You will soon experience the odd paradox of DIY wood working. To build a workshop table, you really need a… workshop table to build it.
This is also true for most other things like, cutting jigs, router table, etc.
When I started wood working, I took a brief intro to wood working course at a local WoodCraft store. They have a big well-equipped shop, a Woodworker's Club, and part of the course was a pitch to join their club, but the course was still worthwhile. I never took wood shop in junior high school.
