 * Is it possible to put a validation to enter or edit records, where do you want
   a column to have a validation to not allow entering existing data? like email,
   for example? That it is not allowed to enter an email that already exists in 
   the column?

 * Hello,
   We currently do not have any ‘data validation’ as an ‘out of the box’ 
   feature.There can be a custom workaround for SQL based tables in our premium 
   Plugin version for editable tables, where you would set a [Unique constraint in MySQL](https://www.w3schools.com/sql/sql_unique.asp)
   through your Database Tool directly;but on this Forum we only discuss features
   for our Lite Plugin version.So, if you wish to ask more details about this, please
   open a ticket on our [main Support platform here](https://tmsplugins.ticksy.com/),
   and one of our Agents will respond as quickly as possible.
 * If you don’t have a licence (or if it expired), please open a [pre-purchase ticket](https://tmsplugins.ticksy.com/submit/#100010481)
   which doesn’t require a purchase code.
 * Premium products are not supported in these forums, as per [this comment](https://wordpress.org/support/topic/error-when-not-logged-into-wordpress-backend/#post-15050671)
   by WordPress.org moderators.
 * Thank you for understanding. 
 * Kind regards.
