% \begin{abstract}
% This package defines some environments that adds
% a height specification to tabular and array.
% \end{abstract}
%
% \tableofcontents
%
% \section{Usage}
%
% \begin{quote}
% |\usepackage{tabularht}|
% \end{quote}
% The package provides the following environments
% that extend the tabular/array environment by
% a height specification as first argument:
% \begin{itemize}
% \item |tabularht|, |tabularht*|
% \item |arrayht|
% \item |tabularhtx|
% (if package \xpackage{tabularx} is loaded)
% \end{itemize}
% The height argument allows a length specification,
% package \xpackage{calc} is supported if used. This means,
% the tabular will have the specified height.
% You can also use the prefixes |to=| and |spread=|.
% |to=| is the default, |spread=| means, the natural
% height of the tabular box is changed by the length
% after |spread=|.
%
% Examples:
% \begin{quote}
% \begin{tabular}{@{}l@{ $\rightarrow$ }l@{}}
% |\begin{tabularht}{1in}|
% & height is 1in\\
% |\begin{tabularht}{to=1in}|
% & height is 1in\\
% |\begin{tabularht}{spread=0pt}|
% & natural height, same as |\begin{tabular}|\\
% |\begin{tabularht}{spread=1in}|
% & natural height increased by 1in
% \end{tabular}
% \end{quote}
%
% Hint: See also package \xpackage{tabularkv}, it provides an interface,
% where most parameters for the environments can be given
% by key-value pairs.
%
% \begin{declcs}{interrowspace}\,|{|\dots|}|
% \end{declcs}
% Adds space between table rows. It is essentially
% the same as |\noalign{\vspace{...}}|.
% \begin{declcs}{interrowfill}
% \end{declcs}
% Short for |\interrowspace{\fill}|
% \begin{declcs}{interrowstart}\,\dots\,\cs{interrowstop}
% \end{declcs}
% Marker commands, useful for option \xoption{vlines}.
%
% \subsection{Option \xoption{vlines}}
%
% Warning: This stuff is experimental.
%
% \vspace{2ex}
% \noindent
% Vertical lines are interrupted, if space is inserted
% in \cs{noalign}, \cs{interrowspace}, \cs{addlinespace}
% (\xpackage{booktabs}),
% between double \cs{hline}s. This option tries to detect
% and add the vertical lines. The lines in a tabular
% with \xpackage{tabularht} support (environments of this package)
% are numbered from left to right. The gap that is
% controlled by \cs{interrowspace} or in between \cs{interrowstart}
% and \cs{interrowstop} is then filled with the detected
% vertical lines.
%
% If only a limited selection of the lines should be
% drawn, the commands know an optional argument with a
% list of line numbers, e.g.
% \begin{quote}
%\begin{verbatim}
%\begin{tabularht}{50mm}{|l|l|}
% Hello & World\\
% \interrowfill[1,3]
% Foo & Bar
%\end{tabularht}
%\end{verbatim}
% \end{quote}
% There are three lines, but the middle line is not drawn
% in the gap between the first and second row.
% Zero can be used to suppress all lines:
% \begin{quote}
% |\interrowspace[0]{10mm}|
% \end{quote}
% The syntax of the commands with the optional argument
% with the line number list \meta{list}. \meta{list} is a comma
% separated list of numbers, \meta{height} means the
% height specification described above with the optional
% prefixes |to=| or |spread=|.
% \begin{quote}
% \cs{interrowspace}\,|[|\meta{list}|]|\,|{|\meta{height}|}|\\
% \cs{interrowfill}\,|[|\meta{list}|]|\\
% \cs{interrowstart}\,|[|\meta{list}|]|\,\dots\,\cs{interrowstop}
% \end{quote}
%
% Option \xoption{vlines} is driver dependent and uses \eTeX\ features.
% \begin{description}
% \item[\xoption{pdftex}:] \pdfTeX\ in PDF mode.
% Here the positions of the lines are written with the
% help of the \cs{pdfsavepos} feature into the \xfile{.aux} file(s).
% Therefore you need two LaTeX runs to get the lines.
% \item[\xoption{dvips}:]
% Here, PostScript's currentpoint it used to get
% the line positions. The lines are then drawn at the end
% of the page. Thus one \LaTeX/dvips run is sufficient
% for this option.
% \item[Other drivers:]\mbox{}
% \begin{description}
% \item[PostScript drivers:] probably possible, an end of page
% hook would be nice.
% \item[\VTeX:] with GeX (PostScript interpreter) probably possible.
% \item[dvipdfm:] no idea. The big problem is, how to get the
% current position?
% \end{description}
% \end{description}
%
% \subsection{Limitations}
%
% \begin{itemize}
% \item
% Vertical lines are interrupted by |\noalign{\vfill}|.
% \end{itemize}
%
% \subsection{Compatibility}
%
% \begin{itemize}
% \item
% \xpackage{array}, \xpackage{delarray}, \xpackage{tabularx}
% are supported.
% \item There can be problems with packages that
% redefine \cs{@array} (or \cs{@@array}, \cs{@tabarray}) and
% \cs{@arrayrule} (for option \xoption{vlines}).
% \item \xpackage{colortbl}: it should at least work, but there isn't
% support for filling the gaps with color, neither
% the rules nor the backgrounds.
