How to make a subclass thats a half caster

I would like everyone here to try and make a subclass for a fighter like Eldritch Knight and tell me what I am doing wrong I made a copy of Eldritch Knight and did the same thing I added more to my subclass for info and did every configuration possible and I'm upset about this because if its something that's codded into the subclass like warlock hex blades features I'm going to be very upset

i am trying to make a subclass very similar to Eldritch Knight with spellcasting but with different features and not matter what I did I could not get the spell slots to show up. i did find the solution in the class features your have to make a spellcasting table I thought it would create one for me like Eldritch Knight.
