How do I remove and re-sort (reindex) columns after applying style in python pandas?

Question

Is there a way to remove columns or rows after applying style in python pandas? And re-sort them?

styled = df.style.apply(colorize, axis=None)
#remove _x columns
yonly = list(sorted(set(styled.columns) - set(df.filter(regex='_x$').columns)))
###Remove columns that end with "_x" here
styled.to_excel('styled.xlsx', engine='openpyxl', freeze_panes=(1,1))

Most things I tried were unavailable, i.e. styled.reindex(columns=yonly) returned AttributeError: 'Styler' object has no attribute 'reindex'

styled.columns = yonly returned AttributeError: 'list' object has no attribute 'get_indexer'

styled = styled[yonly] returns TypeError: 'Styler' object is not subscriptable

After @jezrael's comment to remove columns before styling and colouring, I got my answer :)

The solution was to pass an extra argument, making the original dataframe df available. And coloured the dataframe df_tmp with the "_y" only. :)

df = pd.DataFrame({
    'config_dummy1': ["dummytext"] * 10,
    'a_y': ["a"] * 10,
    'config_size_x': ["textstring"] * 10,
    'config_size_y': ["textstring"] * 10,
    'config_dummy2': ["dummytext"] * 10,
    'a_x': ["a"] * 10
})
df.at[5, 'config_size_x'] = "xandydontmatch"
df.at[9, 'config_size_y'] = "xandydontmatch"
df.at[0, 'a_x'] = "xandydontmatch"
df.at[3, 'a_y'] = "xandydontmatch"
print(df)

def color(x, extra):
    c1 = 'color: #ffffff; background-color: #ba3018'
    df1 = pd.DataFrame('', index=x.index, columns=x.columns)

    #select only columns ends with _x and _y and sorting
    cols = sorted(extra.filter(regex='_x$|_y$').columns)
    #loop by pairs and assign style by mask
    for colx, coly in zip(cols[::2],cols[1::2]):
        #pairs columns 
        m = extra[colx] != extra[coly]
        df1.loc[m, [coly]] = c1
    return df1

yonly = list(sorted(set(df.columns) - set(df.filter(regex='_x$').columns)))
df_tmp = df[yonly]
df_tmp.style.apply(color, axis=None, extra=df).to_excel('styled.xlsx', engine='openpyxl')

Thank you wonderful people of SO! :D
