Question

通常只是使用带有自定义定义的pandas styler来根据某些条件为数据框的值着色。它很好用，使用了applymap函数。但是，现在我有一个问题，我想运行另一个定义并为满足特定条件的列标签上色（我的列标签只是一堆介于1到100之间的整数）。我在列标签中有一个要被涂成红色的整数列表。

关于如何将样式功能扩展到实际标签而不是单元格的任何想法？

我只尝试使用applymap或apply将函数应用于整个数据框或特定列。

    """
    Takes a scalar and returns a string with
    the css property colour depending on which amino acid set it belongs to   """


    Green = ["S","T","N","Q"]
    Blue = ["K","R","H"]
    Orange = ["F","W","Y"]
    Pink = ["I","L","V","A","M"]
    Red = ["D","E"]
    Purple = ["G","P"]
    Yellow = ["C"]

    if val in Green:
        color = 'green'
        #return ['background-color: %s' if v else '' for val in is_max]
        return 'background-color: %s' % color
    if val in Blue:
        color = 'blue'
        return 'background-color: %s' % color
    if val in Orange:
        color = 'orange'
        return 'background-color: %s' % color
    if val in Pink:
        color = 'pink'
        return 'background-color: %s' % color
    if val in Red:
        color = 'red'
        return 'background-color: %s' % color
    if val in Purple:
        color = 'purple'
        return 'background-color: %s' % color
    if val in Yellow:
        color = 'Yellow'
        return 'background-color: %s' % color
    else:
        color = "white"
        return 'background-color: %s' % color

styled = c.style.applymap(amino_acid_colouring)

styled.to_excel('styled.xlsx', engine='openpyxl')```

“有没有一种方法可以使用pandas.style功能为列/行的实际“标签”上色？
