+% threeparttable.sty (or 3parttable) (or 3parttab on DOS)
+% by Donald Arseneau Updated on June 13, 2003.
+% Three part tables: title, tabular environment, notes
+%
+% This file may be distributed, modified, and used in other works with just
+% one restriction: modified versions must clearly indicate the modification
+% (a name change, or a displayed message, or ?).
+%
+% This package facilitates tables with titles (captions) and notes. The
+% title and notes are given a width equal to the body of the table (a
+% tabular environment). By itself, a threeparttable does not float, but
+% you can put it in a {table} or a {table*} or some other environment.
+% (This causes extra typing, but gives more flexibility.)
+%
+% Inside a threeparttable there should be a caption, followed by a tabular
+% environment (tabular, tabular* or tabularx), possibly followed by a series
+% of itemized "tablenotes". The caption can also go after the tabular.
+%
+% \begin{table}
+% \begin{threeparttable}[b]
+% \caption{...}
+% \begin{tabular}...% or {tabular*}
+% ...42\tnote{1}&....
+% ...
+% \end{tabular}
+% \begin{tablenotes}
+% \item [1] the first note
+% ...
+% \end{tablenotes}
+% \end{threeparttable}
+% \end{table}
+%
+% The {threeparttable} environment takes an optional vertical-placement
+% parameter, [t], [b], or [c]; the default is [t].
+%
+% At present, there is nothing automatic about the notes; you must specify the
+% identifier in the body of the table ("\tnote{a}") and in the notes below
+% ("\item[a]..."). I chose this method because automatic numbering with
+% \footnote would be very hard to use, particularly because many tables make
+% repeated reference to a single note. If someone has a convenient, elegant,
+% automatic system, I'll listen! \tnote commands can be given in the caption
+% too, and they will *NOT* appear in the list of tables.
+%
+% There are several commands which should be redefined for customizing the
+% behavior of threeparttable, especially the table notes. Some options
+% are provided for common variations of the table notes.
+%
+% Options:
+% [para] Notes come one-after-another without line breaks
+% [flushleft] No hanging indentation on notes
+% [online] \item tag is printed normal size, not superscript
+% [normal] restores default formatting
+%
+% These options can be given to the \usepackage command or to each individual
+% {tablenotes} environment. The [normal] option is intended to reverse the
+% whole-document options for a particular table; e.g.
+%
+% \usepackage[para]{threeparttable}
+% ... much document ...
+% \begin{tablenotes}[normal,flushleft]
+%
+% These few options are unlikely to give you a desired specified format,
+% so you should expect to redefine one or more of the configuration
+% commands. Note that mixing options with redefinitions is unlikely
+% to work smoothly. Please submit your redefinitions to be used as
+% options in future versions!
+%
+% Configuration commands:
+% \TPTminimum: command telling minimum caption width. Default "4em";
+% change with \def or \renewcommnd.
+% \TPTrlap: A command with one argument, to make notes go out of
+% the column, into the column separation (for right-aligning)
+% \TPTtagStyle: Command with one argument to set appearance of the tag
+% (number) in \tnote{tag}. It defaults to nil. It could be \textit.
+% \tnote: Yes, you can redefine the \tnote command.
+% \TPTnoteLabel: Command with one argument to format the item label in
+% the tablenotes list (\makelabel); default uses \tnote.
+% \TPTnoteSettings: A command to issue all the list-environment setup
+% commands for the tablenotes.
+% \tablenotes or \TPTdoTablenotes: Yes, you can redefine the whole
+% tablenotes environment. (\tablenotes processes optional
+% parameters, then invokes \TPTdoTablenotes; the [para] option
+% replaces \TPTdoTablenotes.)
+%
+% For figures, there is an equivalent "measuredfigure" environment. It
+% is fairly fragile though, and should be used only for a single graphic
+% above a single caption.
+%
+% Note that the \caption formatting is *not* adjusted by threeparttable.
+% You should use one of the caption-control packages to get captions
+% that work well as table titles. In truth, threeparttable sets
+% \abovecaptionskip to zero for captions above the table, but more
+% complete changes are called for.

+
+Notes:
+
+May 15, 2001: changed hook-in to use \setbox in a wrapper macro (or
+explicit width of tabular*). I don't remember why I used \everyhbox
+and \lastbox before. Something may break now. At least it works with
+tabularx.
+
+June 13, 2003: Re-wrote a lot, particularly the hook mechanism. Use macros
+and package/environment options for formatting control. Add measuredfigure.
