Could you fix your table? Somehow tighten it up so it doesn't wobble?
What about painting your chairs all the same color, so they look more tied together? I've seen dining room chairs that didn't match, but they were all painted white so they looked cute together. Maybe add some matching chair pads so they look like one set.
I got my kitchen table in trade. I had a kitchen table that I didn't like, but my former neighbor loved it. I loved hers, but she didn't like it. So we traded, and we've had it ever since.
