I'm a member of several different module groups, all use different module heights. The HO group uses 42" (adjustable from 41"-43") from floor to top of rail, the On30 group uses a height of 36" to 38". The higher tables are typical for many modules, and this height gets the trains a bit closer to eye-level, but only two legs can be cut from an eight foot board, so there is no economy of materials advantage to making the legs less than 48" in length.
The lower On30 module height was decided upon by the group as a concession to the guests at a show who may be in wheelchairs or mobility scooters, as well as the younger set who see it as close to their eye-level. If I had it to do over again, I would make those legs 31"or 32". At this height, material for three legs can be cut from a standard 8' board (rather than just two), resulting in less material waste during construction, and the subsequent loss of a couple of inches of table height isn't that noticeable.
Since you you are only going be setting up in your basement, your table height should be what you are most comfortable with.
