when opening the "Customer Marketing Leads" example it shows:
- in the column header what type a column contains (i.e. LAST_NAME is indicated as a "us_county")
- records that are invalid (I assume according to the selected profile)
Where can one see these 'profiles (?)' (i.e. a us_county, an email, a city, airport) that are visible if you use the dropdown in the column header.
Can you define these profiles yourself? If so, where?
