如何在pyspark中删除列中的连字符？

from pyspark.sql import SparkSession
from pyspark.sql.functions import regexp_replace

# 创建SparkSession
spark = SparkSession.builder.getOrCreate()

# 创建示例DataFrame
data = [("John-Doe", 25), ("Jane-Smith", 30), ("Mike-Williams", 35)]
df = spark.createDataFrame(data, ["name", "age"])

# 删除列中的连字符
df = df.withColumn("name_without_hyphen", regexp_replace("name", "-", ""))

# 选择需要保留的列
df = df.select("name_without_hyphen", "age")

# 显示结果
df.show()

+-------------------+---+
|name_without_hyphen|age|
+-------------------+---+
|           JohnDoe| 25|
|         JaneSmith| 30|
|      MikeWilliams| 35|
+-------------------+---+
