Hello Team,
customers are not able to add tables and panels while creating service requests via the customer portal in the description field. The description field is already configured with "Wiki Style Renderer" and when agents create the tickets via the JSM agent view they are able to add tables/Panels in the description field but customers are not able to add tables and panels while entering descriptions in the customer portal. Please enable this feature in customer portal as well.
