Description

The CsvTableSource class is built by defining expected columns to be find in the corresponding csv file.

 

It would be great to throw an Exception when the csv file doesn't have the same structure as defined in the source. For retro-compatibility sake, developers should explicitly set the builder to define columns stricly and expect Exception to be thrown in case of structure difference.

It can be easilly checked with file header if it exists.

Is this possible ?
