Description

When a SerDe creates columns dynamically during table creation, there is no checking done on the validity of the created column names. This means that it's possible to create a table that contains columns that can't be queried, and will lead to issues when trying to query the created table.

The same column name validation should be performed for dynamically-created columns as for other column names.

This behavior can be easily tested using the TestSerDe, and including a column name that includes an invalid identifier character (e.g. a period) in the list of columns to create.
