+**Note:** Table API and SQL queries can be easily integrated with and
embedded into DataStream or DataSet programs. Have a look a the [Integration
with DataStream and DataSet API](#integration-with-datastream-and-dataset-api)
section to learn how DataStreams and DataSets can be converted into Tables and
vice versa.

Create a TableEnvironment

possible to combine Tables of different TableEnvironments.

The format need modify because I have builded the docs, And see the format
as follows:
The TableEnvironment is a central concept of the Table API and SQL
integration. It is responsible for: * Registering a Table in the internal
catalog * Registering an external catalog * Executing SQL queries * Registering
a user-defined (scalar, table, or aggregation) function * Converting a
DataStream or DataSet into a Table * Holding a reference to an
ExecutionEnvironment or StreamExecutionEnvironment
-
We want:
* Registering a Table in the internal catalog
* Registering an external catalog
* Executing SQL queries
* xxx
Right?
