> 

這是我的代碼。

    report_wb.save(report_fname) 
if __name__ == "__main__": 
    main() 

奇怪的是，我當我試圖改變字體和排列以下方式沒有得到錯誤。但是，我希望能夠使用類似於上面的內容來避免在格式化時通過整個數據集進行循環。

Answer 1

我認爲問題在於您將單元格的font屬性設置爲對齊對象。

在你的代碼的這一部分，你有這個。在本節中，您有最後一行

if x_axis == 1: 
    if ws_to_format.cell(row=1, column=y_axis).value: 
     ws_to_format.cell(row=1, column=y_axis).font = header_font 
     ws_to_format.cell(row=1, column=y_axis).font = header_alignment 

公告..... 字體 = header_ 對準

嘗試改變，要對齊，看看它是否適合你

if x_axis == 1: 
    if ws_to_format.cell(row=1, column=y_axis).value: 
     ws_to_format.cell(row=1, column=y_axis).font = header_font 
     ws_to_format.cell(row=1, column=y_axis).alignment = header_alignment
