Hi @kultura-luke , thank you for opening this PR. Of course we can consider adding the fixed header extension, but a bit more work will be required. For instance we will have to add it to the dt_for_itables package - it's currently not included, cf. https://github.com/mwouts/itables/blob/main/packages/dt_for_itables/package.json#L35

I can take care of doing that, or alternatively, if you want to try it on your end, this is the documentation: https://mwouts.github.io/itables/custom_extensions.html#creating-a-custom-datatables-bundle

That's strange because I swear it was working already, or perhaps I just got mixed up with the scrollY behaviour?

I'm not entirely sure how to verify that it's working so if you could take that on that would be great 🙏

Yes will do! Cheers
