+% \begin{abstract}
+% This package allows to typeset tables of specified width, provided they fit in one
+% page. Instead of introducing an infinite stretching glue, which has an
+% unsymmetrical effect in standard \LaTeX, here the |\tabcolsep| dimension is
+% computed so as to have the table come out with the proper width.
+% \end{abstract}
+%
+%\section{Introduction}
+% It is well known that when the standard environment |tabular*| is opened with
+% a specified width, it is necessary to introduce in the delimiter declaration |@{...}|
+% of (possibly) the first cell of the model row a declaration such as
+% \begin{verbatim}
+% \extraclosep{\fill}
+% \end{verbatim}
+% in addition to other possible printable delimiters, such as vertical lines, and
+% other fixed spacing commands. The effect is that the extra stretchable glue
+% operates only on the left of each cell \emph{after} (to the \emph{right} of)
+% the cell that received the declaration; the first cell will never get larger
+% in spite of the presence of this glue.
+%
+% Another package, |tabularX|, normally distributed by the \LaTeX\,3 Team with
+% every version of the \TeX\ system distribution, allows to create expandable cells,
+% provided they contain only text. These expandable cells are identified with the
+% column identifier |X|; this identifier defines a paragraph-like cell, the width of
+% which gets determined after some runs of the typesetter on the same source
+% tabular material, so as to find out the correct width of the textual columns.
+%
+% The approach here is a little bit different: the cell contents need not be textual
+% and no cell width is determined in one or more runs of the typesetter; instead the
+% inter column glue is determined so as to fill every cell on both sides with the
+% proper space. The macros contained in this package are insensitive to the
+% particular kind of cell descriptors and to the presence of multiple |\multicolumn|
+% commands. It proved to work properly also if the |array| package extensions are
+% used.
+%
+% On the other hand, as well as for |tabularX|, it needs to typeset the table three
+% times; the first two times with standard values for the inter column glue
+% |\tabcolsep|, in order to find the exact parameters of the linear dependence of
+% the table width from the value of that glue; then executes some computations
+% so as to extrapolate the final correct value of |\tabcolsep|, and on the third run
+% it eventually typesets the table with the specified width.
+%
+% The time increase needed for these three table typesettings are in general rather
+% negligible, nevertheless if a specific document contained many dozens of such
+% tables, the compilation time might become observable.
+%
+% It might be noticed that in order to perform the necessary computations a
+% fractional division algorithm had to be implemented; A specific \LaTeX\ run that
+% loads several different packages might then contain several fractional division
+% macros, besides those already contained in the kernel. But unfortunately each of
+% these macros has been designed for a specific purpose and a specific interface.
+%
+% \section{Usage}
+% This package issues an error message only in case the environment includes
+% other unhided environment; this is explained in the Implementation section.
+% Here it is assumed that the table is first typeset to its
+% natural width; should it appear too small, and should it be typeset at a larger
+% width, for example by filling the total |\linewidth| available at that specific
+% point, then and only then the |tabular| environment is changed to |widetable|,
+% Should the initial table be moderately larger than the |\linewidth|, than it might
+% be shrinked to |\linewidth| with |widetable|, provided there are enough
+% columns, and therefore delimiters, to be reduced in size. Of course it's impossible
+% to typeset any table with any negative value of |\tabcolsep|; or better, it is
+% possible, but the result in general is very messy.
+%
+% In other words |widetable| should be used as a second resort, so as to correct
+% some typesetting features not considered aesthetically acceptable.
+%
+% The syntax for the use of the environment |widetable| is the same as that of the
+% |tabular*| environment; the only difference is the name. Therefore one has to
+% specify:
+% \begin{flushleft}\obeylines%
+% \cs{begin}\texttt{\{widetable\}\{}\meta{width}\texttt{\}\{}\meta{column descriptors}\texttt{\}}
+% \meta{line of cells}\texttt{\cs{\textbackslash}}
+% \meta{line of cells}\texttt{\cs{\textbackslash}}
+% \texttt{...}
+% \meta{line of cells}\texttt{\cs{\textbackslash}}
+% \meta{line of cells}\texttt{\cs{\textbackslash}}
+% \cs{end}\texttt{\{widetable\}}
+% \end{flushleft}
+%
+% \section{The method}
+% The principle on which this little package is based is the following; suppose a
+% certain table is typeset with an inter column glue $t_0=0$ and that its width
+% turns out to be $l_0$; suppose the same tabular material is typeset again with an
+% inter column glue $t_1 >0$ so that the table table gets as large as $l_1>l_0$.
+% Then, if the table has to be as wide as $l$ the inter column glue must equal the
+% value
+% \[
+% t = \frac{l - l_0}{l_1 - l_0}\cdot t_1
+% \]
+% Therefore we need to run the typesetting of the same tabular material with the
+% two values of the inter column glue set to zero and to $t_1$, respectively, so as
+% to find the widths $l_0$ and $l_1$. Afterwards it has to determine the correct
+% final value $t$, and typeset once again the same tabular material for the last
+% time.
+% Of course the first two runs must put their results into suitable boxes so as to
+% avoid outputting them into the output file, while at the same time allowing
+% to record the width of the enclosing boxes.
+%
+% \section{The long division algorithm}
+% The only simple equation the algorithm must compute consists in evaluating the
+% difference of of two lengths (a computation that is perfectly feasible with the
+% available simple \TeX\ primitive commands); a fractional division (not feasible
+% with any \TeX\ primitive command), and finally into multiplying this division
+% result by the only non zero inter column glue (another simple task to be done
+% with \TeX\ primitive commands).
+%
+% I have tried several algorithms for computing the fractional result of the division
+% of two lengths; unfortunately no one guarantees a minimum of precision with
+% any sized operands; overflows and similar ``accidents'' are very common.
+% Iterative algorithms are difficult to initialize; scaling the operands give a good
+% % chance of getting acceptable results, but in one way or another I always found
+% some drawbacks.
+% Therefore I decided to program the so called ``long division'' algorithm
+% preceded by a number of tests in order to avoid spending time in vanishing
+% results, and, even more important, to waste time in getting overflows that cause
+% an abnormal termination of the typesetting program.
+%
+% Of course there is no limit to a better solution; nevertheless the one I
+% implemented never crashed in any real world situation I tested.
+%
+% \section{Acknowledgements}
+% I must deeply thank Enrico Gregorio for the revision of this package macros and
+% for his wise suggestions about the correct programming style. If some glitch still
+% remains in the programming style, that is just my fault.
+% \StopEventually{}
+%
+% \section{Implementation}
+% the first thing to do is to globally define a certain number of \TeX\ dimensions
+% and counters; these dimension and counter registers are selected among the
+% first even numbered ones, as our Grand Wizard suggested in the \TeX\-book.
+%
+% Actually I'd prefer to define such registers within the group of the division
+% algorithm, so as not to mess up anything that might be used by other macros,
+% but I accepted the suggestion of Enrico Gregorio, about the programming style
+% and I left these register definitions in a global position, instead of a local group
+% position.
+%
+% Another point that initially I had solved in a different way was to use register
+% numbers over the value 255, the maximum that good old \TeX\ could handle.
+% Now the typesetting\slash interpreter program \textsf{pdftex} embeds all the
+% extensions introduced with the former \textsf{$\varepsilon$-\TeX} program;
+% now the numbering of the registers can go up to $2^{15}-1$, and there is
+% enough choice for any numbering. But it may be argued that \LaTeX\ users do
+% not upgrade their software so often, while there are some situations where the
+% use of obsolete versions must be still preferred (I can't imagine any, but they
+% assure me that there are some). Therefore Enrico correctly suggests to use the
+% scratch even numbered registers (Knuth's suggestion, although Knuth excluded
+% the counter registers from this statement, being the first 10 counters reserved
+% for complicated page numbering applications).
+% \begin{macrocode}
+\dimendef\wt@Numer=2
+\dimendef\wt@Denom=4
+\countdef\wt@Num=2
+\countdef\wt@Den=4
+\countdef\wt@I=6
+\def\wt@segno{}
+% \end{macrocode}
+%
+% We then start the definition of the division algorithm; the name of the macro and
+% the separators of the delimited arguments are in Italian, thus minimizing the risk
+% of colliding with macros of other packages. ``dividi\dots per\dots in\dots''
+% means ``divide\dots by\dots, to\dots''; the first ``\dots'' represent the
+% dividend, the second ``dots'' represent the divisor (both are lengths), while the
+% third ``\dots'' represent the quotient (a signed fractional decimal number).
+%
+% The first operations performed on the operands are to copy them into named
+% dimension registers; the named registers make the programming a little easier,
+% in the sense that the chosen names have a meaning and their contents should
+% conform to that meaning.
+%
+% Then the sings of the register operands are checked and pssibly changed so as to
+% work with positive values; the overall result sign is memorized into a named
+% macro (all macros are named, but here the name conforms to its contents
+% ``segno'' maps to ``sign'').
+% Afterwards the zero value of the denominator is tested; if the test is true the
+% result assigned to the internal quotient macro |\wt@Q| is the signed dimensional
+% ``infiniy'', that in \TeX\ and \LaTeX\ is equal to $2^{30}-1$ scaled points; this
+% value is assigned by the format to the kernel dimension register |\maxdimen|, so
+% we need just use this name, instead of assigning strange numerical values; the
+% only thing we must pay attention to is to strip the ``pt'' information from this
+% ``infinite'' dimension, since the quotient must be a dimensionless signed
+% fractional decimal number.
+%
+% Otherwise we load the operands in similarly named counter registers, effectively
+% transferring the dimension integer number of scaled points to integer variables
+% over which we continue our operations.
+%
+% We compute by the primitive \TeX\ integer division command the integer part of
+% the quotient and we assing its expanded decimal value, followed by a decimal
+% point, to the temporary internal quotient. Getting back to dimensions,
+% we compute the remainder of the numerator minus the quotient times the
+% denominator in terms of lengths. We locally set the number of iterations |\wt@I|
+% to six, and then we call the iterative algorithm of the long division within a
+% |\@whilenum|\dots|\do| cycle.
+%
+% At the exit of this cycle the internal quotient |\wt@Q| contains all the digits of the
+% integer and the fractional part of the result.
+%
+% Now comes the interesting part: we are within a group and we must ``throw''
+% the quotient outside the group, but hopefully we would not like to leave
+% something behind; we then define an expanded macro that contains the
+% unexpanded |\endgroup| so that when we execute that macro, it is this very
+% action that closes the group and at the same time, in spite of having been started
+% within it,
+% it keeps being executed bringing outside the definition of the external quotient
+% that will be executed outside the group with the expanded value of the
+% internal quotient. When |\x| is finished it does not exist any more as well as any
+% value that was assigned or defined within the group.
+% \begin{macrocode}
+\def\dividi#1\per#2\in#3{%
+ \begingroup
+ \wt@Numer #1\relax \wt@Denom #2\relax
+ \ifdim\wt@Denom<\z@ \wt@Denom -\wt@Denom \wt@Numer -\wt@Numer\fi
+ \ifdim\wt@Numer<\z@ \def\wt@segno{-}\wt@Numer -\wt@Numer\fi
+ \ifdim\wt@Denom=\z@
+ \edef\wt@Q{\ifdim\wt@Numer<\z@-\fi\strip@pt\maxdimen}%
+ \else
+ \wt@Num=\wt@Numer \wt@Den=\wt@Denom \divide\wt@Num\wt@Den
+ \edef\wt@Q{\number\wt@Num.}%
+ \advance\wt@Numer -\wt@Q\wt@Denom \wt@I=6

+ \fi
+ \edef\x{\noexpand\endgroup\noexpand\def\noexpand#3{\wt@segno\wt@Q}}
+ \x
+}
+% \end{macrocode}
+%
+% The cycle for the long division consists in multiplying the remainder in
+% |\wt@Numer| by ten, then reassigning the dimension value to the numerator
+% integer counter so as to determine a new digit of the quotient in |\wt@q|. After
+% this, this digit is appended by means of an expanded definition of the internal
+% quotient, but it is used also for determining the new remainder in the
+% |\wt@Numer| dimension register. Since the iteration is performed six times, six
+% fractional digits are determined by this procedure, probably one digit too many,
+% but its better one too many than the opposite.
+% \begin{macrocode}
+\def\wt@dividiDec{%
+ \wt@Numer=10\wt@Numer \wt@Num=\wt@Numer \divide\wt@Num\wt@Den
+ \edef\wt@q{\number\wt@Num}\edef\wt@Q{\wt@Q\wt@q}%
+ \advance\wt@Numer -\wt@q\wt@Denom}
+% \end{macrocode}
+%
+% Now we define the dimension register that is to contain the desired table width.
+% We further define the start of the tabular typesetting that will be useful in a while.
+% Actually the table preamble is being saved into a macro, so that when the
+% \meta{width} and the \meta{column descriptors} are given to the opening
+% environment statement, these saved quantities can be used again and again.
+%
+% \begin{macrocode}
+\newdimen\wt@width
+\def\wt@starttabular{\expandafter\tabular\expandafter{\wt@preamble}}
+% \end{macrocode}
+%
+% The environment opening as well as the environment closing are defined by
+% means of low level commands. Due to the syntax of the opening command that
+% requires two compulsory arguments, these are saved in the recently defined
+% dimension register and to a macro respectively; anotehr macro |\wt@getTable| is
+% used to get the body of the table; the |\end{widetable}| statement
+% represents the ending delimiter of the table contents.
+%
+% \begin{macrocode}
+\def\widetable#1#2{%
+ \def\@tempC{widetable}\setlength{\wt@width}{#1}%
+ \def\wt@preamble{#2}\wt@getTable}
+% \end{macrocode}
+%
+% A new boolean, |wt@scartare|, is defined; this boolean variable will be set true in
+% order to detect if the table body is is not well formed, with |\begin| and |\end|
+% statements tha don't match, and the like; actually the |widetable| environment can
+% contain other environmente, even another |widetable| environment, but the
+% external one should not be upset by the internal ones. In order to achieve this
+% result, it is necessary that any embedded environment is hidden int a group
+% delimited by a pair of matching braces.
+% \begin{macrocode}
+\newif\ifwt@scartare\wt@scartarefalse
+% \end{macrocode}
+%
+% The closing statement will acttually do the greatest part of the job. First of all if
+% the above mentioned boolean variable is true, it skips everyting and it does not
+% set any table; but if the boolean variable is false, the table body is well formed
+% and it can do the job as described in the previous sections. It first sets
+% |\tabcolsep| to zero and sets the resulting table in box zero; the lower
+% level |tabular| with the information saved into |\wt@startabular| and the body of
+% the table contained into the token register zero.
+%
+% Then it sets |\tabcolsep| to 1\,cm (arbitrarily chosen) and typesets again the table
+% into box two. The width of box zero is $l_0$ and that of box two is $l_1$; these
+% are the lengths needed by the equation that evaluates the final typesetting glue.
+% The arbitrary constant of 1\,cm is $t_1$, and the specified width $l$ is the
+% dimension saved into |\wt@width|. The subtractions are operated directly on the
+% dimension registers |\wt@width| (the numerator) and on the auxiliary register
+% |\@tempdimenb|; the |\dividi| command is executed in order to get the quotient
+% in |\@tempA|, and the final definitive value of |\tabcolsep| is eventually computed.
+% The table is finally typeset without using boxes, while the contents of box zero
+% and two are restored upon exiting the environment to any value they might have
+% contained before entering |widetable|.
+% \begin{macrocode}
+\def\endwidetable{%
+ \ifwt@scartare
+ \noindent\null
+ \else
+ \tabcolsep=\z@
+ \setbox\z@=\hbox{\wt@starttabular\the\toks@\endtabular}%
+ \tabcolsep=1cm\relax
+ \setbox\tw@=\hbox{\wt@starttabular\the\toks@\endtabular}%
+ \advance\wt@width-\wd\z@
+ \@tempdimb=\wd\tw@
+ \advance\@tempdimb-\wd\z@
+ \dividi\wt@width\per\@tempdimb\in\@tempA
+ \tabcolsep=\@tempA\tabcolsep
+ \wt@starttabular\the\toks@\endtabular
+ \fi
+ \ignorespacesafterend
+}
+% \end{macrocode}
+%
+% Of course other actions must be performed before executing the closing
+% environment statement. We need a macro |wt@finetabella| that is equivalent to
+% the ending environment statement.
+% \begin{macrocode}
+\def\wt@finetabella{\end{widetable}}%
+% \end{macrocode}
+%
+% We finally can define the all important macro that gets the table body; it requires
+% two delimited arguments: in |#1| the table body and, after the |\end| command,
+% the closing environment name will be set in |#2|. The environment name is
+% assigned to the macro |\@tempB|, which is checked against the correct name
+% |widetable| saved in the macro |\@tempC| by the opening command. If the names
+% match, then the table body is assigned to the token register zero, to be used later
+% on by the typesetting macros. But if the names don't match, then something went
+% wrong and a package message is issued to explain what happened and how the
+% program will manage the situation.
+%
+% Specifically the names may not match if a cell contained another environment and
+% its whole |\begin{...}...\end{...}| was not closed within a pair of matched
+% braces. If an enclosed environment is hidden within a group, the delimited macro
+% |\wt@getTable| will ignore such embedded environment, otherwise it will get a
+% non matching name and messy things might happen. Besides warning about this
+% fact, the body of the table, at least what has been read by the macro, will be
+% discarded and substituted with a box containing a message; therefore a table will
+% be typeset, but not the desired one. The remaining part of the body remains in
+% the input stream and might cause, presumably, strange errors, such as |&|
+% characters used outside a tabular or array environment. We must take care of this
+% so that the typesetting procedure does not crash.
+% \begin{macrocode}
+\def\wt@getTable#1\end#2{\def\@tempB{#2}%
+ \ifx\@tempB\@tempC
+ \toks@={#1}%
+ \expandafter\wt@finetabella
+ \else
+ \PackageWarning{widetable}{%
+ The table contains environment `\@tempB' %
+ \MessageBreak
+ not enclosed in braces. This is expressly forbidden!%

+ \noindent\framebox[\wt@width]{The table was not typeset because
+ it contains a visible \texttt{\char`\\end} in one or more cells.}\par
+ \expandafter\wt@finishTable
+ \fi
+}
+% \end{macrocode}
+%
+% In order to avoid a complete mess, we have to iteratively gobble the rest of the
+% input stream until a valid |\end{widetable}| is encountered; Actually the following
+% macro will do a nice job in general, but it is not infallible if the input stream is
+% really composed in a very bad way. In facts it calls itself again and again, always
+% gobbling it arguments, until a valid terminating environment name matches the
+% name |widetable|.
