Spark excel：读取带有多行标题的 excel 文件抛出异常：方法抛出“scala.MatchError”异常

Question

I'm using spark-excel to read excel files, the problem is whenever I use a file with multilines header, the QueryExecution of the dataset throw an exception Method threw 'scala.MatchError' exception. Cannot evaluate org.apache.spark.sql.execution.QueryExecution.toString() Method threw 'scala.MatchError' exception. Cannot evaluate org.apache.spark.sql.execution.QueryExecution.toString()

The only solution for now is to replace the multiline header with a one line, I also tried to replace the column name in the dataset using withColumnRenamed , but it didn't work, is there any way to fix this?

Here's the complete stack:

scala.MatchError: Nom de l'entité <-- Name of the header.
Name of the entity <-- Name of the header.

Steps to reproduce:

    SparkSession session = SparkSession.builder().getOrCreate();
    String path = "testMultiLineHeader.xlsx";
    Dataset<Row> dsBal = session.read().format("com.crealytics.spark.excel")
            .option("location", path)
            .option("sheetName", "Feuil1")
            .option("useHeader", "true")
            .option("treatEmptyValuesAsNulls", "true")
            .option("inferSchema", "true")
            .option("addColorColumns", "false")
            .load(path);
    dsBal.show();
