this is something you have to measure your own needs for---my table is 30" high and works good for me- but you said 29" is too tall for you---it also depends on your chair===you could try using a (folding table-like a card table) with adjustable legs and try different heights until you find the right combination for you---we are all different- and what works for one may not work for the next...
if you try with a table with adjustable legs-remember you need to use the chair you are going to be using---since chairs fit us at different heights too- i'm one of those people with long legs but a short body---when i drive the seat has to be back for me to not have my knees on the steering wheel-but at a normal height i look tiny behind the wheel-can just barely see over it---so have to raise the seat---
it is nice when you have a good ergonomic adjustable chair you can also fit to you.
congradulations on the renovations! i hope you manage to make your space perfect for you!
