> Column-masking feature supports a number of masking types - like
> mask/mask_first_4/mask_last_4/mask_show_first_4/.. Adding support to enable
> custom value or expression can make this feature easily extendable, to
> address various use cases. For example:
> {noformat}
> - to show only first 4 digits of ccn field, the expression would be
> 'substr({col}, 0, 4)'
> - to show only last 4 digits of ccn field, the expression would be
> 'substr({col}, length({col} - 3)'
> {noformat}
