Not a full table, but I have had a couple of orders for fixturing over the last 6 months via Fireball.eu
Went all OK, delivered in a few days from Czech Republic via FedEx.
They were invoiced ex-VAT as an export from EU, so I Paid 20% import VAT, around 4% duty and £5-10 deferment fee.
Should be much the same for stuff that needs to come from the US.
Presumably mostly the usual VAT on the import, though? There would have been a small deferment fee (£10ish) and 4% Duty due. This would be the same for any tables imported from the EU, such as those from Poland or Germany.
Fireball EU would have priced it as a non-VAT export from the EU, but VAT is due on import to the UK. Stuck with, of course, it if you’re purchasing as a private individual or non-VAT registered company, same as a UK purchase.
Sales to the EU will have local 21% Czech VAT added on by Fireball EU.
Just another fun Brexit admin hassle for importers.
