Question

¿Hay alguna manera de dibujar un cuadro simple con ancho \textwidthy alto para que se llene desde donde esté colocado hasta el margen inferior de la página?

Answer 1

Quizás todavía necesite ajustar algunos parámetros, pero aquí hay una idea vertical \leadersque parece funcionar:

\documentclass[a4paper]{article} % To avoid confusion, let us explicitly 
                                 % declare the paper format.

\usepackage[T1]{fontenc}         % Not always necessary, but recommended.
% End of standard header.  What follows pertains to the problem at hand.

\usepackage{lipsum}

\newcommand*\@helper@hboxto@hsize[2]{%
    \hb@xt@ \hsize {%
        \vrule \@width .4\p@ \@height #1\ht\strutbox \@depth #2\dp\strutbox
        \hfil
        \vrule \@width .4\p@ % automatic height and depth
    }
}
\newcommand*\@helper@hrule{%
    \kern -.2\p@
    \hrule \@height .2\p@ \@depth .2\p@
    \kern -.2\p@
}
\newcommand*\boxcolumnfill{%
    \par
    \vskip \dimexpr \dp\strutbox-\prevdepth
    \@helper@hrule
    \@helper@hboxto@hsize{.25}{.25}%
    \nobreak
    \xleaders \vbox {
                \kern -.25\ht\strutbox
                \@helper@hboxto@hsize{.5}{.5}%
                \kern -.25\dp\strutbox
            }\vfill
    \kern -.25\dp\strutbox
    \nointerlineskip
    \@helper@hboxto@hsize{.25}{0}%
    \@helper@hrule
    \break
}

\makeatother



\begin{document}

With some text before.
\lipsum*[1]
Is the positioning affected by the presence of descenders?
% Uncomment this line to find it out: Qfgjpqy.
\boxcolumnfill

\lipsum[2]

Whole pages of boxes follow.

\newpage
\boxcolumnfill
\boxcolumnfill

Some more text.

\end{document}

Aquí hay otra versión del código, que dota al \boxcolumnfillcomando con un argumento opcional, en el que puede especificar una cantidad de espacio en blanco adicional que se insertará encima de la regla horizontal superior:

\begin{document}

With some text before.
\lipsum*[1]
Is the positioning affected by the presence of descenders?
% Uncomment this line to find it out: Qfgjpqy.
\boxcolumnfill

\lipsum[2]

Some additional space above the rule,\\
without descenders.
% Now with descenders: Qfgjpqy.
\boxcolumnfill[\bigskipamount]

If used at the top of a new page, \verb|\boxcolumnfill| prints a box extending
to the full page height, but any additional space is ignored, even if specified.

\newpage
\boxcolumnfill
\boxcolumnfill[10cm]

This text should be on a new page.  Let's try it again:
\boxcolumnfill[10cm]

\lipsum[3-4]

Now, with an argument that is too tall for the available space:
\boxcolumnfill[15cm]

\textbf{Beware:} a negative argument \emph{is} honored!\\
without descenders.
% Now with descenders: Qfgjpqy.
\boxcolumnfill[-2\baselineskip]

Some more text.

Answer 2

Esto es fácil con tcolorboxel paquete. height fillLa opción crea cuadros con una altura igual al espacio disponible hasta el final de la página:

\documentclass[a4paper]{article} 
\usepackage[T1]{fontenc}         
\usepackage{lipsum}
\usepackage{lmodern}
\usepackage[most]{tcolorbox}

\begin{document}

With some text before.
\lipsum*[1]
\begin{tcolorbox}[height fill]
\end{tcolorbox}

\lipsum[2]
\begin{tcolorbox}[height fill]
\end{tcolorbox}

\begin{tcolorbox}[height fill]
\end{tcolorbox}

\lipsum[1-2]
\begin{tcolorbox}[height fill]
\end{tcolorbox}
