Выход
Вопрос
Есть ли простой способ выровнять символы, единицы измерения и описания? Я бы хотел избежать использования таблиц для выравнивания. Я бы хотел что-то вроде:
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
решение1
Это возможное решение использует технику, представленную вСписок описаний с выровненными описаниямии определить макрос с именем aboxbox длиной 3 см с выравниванием по левому краю для символов, чтобы установить выравнивание по второму столбцу.

Если вы просто хотите использовать descriptionсписок и сделать так, какДэвид предложил, вставляя все в описание элемента, можно получить дешевое выравнивание с помощью \rlapи \phantom. (Обратите внимание, аргументы двух \phantomкоманд должны быть самыми длинными записями в полях «символ» и «единица измерения» соответственно.)
\documentclass{article}
\usepackage[official]{eurosym}
\usepackage[utf8]{inputenc}
\newcommand\itemd[2]{\item[\rlap{#1}\phantom{$CMAT_{(W<W_L)}$} \rlap{(#2)}\phantom{\euro{}

(Публикую CW, поскольку мне не очень нравится этот вывод: при наличии множества символов и единиц измерения разной длины любой выровненный вывод будет выглядеть неуклюже.)
