is there a way to have individual frontend cell permissions by user?
The goal would be to have a collaboration sheet where each user can edit only his cells, e.g. for a workplan that has the rows Name,Mo,Thu … Su and each user can only enter his preferred shift in the row that has his name.
Using table history option, you can create individual tables for each logged in user on your website from one shortcode. You can read more about this option here: https://supsystic.com/documentation/data-tables-plugin-table-history/
But unfortunately there is no option to restrict access for separate columns or rows in the table for required user roles. You can contact us via internal support about possibility to add such option for you.
