Text Formatting ⇒ How do I uniformly typeset tabbing in enumerate?

[Stefan Kottwitz]

Well, the line break goes away when I insert an \mbox{} before.

Thanks for support. The code works well.

How do I make the table fill the width of the surrounding enumerate item? Is there a way to obtain the width of the surrounding enumerate item?

Code: Select all

\documentclass[oneside,12pt]{article}
\usepackage[showframe]{geometry}
\usepackage{microtype}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage{enumitem}
\setlist[enumerate,1]{label=\bfseries\Alph*,align=left,leftmargin=*,
labelsep=1.5em}
\setlist[enumerate,2]{label= (\arabic*),leftmargin=*,align=right}
\usepackage{tabularx}
\newcounter{tab}
\renewcommand*{\thetab}{(\arabic{tab})}
\begin{document}
\begin{enumerate}
	\item No philosopher is illogical. Jones keeps making argumentative blunders.
		No logical person keeps making argumentative blunders. All existentialists are
		philosophers. So, Jones is not an existentialist.

		\setcounter{tab}{0}
		\begin{tabularx}{\linewidth}{@{}>{\refstepcounter{tab}\thetab}rX@{\quad\quad}l@{}}
			\label{first}& No philosopher is illogical. &(premiss) \\
			\label{second}& Jones keeps making argumentative blunders. &(premiss) \\
			& No logical person keeps making argumentative blunders.
			& (premiss) \\
			& All existentialists are philosophers. & (premiss) \\
			& Jones is illogical & (from~(2) and~(3))\\
			& Jones is not a philosopher. from~\ref{first} and~\ref{second}\\
			& So, Jones is not an existentialist.
		\end{tabularx}
\end{enumerate}
\end{document}

What is \thetab? Ah, it's defined in preamble.
Why do you insert @{} in preamble of tabularx? It doesn't seem to make a difference.

[Johannes_B]

\thetab[\latex] defines the graphical representation of the tab counter.
In this case, this is an opening parenthesis, the value of the counter in arabic numerals (possible would be also roman, Roman, alph and Alph numerals) and a closing paren.

The other question is dealt with in the followup: [url=http://latex-community.org/forum/viewtopic.php?p=93039#p93039]Why do people insert @{} in table preamble?[/url]

Great.

@Stefan, neither hbox nor label enter horizontal mode. But the reerence point is moved, see texdoc grfguide, page 6, footnote dor reference.
