rules
I went to create a horizontal double line that fills the page after some words. The code
\newcommand{\raisedrule}[2][0em]{\leaders\hbox{\rule[#1]{1pt}{#2}}\hfill}
obtain from LaTeX rule filling the line does most of what I want, but I want the line to be a double line (ie. ======) instead of a single line (ie. ——–).
How can I achieve this?
Addressing only item 4, hiding the tabular inside a macro \logicarg{<premise>}{<conclusion>} might be more appealing:
\documentclass{article}
\newcommand{\logicarg}[2]{% \logicarg{<premise>}{<conclusion>}
\begin{tabular}[t]{@{}l@{}}
#1 \\ \hline #2
\end{tabular}%
}
\begin{document}
\begin{enumerate}
\item \logicarg
{If you are eating soup then I am happy. \\ You are eating soup}
{I am happy}
\item \logicarg
{If it is Wednesday then you aren't taking a quiz. \\ It is not Wednesday.}
{You are taking a quiz.}
\item \logicarg
{Either you love logic or you hate it. \\ You don't hate logic.}
{You love logic.}
\end{enumerate}
\end{document}
For example
\documentclass[11pt]{book}
\usepackage{color}
\usepackage{multirow}
\begin{document}
\begin{center}
\begin{tabular}{c@{} c@{} c@{} c@{} c@{} c@{} c@{} c@{} c@{} c@{} c@{} c@{}}
%\multirow{2}{*}{$-$}&1&5&7&{\huge,}&5&&&5&{\color{white}1}&{\color{white}1}& {\color{white}1}\\
\multirow{2}{*}{$-$}&1&5&7&{\huge,}&5&&&\vline\,5&{\color{white}1}&{\color{white}1}& {\color{white}1}\\
\cline{9-12}
&1&5&&&&{\color{white}1}&{\color{white}1}&3&1&&\\
\cline{2-6}
\multirow{2}{*}{$-$}&&&7&&&&&&&&\\
&&&5&&&&&&&&\\
\cline{2-6}
&&&2&&&&&&&&\\
\end{tabular}
\end{center}
\end{document}

Two options, depending on your usage:
Of course, other fine-tuning is possible.
