**Note:** The Scala Table API uses Scala Symbols, which start with a single
tick (`'`) to reference the attributes of a `Table`. The Table API uses Scala
implicits. Make sure to import `org.apache.flink.api.scala._` and
`org.apache.flink.table.api.scala._` in order to use Scala implicit conversions.
