>             Project: Flink
>          Issue Type: Improvement
>          Components: API / Table SQL

> What I would like to achieve is to change the following code
> {code}
>     val table = data.flatMap(line=>line.split("\\s"))
>       .map(w => (w, 1))
>       .toTable(tEnv, 'word, 'count)
> {code}
> to this
> {code}
>     val table = data.flatMap(line=>line.split("\\s"))
>       .map(w => (w, 1))
>       .toTable('word, 'count)
> {code}
> The only change is that tableEnv is removed in method toTable.  I think the second piece of code is more readable. We can create TableEnvironment based on the ExecutionEnvironment of DataSet/DataStream rather than asking user to pass it explicitly.
