Yes you do need to tell contributors what you would like to achieve,the tools and equipment you have to do it, and the experience you have -newbie - exp diyer -what ever. If you can give folks this information it makes it so much easier to help you. Unfortunately these days people tend not to reply to such inquiries as it means much to and fro-ing until suitable information is teased out to be able to provide a viable answer.

If I were to consider building such a table the following points would need to be considered.

1.Fitness for purpose - ie strong enough enough for your intended load.
2.Research prior designs - choose the best that best suits your needs.
3.Make some sort of drawing - from that develop a list of materials
4. from the materials list- make a cutting list.
5. Mark out materials for cutting- match pair and /or mark left and right or front and rear-whatever is applicable.
6.Fabricate and asssemble by tack welding only- checking for square and parallel.
7.Check assemblies for correct movement/function and disassemble.
8.Complete any welding taking care not to everweld thee the fabrication
