Create "page" to add products to a table via input fields

I’m trying to create a page that will show the gear I use for my hobby. It will hold a couple of fields (product name, manufacturer, product category, rating) which I’d like to display in a table. I could obviously make a HTML table and put it all in there, but I’d rather have it in the database. Especially since I’m hoping to do something else with this data at a later point and am hoping to be able to re-use it.

What would be the best way to do something like this? Ideally, I’d like to create one page (just title) and then have some input fields, and be able to either add as many input fields as I’d like, or use one pair of input fields and then update a “table” from which I can delete products again.

Thanks!
