   Concatenates multiple input string columns together into a single string column, using the given separator.

   Example:

   1. df.withColumn("res", concatWs("-".lit, col("col1"), col("col2")))
        .show(false)
          +----+----+----+
          |col1|col2| res|
          +----+----+----+

          +----+----+----+

   Note

   even if cols contain null columns, it prints remaining string columns (or empty string).
