> {{ColumnName}} defines methods to create {{StructFields}}.
> It'd be very user-friendly if there were methods to create {{StructFields}} with explicit {{nullable}} property (currently implicitly {{true}}).
> That could look as follows:
> {code}
> // E.g. def int: StructField = StructField(name, IntegerType)
> def int(nullable: Boolean): StructField = StructField(name, IntegerType, nullable)
> // or (untested)
> def int(nullable: Boolean): StructField = int.copy(nullable = nullable)
> {code}
