By adding table salt, some of the potassium soap will be converted into sodium soap as well as playing with the solubility of soap in a brine (table salt solution.) If a person's goal is to make a pure potassium soap, it's kind of counterproductive to use table salt. The chemist type in me wants to point that out for those who might not know.
But I realize you are just using up stuff you already have and having fun exploring this aspect of soapmaking. S'all good.
I followed the link above to the Natural Soap article. It says this at the end -- "...To make your own Potassium Hydroxide, or potash you collect ashes and percolate water through them and collect it...."
Lye made from wood ashes is mostly potassium carbonate with perhaps some sodium carbonate depending on the type of plant material used. The common name given is incorrect. Potassium hydroxide is caustic potash. Potassium carbonate is just potash.
