Decision table task

Could you please help me to resolve this task?

E-store works with three types of customers according to the total sum of their orders: Regular, Silver and Gold. The list of products to be shown to the client is built according to the rules: products with label Silver or Gold are placed in the top of the list for corresponding types of clients. All the rest products are alphabetically sorted, except the promo products, which have the highest priority and are placed the topmost.

Task:Build decision table based on given information.

Thank you!=)
