如何删除pyspark dataframe中引号之间的空格？

from pyspark.sql.functions import regexp_replace
from pyspark.sql.types import StringType

def remove_spaces_between_quotes(value):
    pattern = r'(?<=")\s+(?=")'
    return regexp_replace(value, pattern, "")

spark.udf.register("remove_spaces_between_quotes", remove_spaces_between_quotes, StringType())

df = df.withColumn("column_name", remove_spaces_between_quotes(df["column_name"]))
