Description

In TypeStringUtils.readTypeInfo:

    case _: BasicArrayTypeInfo[_, _] | _: ObjectArrayTypeInfo[_, _] |
         _: PrimitiveArrayTypeInfo[_] =>
      throw new TableException("A string representation for array types is not supported yet.")

This exception makes us unable to create a table schema or format schema with a array type field.

I'm not sure whether this is an improvement or not, because you throw an exception explicitly here.
