Could someone please point me in the right direction for finding derivations showing how normalised filter table values come about? What should I be searching for to find the derivations?

I've included an example of the type of table that I'm talking about. FilterTable

Most of these classic tables come from the work of Wilhelm Cauer on network synthesis. Such filters are known as Cauer Networks or Cauer Ladders as a result of this work. There is also the Cauer filter which is a special case of such a network. A good book on circuit theory should cover some of this and, if I remember correctly, it involves long division of Laplace polynomials (generalized continued fractions) - not for the faint hearted!
