Thank you for the suggestions
DeathSlam . When I clicked on the Thread Tools dropdown menu and selected Create a Wikipost I could not see any option to upload an image, I could make a URL though. So I'll no doubt to do something wrong if I attempt creating a wiki, but I'm happy to send on the table or an image of it if someone else wants to create it. I found the colours useful in the table to highlight the cabin classes for a quick glance, so not sure how that can be captured using a code block table (which in your example looks similar to Notepad text file).
I added a wiki and put your image there by using the URL of the file you already uploaded.
Unfortunately there isn't a way to embed a proper table in an FT post, using a CODE block is the best you can do, it's not great, but if you want to embed a table where people can copy the text content directly, it's the best you can do without hosting it offsite.
I do think the colours are useful and good, you can put coloured text in code blocks, but not change the background colour.
Code:
