All products (categories and manufactures) are template-based. Currently there're only one template for products. You can find it here \Templates\Products\VariantsInGrid.ascx But you can create new templates. So each product can have a different template.
Sorry, Hate to be probbaly a bit stupid, but where is Templates\Products\VariantsInGrid.ascx, and can I alter it? as you can tell I am not a developer. All I want to do is make the Product Variant Name left justified, it appears to be right justified
