Create a CMS table in a WordPress website

Hi I am a bit of a novice but I have built a responsive eCommerce website using Wordpress running Storefront theme with the Woocommerce plugin. The site is not quite live and I am just finishing it off. I would like a "comparison" tool, basically a comparison table so customers can compare the specifications of two products side by side. I have tried to make one using Tablepress, but long story short... I have ran into problems when viewing on a mobile/internet explorer browsers. Please view this example on both your desktop and mobile: [login to view URL] So that is pretty much what I am trying to achieve apart from I don't really need sub-categories like the example shows (just single categories). I don't know whether I need someone to build a plugin from scratch or just write the code and I copy and paste it in, so feel free to enlighten me on the best way to do this. Once the structure is built, I can manually add the data myself which the table needs to serve depending on the product title that the user searches for. Table features (basically write up of that example): > Search boxes at the top. > Title of product below search box. > Product image below title. > Fixed category column on the left. > Two data columns next to category column (that are able to display text, links and small images). > Adjustable number of rows (so I can add/remove rows in the future). > Compatible with all main browsers. > Responsive for mobile. > Accessible on it's own page, but also via a specific product's page by clicking a link that will open the table readily showing that specific products specifications next to an empty column that they can then search for another product with (Example: Follow this link, then click the "compare" tab [login to view URL] ). I think that is pretty much it. Sorry if I could have explained it better. Feel free to ask as many questions as you want. The example links give the best idea. I don't know how you "hand it over" either so please let me know how you would like to do this one you have done the work. Thanks very much!
