Fixed Header and Responsive Table, first website I ever build, please help!

Hi there!

My table from TablePress Version 1.8.1 needs a fixed header and I think it needs to be responsive ‘scroll’ as well to look good on mobile but this doesn’t work for me yet.

I’ve installed the plugins properly for both and to try to get the fixed header I changed the code to: [table id=2 datatables_fixedheader=top datatables_fixedheader_offsettop=60/]

Though, nothing seems to happen. Can you please help me with this? And which code should I use to combine it with being responsive? The images become very small on smaller devices..

Any help would be greatly appreciated! Thanks
