Looking for a Developer to fix two things on my website

I have a Wordpress website called Smoothmaths.co.uk. I am using a table plugin called supsystic and I need to fix somethings with it. If you go to this link https://smoothmaths.co.uk/quadratic-sequences it shows an example of one of the tables. The view looks different on pc than on mobile. I want to be able to see the whole worksheet on mobile without lines exactly like on pc. The second issue is with this plugin it automatically refreshes and there is a feature to use one cell from the table but that doesn’t want to refresh. If you have any questions let me know.
