% \section{Introduction}
%
% The \package{longtable} package defines a new environment,
% \DescribeEnv{longtable}
% \env{longtable}, which has most of the features of the \env{tabular}
% environment, but produces tables which may be broken by \TeX's
% standard page-breaking algorithm. It also shares some features with
% the \env{table} environment. In particular it uses the same counter,
% \texttt{table}, and has a similar "\caption" command. Also, the
% standard "\listoftables" command lists tables produced by either the
% \env{table} or \env{longtable} environments.
%
% The following example uses most of the features of the \env{longtable}
% environment. An edited listing of the input for this example appears
% in Section~\ref{listing}.
%
% \textbf{Note:} Various parts of the following table will
% \textbf{not} line up correctly until this document has been run
% through \LaTeX\ several times.  This is a characteristic feature of
% this package, as described below.

%
% \section{Chunk Size}
%
% \DescribeMacro{LTchunksize}
% In order to \TeX\ multi-page tables, it is necessary to break up the
% table into smaller chunks, so that \TeX\ does  not have to keep
% everything in memory at one time. By default \env{longtable} uses 20
% rows per chunk, but this can be set by the user, with e.g.,
% "\setcounter{LTchunksize}{10}".\footnote
%    {You can also use the plain \TeX\ syntax
%    {\ttfamily\v\\LTchunksize=10.}}
% These chunks do not affect page breaking,
% thus if you are using a \TeX\ with a lot of memory, you can set
% "LTchunksize" to be several pages of the table. \TeX\ will run
% faster with a large "LTchunksize". However, if necessary,
% \env{longtable} can work with "LTchunksize" set to 1, in which case
% the memory taken up is negligible.
% Note that if you use the commands for setting the table head or foot
% (see below), the "LTchunksize" must be at least  as large as the
% number of rows in each of the head or foot sections.
%
% This document specifies "\setcounter{LTchunksize}{10}".  If you look
% at the previous table, after the \emph{first} run of \LaTeX\  you will
% see that various parts of the table do not line up.
% \LaTeX\ will also have printed a warning that the column
% widths had changed. \env{longtable} writes information onto the
% ".aux" file, so that it can line up the different chunks.
% Prior to version~4 of this package, this information was not used
% unless a "\setlongtables" command was issued,  however, now the
% information is always used, using a new algorithm\footnote{Due to
% David Kastrup.} and so "\setlongtables" is no longer needed. It is
% defined (but does nothing) for the benefit of old documents that
% use it.
%
% \begin{table}
% \centering
% \begin{tabular}{||l|l|l||}
% \hline\hline
% A&\env{tabular}& environment\\
% \hline
% within&a floating&\env{table}\\
% \hline\hline
% \end{tabular}
% \caption{A floating table}
% \end{table}
%
% \section{Captions and Headings}
%
% At the start of the table one may specify lines which are to appear at
% the top of every page (under the headline, but before the other lines
% of the table).
% \DescribeMacro{\endhead}
% The lines are entered as normal, but the last "\\" command is
% replaced by a "\endhead" command.
% \DescribeMacro{\endfirsthead}
% If the first page should have a different heading, then this should be
% entered in the same way, and terminated with the "\endfirsthead"
% command. The "LTchunksize" should be at least as large as the
% number of rows in the heading.
% \DescribeMacro{\endfoot}
% There are also "\endfoot" and "\endlastfoot"
%\DescribeMacro{\endlastfoot}
% commands which are used in the same way (at the \emph{start} of the
% table) to specify rows (or an "\hline") to appear at the bottom of
% each page. In certain situations, you may want to place lines which
% logically belong in the table body at the end of the \env{firsthead},
% or the beginning of the \env{lastfoot}. This helps to control which
% lines appear on the first and last page of the table.
%
% \DescribeMacro{\caption}%
% The "\caption{...}" command is essentially equivalent to\\
% "\multicolumn{n}{c}{\parbox{\LTcapwidth}{...}}"\\
% where \texttt{n} is the number of columns of the table. You may set
% the width of the caption with a command such as
% "\setlength{\LTcapwidth}{2in}"
% in the preamble of your document. The default is 4in. "\caption" also
% writes the information to produce an entry in the list of tables. As
% with the "\caption" command in the \env{figure} and \env{table}
% environments, an optional argument specifies the text to appear in the
% list of tables if this is different from the text to appear in the
% caption. Thus the caption for table \ref{long} was specified as
% {\ttfamily
%  "\caption"[An optional table caption
%             (used in the list of tables)]\v{A long
%  table"\label{long}"\v}}.
%
% You may wish the caption on later pages to be different to that on the
% first page. In this case put the "\caption" command in the first
% heading, and put a subsidiary caption in a "\caption[]" command in
% the main heading. If the optional argument to "\caption" is empty,
% no entry is made in the list of tables. Alternatively, if you do not
% want the table number to be printed each time, use the "\caption*"
% command.
%
% The captions are set based on the code for the \package{article}
% class.
% If you have redefined the standard "\@makecaption" command to produce
% a different format for the captions, you may
% need to make similar changes to the \package{longtable} version,
% "\LT@makecaption". See the code section for more details.
%
% A more convenient method of customising captions is given by the
% \package{caption(2)} package, which provides commands for customising
% captions, and arranges that the captions in standard environments, and
% many environments provided by packages (including \package{longtable})
% are modified in a compatible manner.
%
% You may use the "\label" command so that you can cross reference
% \env{longtable}s with "\ref". Note however, that the "\label" command
% should not be used in a heading that may appear more than once. Place
% it either in the \env{firsthead}, or in the body of the table. It
% should not be the \emph{first} command in any entry.
%
% \section{Multicolumn entries}
%
% The "\multicolumn" command may be used in \env{longtable} in exactly
% the same way as for \env{tabular}. So you may want to skip this
% section, which is rather technical, however coping with "\multicolumn"
% is one of the main problems for an environment such as
% \env{longtable}. The main effect that a user will see is that
% certain combinations of "\multicolumn" entries will result in a
% document needing more runs of \LaTeX\ before the various `chunks' of
% a table align.
%
% The examples in this section are set with "LTchunksize" set to the
% minimum value of one, to demonstrate the effects when "\multicolumn"
% entries occur in different chunks.
%
% \begin{table}[!htp]
% \begin{center}

%  \addtocounter{LT@tables}{-1}
%  \begin{longtable}{|c|c|c|}
%  \caption{A difficult {\cs{multicolumn}} combination:
%                                pass #1\label{pass#1}}\\

%    1&2&3\\
%    \multicolumn{3}{|c|}{wide multicolumn spanning 1--3}\\

%

%
% \ltexample{3}
%
% \ltexample{4}
%
% \end{center}
% \end{table}
%
% Consider Table~\ref{pass1}.
% In the second chunk, \env{longtable}  sees the wide
% multicolumn entry.  At this point it thinks that the first two
% columns are very narrow. All
% the width of the multicolumn entry is assumed to be in the
% third column. (This is a `feature' of \TeX's primitive "\halign"
% command.) \env{longtable} then passes the information that there
% is a wide third column to the later chunks, with the result that the
% first pass over the table is too wide.
%
% If the `saved row' from this first pass was re-inserted into the
% table on the next pass, the table would line up in two passes, but
% would be much two wide.
%
% \DescribeMacro{\kill}%
% The solution to this problem used in Versions 1~and~2, was to use a
% "\kill" line. If a line is "\kill"ed, by using "\kill" rather than
% "\\" at the end of the line, it is used in calculating
% column widths, but removed from the final table. Thus entering
% "\kill"ed copies of the last two rows before the wide multicolumn
% entry would  mean that "\halign" `saw' the wide entries in the first
% two columns, and so would not widen the third column by so much to
% make room for the multicolumn entry.
%
% In Version~3, a new solution was introduced. If the saved row in
% the ".aux" file was not being used, \env{longtable} used a special
% `draft' form of "\multicolumn", this modified the definition, so the
% spanning entry was never considered to be wider than the columns it
% spanned. So after the first pass, the ".aux" file stored the
% widest normal entry for each column, no column was widened due to
% "\span"ned columns. By default \env{longtable} ignored the ".aux"
% file, and so each run of \LaTeX\ was considered a first pass. Once the
% "\setlongtables" declaration was given, the saved row in the ".aux"
% file, and the proper definition of "\multicolumn" were used. If any
% "\multicolumn" entry caused one of the columns to be widened, this
% information could not be passed back to earlier chunks, and so the
% table would not correctly line up until the third pass. This algorithm
% always converged in three passes as described above, but in examples
% such as the ones in Tables \ref{pass1}--\ref{pass4}, the final
% widths were not optimal as the width of column~2, which is
% determined by a "\multicolumn" entry was not known when the final
% width for column~3 was fixed, due to the fact that \emph{both}
% "\multicolumn" commands were switched from `draft' mode to `normal'
% mode at the same time.
%
% Version~4 alleviates the problem considerably.
% The first pass of the table will
% indeed have the third column much too wide. However, on the next pass
% \env{longtable} will notice the error and reduce the column width
% accordingly. If this has to propagate to chunks before the
% "\multicolumn" one, an additional pass will, of course, be
% needed. It is possible to construct tables where this rippling up of
% the correct widths takes several passes to `converge' and produce a
% table with all chunks aligned. However in
% order to need many passes one needs to construct a table with
% many overlapping "\multicolumn" entries, all being wider than the
% natural widths of the columns they span, and all occurring in
% different chunks. In the typical case the algorithm will converge
% after three or four passes, and, the benefits of not needing to edit
% the document before the final run to add "\setlongtables", and the
% better choice of final column widths in the case of multiple
% "\multicolumn" entries  will hopefully more than pay for the extra
% passes that may possibly be needed.
%
% So Table~\ref{pass1} converges after 4~passes, as seen in
% Table~\ref{pass4}.
%
% You can still speed the convergence by introducing judicious "\kill"
% lines, if you happen to have constellations like the above.
%
% If you object even to \LaTeX-ing a file twice, you should
% make the first line of
% every \env{longtable} a "\kill" line that contains the widest entry
% to be used in each column. All chunks will then line up on the first
% pass.
%
% \section{Adjustment}
%
% The optional argument of \env{longtable} controls the
% horizontal alignment of the table. The possible options are "[c]",
% "[r]" and "[l]", for  centring,
% right  and left adjustment, respectively.
% \DescribeMacro{\LTleft}
% Normally centring is the default, but this document specifies
% \DescribeMacro{\LTright}
%\begin{verbatim}
% \setlength\LTleft\parindent
% \setlength\LTright\fill
%\end{verbatim}
% in the preamble,
%  which means that the tables are set flush left, but
% indented by the usual paragraph indentation. Any lengths can be
% specified for these two parameters, but at least one of them should be
% a rubber length so that it fills up the width of the page, unless
% rubber lengths are added between the columns using the
% "\extracolsep" command.
% For instance
%\begin{verbatim}
%  \begin{tabular*}{\textwidth}{@{\extracolsep{...}}...}
%\end{verbatim}
% produces a full width table, to get a similar effect with
% \env{longtable} specify
%\begin{verbatim}
% \setlength\LTleft{0pt}
% \setlength\LTright{0pt}
% \begin{longtable}{@{\extracolsep{...}}...}
%\end{verbatim}
%
% \section{Changes}
%
% This section highlights the major changes since version~2. A more
% detailed change log may be produced at the end of the code listing
% if the "ltxdoc.cfg" file specifies
%\begin{verbatim}
%  \AtBeginDocument{\RecordChanges}
%  \AtEndDocument{\PrintChanges}
%\end{verbatim}
%
% Changes made between versions 2 and 3.
% \begin{itemize}
% \item The mechanism for adding the head and foot of the table has been
% completely rewritten. With this new mechanism, \env{longtable} does
% not need to issue a "\clearpage" at the start of the table, and so the
% table may start half way down a page. Also the "\endlastfoot" command
% which could not safely be implemented under the old scheme, has been
% added.
% \item \env{longtable} now issues an error if started in the scope of
% "\twocolumn", or the \env{multicols} environment.
% \item The separate documentation file "longtable.tex" has been
% merged with the package file, "longtable.dtx" using Mittelbach's
% \package{doc} package.
% \item Support for footnotes has been added. Note however that
% "\footnote" will not work in the `head' or `foot' sections of the
% table. In order to put a footnote in those sections (e.g., inside a
% caption), use "\footnotemark" at that point, and "\footnotetext"
% anywhere in the table \emph{body} that will fall on the same page.
% \item The treatment of "\multicolumn" has changed, making
% "\kill" lines unnecessary, at the price of sometimes requiring a
% third pass through \LaTeX.
% \item The "\newpage" command now works inside a \env{longtable}.
% \end{itemize}
%
% Changes made between versions 3 and 4.
% \begin{itemize}
% \item A new algorithm is used for aligning chunks. As well as the
% widest width in each column, \package{longtable} remembers which
% chunk produced this maximum. This allows it to check that the
% maximum is still achieved in later runs. As \package{longtable} can
% now deal with columns shrinking as the file is edited, the
% "\setlongtables" system is no longer needed and is disabled.
%
% \item An extra benefit of the new algorithm's ability to deal with
% `shrinking' columns is that it can give better (narrower) column
% widths in the case of overlapping "\multicolumn" entries in
% different chunks than the previous algorithm produced.
%
% \item The `draft' multicolumn system has been removed, along with
% related commands such as "\LTmulticolumn".
%
% \item The disadvantage of the new algorithm is that it can take more
% passes. The theoretical maximum is approximately twice the length
% of a `chain' of columns with overlapping "\multicolumn" entries,
% although in practice it usually converges as fast as the old
% version. (Which always converged in three passes once
% "\setlongtables" was  activated.)
%

% Previous releases left the "\lineskip" glue at the end of each chunk

% "\lineskip" glue at the top of a box. This meant that normally the

% chunk boundary came before the first row of the next chunk
% but after the lineskip glue at the end of this chunk. This is the
% wrong place, e.g., it means even a "\penalty10000" does not stop a
% break as the "\lineskip" glue in the previous item on the list
% provides a legal breakpoint. So now remove the "\lineskip" glue that
% was before the dummy row and introduce "\LT@setprevdepth" to set the
