\chapter{Table Layout}

\begin{sl}
This example shows floats in one-column document.

\emph{Common float settings.}\\
Font for float contents \verb|\small|; skips before foot material half reduced;
footnote rule has maximum width${{}\approx27}$\,mm; separation between
beside caption and object equals to 1\,em; separation between beside float
boxes also equals to 1\,em.
\begin{verbatim}
\usepackage[font=small,footskip=.5\skip\footins,
   captionskip=5pt,capbesidesep=quad,floatrowsep=quad]{floatrow}
\end{verbatim}

\emph{Common caption settings.}\\
For caption text used \verb|\small| font;
justification \texttt{centerlast} (last line centered).
\begin{verbatim}
\usepackage[font=small,justification=centerlast]{caption}
\end{verbatim}

\emph{Common subcaption settings.}\\
Justification centerlast (last line centered).
\begin{verbatim}
\usepackage[justification=centerlast]{subfig}
\end{verbatim}

\emph{Special settings for float types.}

\emph{Table.}\\
For tables is used \texttt{Plaintop} style (captions aligned by top line);
skip between caption and object  half reduced.
\begin{verbatim}
\floatsetup[table]{style=Plaintop,captionskip=5pt}
\end{verbatim}

\emph{Special caption settings for float types.}

\emph{Table.}\\
For tables was created special format with separated label flushed to the right;
font of label slanted, font of caption text bold.

To restore normal behavior for \verb|\floatfoot| macro, here goes \verb|\captionsetup|
for \texttt{floatfoot} style.
\begin{verbatim}
\DeclareCaptionFormat{flushrightlabel}{\leavevmode
  \rightline{#1}#2#3\par}

\captionsetup[table]%
   {format=flushrightlabel,labelsep=newline,
    textfont=bf,labelfont=sl}

\captionsetup[floatfoot]{format=default}
\end{verbatim}
With caption's version 3d you may set table format by this way:
\begin{verbatim}
\DeclareCaptionFormat*{flushrightlabel}{\rightline{#1}#3\par}

\captionsetup[table]%
   {format=flushrightlabel,labelsep=none,textfont=bf,labelfont=sl}
\end{verbatim}
You may see, that there are absent settings for \verb|\floatfoot|.
(Unfortunately, if your table has only label, and no any text, the unwanted
space appears instead of caption title.)

For continued table (like table~\ref{rot:tab:cont} on the page~\pageref{rot:tab:cont})
was created new label format and defined command \verb|\ContinuedTable|, which includes
special \texttt{continued} format and \verb|\ContinuedFloat| command.
\begin{verbatim}
\DeclareCaptionLabelFormat{continued}{\bothIfFirst{#1}{ }#2.
  \emph{Continued}}

\def\ContinuedTable{\ContinuedFloat
  \captionsetup[table]{labelformat=continued}}
\end{verbatim}

\emph{Special settings for special float layout.}

\emph{Rotated.}\\
For rotated floats beside caption placed to right side of object;
right side expanded to the top of running head. To delete running head from pages
with rotated float was used \verb|\emptyfloatpage| macro\footnote{In current example the
\protect\com{wideemptyfloatpage} command is the synonym.} and
loaded \pkg{floatpagestyle} package.
\begin{verbatim}
\DeclareMarginSet{expand}%
   {\setfloatmargins{\hfil}
                   {\hskip-\headsep\hskip-.7\headheight plus1fil}}
\floatsetup[rotfloat]{sidecappos=right,floatmargins=expand}
\end{verbatim}

The example of subtables (table~\ref{floatbox:wide:subtab}) with two
subtables~\subref{subtab:A} and~\subref{subtab:B}.

Here for sub tables was used the \env{subfloatrow} environment (this environment
allows usage (and definition) of common horizontal skip between subfloats).
\begin{verbatim}
\begin{table*}\extrarowheight1pt
\floatbox[\captop]{table}[\FBwidth]
{\caption{...}
{\begin{subfloatrow}
\subfloat[...]{...}

\subfloat[...]{...}%
