Pregunta
¿Existe alguna forma sencilla de alinear símbolos, unidades de medida y descripciones? Me gustaría evitar el uso de tablas para alinear. Me gustaría algo como:
SYMBOL (Units) Long long long long long long long long long long long long long
SYMBOL_2 (Units) Long long long long long long long long long long long long long
Long long long long long long long long long long long long long

Esta posible solución utiliza la técnica introducida enLista de descripciones con descripciones alineadasy definir una macro llamada aboxcaja de 3cm de largo, con alineación a la izquierda, para los símbolos, de manera que se establezca una segunda alineación de columnas.

Si solo desea utilizar una descriptionlista y hacer lo queDavid sugirió, al incluir todo en la descripción del artículo, puede obtener una alineación económica usando \rlapy \phantom. (Tenga en cuenta que los argumentos de los dos \phantomcomandos deben ser las entradas más largas en los campos "símbolo" y "unidad", respectivamente).
\documentclass{article}
\usepackage[official]{eurosym}
\usepackage[utf8]{inputenc}
\newcommand\itemd[2]{\item[\rlap{#1}\phantom{$CMAT_{(W<W_L)}$} \rlap{(#2)}\phantom{\euro{}

(Publicar CW porque no me gusta mucho este resultado: con muchos símbolos y unidades de longitudes diferentes, cualquier resultado alineado parecería incómodo).
