Tables are useful for the display of collection of data and are recommended in that case.
Like for the listing of orders or the listing of products of the cart/order.
Nevertheless, any view can be edited in HikaShop via the menu Display->Views.
For example, if you want to change the display of an order, you can edit the file "show" of the view "order".
Note that we are planning on working on improving the design of HikaShop interfaces before the end of the year, in order to implement the support of bootstrap which will be in Joomla 3.0. That will include the removal of all the places where tables shouldn't be used to be replaced with dl/dt/dd or divs
