格式化字体和对齐

Question

我正在尝试使用 Python 2.7 和 OpenPyXL 2.4.5 向 Excel 工作表添加字体和对齐方式。我收到以下错误，但我不明白为什么。谁能给我解释一下？根据我的测试，这与我设置字体有关（不正确？），而不是实际保存。

C:\Scripts\Stack_Overflow>xlsx_font_and_alignment.py

    raise TypeError('expected ' + str(expected_type))

这是我的代码。

奇怪的是，当我尝试按以下方式更改字体和对齐方式时，我没有收到错误消息。但是，我希望能够使用与上述类似的方法来避免在格式化时遍历整个数据集。

                ws_to_format.cell(row=x_axis, column=y_axis).alignment = report_alignment
    for y_axis in range(1, column_count+1):
        ws_to_format.cell(row=1, column=y_axis).font = header_font

    return ws_to_format

Answer 1

我认为问题在于您将单元格的字体属性设置为对齐对象。

在你代码的这一部分你有这个。

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

请注意，在本节的最后一行您有 .....font = header_alignment

尝试将其更改为对齐，看看它是否适合您

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
