Hello @Anonymous
Ok perfect! Here it's a way to achieve what you want.
1. We need an instant flow that when you run the flow will ask for the supplier to sent the data. Then we are going to look for your table in example 1 to get the items from that supplier. Take a look of the filter query that it['s going to help us retrieving just those items.

List rows in table action need to be set up with your excel table from example 1.
2. Then we are going to look for the email from that supplier with the action Get row. This action need to be set up with your suppliers table.

3. Then, when we have the information, we need to create a Table that is going to be in the email. Please set columns to custom an then add the columns like the image.

Let me know if this works for you!
