如何将非统一日期格式的字符串表示形式填充的DataFrame中的一列数据转换为datetime？

import pandas as pd

data = {'date_column': ['2022-01-01', '2022-02-01', '2022-03-01', '2022-04-01', '2022-05-01', '2022-06-01'],
        'value_column': [10, 20, 30, 40, 50, 60]}
df = pd.DataFrame(data)

df['date_column'] = pd.to_datetime(df['date_column'])

print(df.dtypes)
print(df)

date_column    datetime64[ns]
value_column            int64
dtype: object

  date_column  value_column
0  2022-01-01            10
1  2022-02-01            20
2  2022-03-01            30
3  2022-04-01            40
4  2022-05-01            50
5  2022-06-01            60
