如何绘制以date作为列名、以time作为行标签的数据帧？

import pandas as pd

df = pd.DataFrame(columns=['date'])

time = ['09:00', '10:00', '11:00', '12:00']
for t in time:
    df.loc[t] = None

df.at['09:00', 'date'] = '2022-01-01'
df.at['10:00', 'date'] = '2022-01-02'
df.at['11:00', 'date'] = '2022-01-03'
df.at['12:00', 'date'] = '2022-01-04'
