You are not responsible for objects other people have a sentimental attachment to - the memories and sentiments are theirs, not yours, so why should you be lumbered with housing a fugly oversized thing you don’t want or need?
That may sound cold, especially if the person who’s willed it to you has done so out of love for you as well as for the table, but ultimately it’s madness to let other people dictate what’s in your home (said has someone who’s spent a lifetime fending off ‘family’ stuff). And you can’t guarantee what’ll happen to it when you’re gone, especially if no one else in your family wants or has space for it. At some point it’ll inevitably be rehomed, so just bite the bullet now.
I’d give other family members the opportunity to take it if they wish, and if there’s no interest then sell it and use the money to buy something that you love, which will remind you of your relative whenever you use/wear/look at it.
If it’s very hard for you to let go without guilt, try the Kondo method, where you take a bit of time to fully appreciate the object and think about the person who gave it to you, and let it go with gratitude for its service and the hope it’ll have a new life being loved and appreciated by someone else. Sounds like a right load of nonsense written down, but psychologically it’s quite a useful technique for freeing yourself of that horrible feeling of obligation when getting rid of gifts and inheritances.
