The nomenclature groups are:
Acronyms
: two columns (abbrev. - description)
Roman symbols
: three columns (symbol - description - unit)
Greek symbols
: three columns (symbol - description - unit)
...
The symbols should be sorted alphabetically.
My current nomenclature settings:
%----------------------------------------------------------
% Nomenclature
%----------------------------------------------------------
%\renewcommand{\nomname}{List of Symbols and Abbrev.}
\renewcommand\nomgroup[1]{%
\ifthenelse{\equal{#1}{A}}{%
\item[\textbf{Acronyms}] }{% A - Acronyms
\ifthenelse{\equal{#1}{R}}{%
\item[\textbf{Roman Symbols}]}{% R - Roman
\ifthenelse{\equal{#1}{G}}{%
\item[\textbf{Symbols}]}{% G - Greek
\ifthenelse{\equal{#1}{S}}{%
\item[\textbf{Superscripts }]}{{% S - Superscripts
\ifthenelse{\equal{#1}{U}}{%
\item[\textbf{Subscripts }]}{{% U - Subscripts
\ifthenelse{\equal{#1}{X}}{%
\item[\textbf{Other Symbols }]}% X - Other Symbols
{{}}}}}}}}}}
%\ifpdf
\renewcommand{\nomlabel}[1]{\hspace{1 em}#1}%{\hspace{1.5 em}#1}
\renewcommand*{\nompreamble}{\markboth{\nomname}{\nomname}}
Edit1: After using the modified settings, the nomenclature looks like:
Well, the description should be aligned in the mid-column, while Units aligns like symbols at the same line. How to figure this out?
