I have generated a nomenclature for my document and the horizontal spacing between the symbol and the definition stays constant no matter how long the symbol is. For example:
\documentclass{article}
\usepackage{amsmath}
\usepackage{nomencl}
\makenomenclature
\begin{document}
Example of nomenclature
\nomenclature{TIARLW}{This is a really long word}
\nomenclature{TOA}{This one also}
\nomenclature{a}{another}
\nomenclature{$\partial{u}/\partial{z}$}{Here's another one}
\printnomenclature
\end{document}
resulting in

How is it possible to make the nomenclature so that each of the definitions are aligned? Is it possible to treat this as a table?
