Custom odoo module - how to make a table - odoo

Question

I am creating a custom module with additional part numbers on a separate tab in the products screen. I have built the module, but am having trouble figuring out how to display the information so it matches the layout in the attached image. I have tried tree view but have not been able to get the fields on the same line. Can this only be accomplished through css or is there a table view that I am not aware of?
I also need to make sure that all of the information in row 1 stays tethered together for additional forms, etc. My plan is to make the field names for each row end with a different number (i.e. x_mfrname1,x_mfrpn1,x_mfrname2,x_mfrpn2, etc.). Can somebody please just tell me if I am on the right track. This is the initial Odoo setup for a client of mine and I don't want them to come back to me down the line and find out I forgot something. I have been scouring the internet and reading a few books but I am not completely confident.
Here is a link to a layout of what I am talking about:

Thanks!
