如何从org.apache.spark.sql.Column中检索名称和类型？

import org.apache.spark.sql.{Column, SparkSession}
import org.apache.spark.sql.types.DataType

object ColumnInfoRetriever {
  def retrieveNameAndType(column: Column): (String, DataType) = {
    val name = column.name
    val dataType = column.dataType
    (name, dataType)
  }

  def main(args: Array[String]): Unit = {
    val spark = SparkSession.builder()
      .appName("ColumnInfoRetriever")
      .master("local")
      .getOrCreate()

    import spark.implicits._

    val data = Seq(("Alice", 25), ("Bob", 30), ("Charlie", 35))
    val df = data.toDF("name", "age")

    val column = df("name")
    val (name, dataType) = retrieveNameAndType(column)

    println(s"Column name: $name")
    println(s"Column type: $dataType")
  }
}
