你可以做一个左连接和分配 False 如果所有列从 df2 为空：

import pyspark.sql.functions as F

result = df1.alias('df1').join(
    df2.alias('df2'),
    F.least(*[F.expr(f'df1.{c} = df2.{c}') for c in df1.columns]), 
    'left'
).select(
    [
        (~F.greatest(*[F.col(f'df2.{c2}').isNull() for c2 in df2.columns])).alias(c)
        for c in df1.columns
    ]
)

result.show()
