Hi @twalthr , I addressed the comments. Thank you for your suggestion. I
add some tests that getting schema from tables in existing ITCases.
> Add possibility to get column names
> -----------------------------------
>
> Key: FLINK-4686
> URL: https://issues.apache.org/jira/browse/FLINK-4686
> Project: Flink
> Issue Type: New Feature
> Components: Table API & SQL
> Reporter: Timo Walther
> Assignee: Jark Wu
> Labels: starter
>
> For debugging and maybe for visualization in future (e.g. in a shell) it
> would be good to have the possibilty to get the names of {{Table}} columns.
> At the moment the user has no idea how the table columns are named; if they
> need to be matched with POJO fields for example.
> My suggestion:
> {code}
> Schema s = table.schema();
> TypeInformation<?> type = s.getType(1);
> TypeInformation<?> type = s.getType("col");
> String s = s.getColumnName(1);
> String[] s = s.getColumnNames();
> {code}
