> Currently, Spark resolves table-valued functions, for example, range, very differently from non-table valued functions. Also, there is no information displayed for table-valued functions. For example:
> {code:scala}
> scala> sql("describe function range").show(false)
> +--------------------------+
> |function_desc             |
> +--------------------------+
> |Function: range not found.|
> +--------------------------+
> {code}
> To make the behavior consistent, we can add a table function registry and resolve the table-valued function from the catalog.
> This also allows Spark to have more built-in table-valued functions in the future.
