It sounds like a lovely table actually. Remove the other chairs, and if possible have a lovely table cloth. I have a length of inexpensive red fabric that I got years ago, and it comes out every year to do a stellar job. Some day I will hem it!
In any case lay your settings for two deciding on formal or informal. Bottle of wine (if having) in coaster, candles in candlestick and a few lower ones, bottle/jugs of water, center piece, sparkling glasses, shined up cutlery etc. I light candles even if we eat in daylight because why not? Don't forget a cracker on the plates!
Rather that plate everything in the kitchen bring serving bowls to the table.
Fill the rest of the table with deserts, cheeses and fruits, your mince pies, shiny red apples piled high, a bowl of clementines, a few chocolates on a plate, small trifle etc. All of their colours and textures will bring real warmth and abundance to the table. We always have a pudding to flame, it is fun and is a once a year event!.
Don't forget your lighting - nothing too harsh over head.
There is a fun show on Netflix called Lords and Ladles. It is set in Ireland. They have a few chefs who go to various castles to cook a menu, usually from about 100 + years ago. It can be quite funny actualy but there are many interesting serving methods that you can use for your Christmas Day lunch, even if (like me) you do not live in a castle. I bet it will be lovely!
