Hello Jochen.
You would be able to achieve that only with some custom CSS. You would need to add some conditional formatting to the “stars” column. Like “If cell value > 4.6 set cell content <span class=”stars-container stars-96″>★★★★★</span>” and then you would need to define those classes in wpDataTables settings/Custom JS and CSS/Custom CSS field.
We would be able to explain this in detail on our official support platform.
Please access our official support platform and open a new ticket, and one of our support managers will gladly help. You can access the platform from our official website. Also, due to the rules of www.remarpro.com – we cannot provide a link to our official support platform here.
Kind regards.
