% 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.

Example:
Here is some paragraph before the table. Note that this table does not
float because it is not in a {table} or {table*} environment.

$\fam0 Mu(H)+HX$~\tnote{a}}

&$\beta$(H) & $80.9^\circ\tnote{b}$ & $83.2^\circ$ \\

\begin{tablenotes}

\end{threeparttable}
\end{center}
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.
