trait Table extends AnyRef
An interface representing a logical structured data set of a data source. For example, the implementation can be a directory on the file system, a topic of Kafka, or a table in the catalog, etc.
This interface can mixin SupportsRead and SupportsWrite to provide data reading
and writing ability.
The default implementation of #partitioning() returns an empty array of partitions, and
the default implementation of #properties() returns an empty map. These should be
overridden by implementations that support partitioning and table properties.

Abstract Value Members
- abstract def capabilities(): Set[TableCapability]
Returns the set of capabilities for this table.
- abstract def name(): String
A name to identify this table.
A name to identify this table. Implementations should provide a meaningful name, like the database and table name from catalog, or the location of files for this table.
- abstract def schema(): StructType
Returns the schema of this table.
Returns the schema of this table. If the table is not readable and doesn't have a schema, an empty schema can be returned here.
