Creating a table visual based on other table visuals by grouping column

Hello,

I am creating a PowerBI dashboard to calculate the cost of buying tables from different suppliers. There are a total of 3 suppliers which provide either tabletop and legs separately or tabletop and legs together.

This data has been consolidated in one dataset with the following structure: Supplier, tabletop.material, tabletop.dimensions, leg.height, unit.cost.
For example when the leg is sold separately the tabletop.material and tabletop.weight will be NA.

The user then inputs their wished table specification in slicers and powerbi shows the result in table visuals. I was able to create 3 table visuals which each have the cost for leg only, table only or leg + table.

The issue that I face is that these tables combine different suppliers. For the purpose of the user, I would like to have one table visual per supplier. For example, for supplier Akielo, we would have one row for legs only + cost, one row for tabletop only + cost and total cost for this supplier.

I have also supplied the PowerBI file. https://we.tl/t-tStp4iFkhV
