> 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 ?
