[Tex/LaTex] argument in \begin{subtable}

marginsspacingsubcaptiontables

I use \begin{subtable}{.5\textwidth}...\end{subtable} to produce two (or more) subtables side by side (from the subcaption package). But I don't understand what {.5\textwidth} means. I tried different values, it looks like it is related to the position of the subtables or the spacing between them. I tried to find the documentation for it on Google, but no luck. Where I can find it or can anyone please explain it a little for me?

We're dealing with the subcaption package.

.5\textwidth means "half of the current text width".

A proper usage of subtable should be

\begin{table}
\centering
\begin{subtable}{.5\textwidth}
\centering

<table material>

\caption{<subcaption>}
\end{subtable}% <---- don't forget this %
\begin{subtable}{.5\textwidth}
\centering

<table material>

\caption{<subcaption>}
\end{subtable}

\caption{<main caption>}
\end{table}

Notice the % after the first \end{subtable} that masks the end of line (which would give a space that will put the second subtable below the first one, as the line would be overfull).

Put caption above tables, if this accords to the style you're using or to your personal preferences.

[Tex/LaTex] How to get marginnote to use the whole margin space

You have to tell geometry also the desired width of your marginal notes. Keep also into account that there is the parameter \marginparsep that should be non zero. Therefore something like

\usepackage[top=2cm, bottom=1.3cm, left=5cm, right=0.5cm, heightrounded,
  marginparwidth=4.6cm, marginparsep=3mm]{geometry}

should be what you want (4.6+0.3=4.9, so 1mm will be kept clear at the left edge).

The option heightrounded has nothing to do with the problem at hand, but it's better to specify it so that TeX will have less problems filling pages.

You are facing two problems here:

The hvfloat package does not set \@captype (like an ordinary floating environment does) so the subcaption package has no idea if its commands are used inside a figure, a table, or not within a floating environment at all. This must be fixed by Herbert, however you could use \captionsetup{type=table} as workaround.
The standard document classes set \abovecaptionskip to a value of 10pt, \belowcaptionskip to 0pt. \abovecaptionskip will be used above the caption, and \belowcaptionskip below of it. However, this gives you a obvious problem when a \caption is typeset above a figure or table content since you will get a distance of \belowcaptionskip (=0pt) between caption and content, i.e. no distance of all. There are two different (and incompatible) ways to resolve this situation:
- \abovecaptionskip will be used between caption and content, \belowcaptionskip will be used between caption and edge of the floating environment. (This has the advantage that you could use the default values of \abovecaptionskip and \belowcaptionskip as set by the document class, and the result will not change at all when using \caption below its contents, as designed by Leslie Lamport.)
- If the caption is below its content, only \abovecaptionskip is used. If the caption is above its content, only \belowcaptionskip is used. (The skips need to be adjusted for making this work, but you are able to setup different skips for above-captions and below-captions here.)

As you see both methods have its pros and cons, but are unfortunately incompatible. However, KOMA-Script and the (sub)caption package are using the first method while hvfloat seems to use the latter. (I'm not sure about this since I didn't have found the time to look into Herbers sources, but at least hvfloat changes the values of the caption skips and therefore just loading the package will affect the skips of the non-hvfloat-floating environments (and the longtable environment and...) as well.)

To compensate this one needs to write macros to save and restore the skips.

So in total we have:

\documentclass[a4paper] {scrbook}

% Save the values of \abovecaptionskip and \belowcaptionskip into \restorecaptionskips
\edef\restorecaptionskips{%
  \noexpand\setlength\noexpand\abovecaptionskip{\the\abovecaptionskip}%
  \noexpand\setlength\noexpand\belowcaptionskip{\the\belowcaptionskip}}
%\show\restorecaptionskips
\usepackage{hvfloat}
% Save the changed values of \abovecaptionskip and \belowcaptionskip into \restorehvcaptionskips
\edef\restorehvcaptionskips{%
  \noexpand\setlength\noexpand\abovecaptionskip{\the\abovecaptionskip}%
  \noexpand\setlength\noexpand\belowcaptionskip{\the\belowcaptionskip}}
% Restore the values of \abovecaptionskip and \belowcaptionskip
\restorecaptionskips

\usepackage{subcaption}

\begin{document}

\appendix \cleardoublepage
\chapter{Some Data Tables}

\restorehvcaptionskips % only needed if "capPos=t"
\hvFloat[capPos=b,rotAngle=90,nonFloat]{table}{%
\restorecaptionskips
\captionsetup{type=table}% set \@captype
  \hspace*{\fill}
  \begin{subtable}{.3\textwidth}
    \rule{\linewidth}{12cm}
  \end{subtable}
  %
  \hspace*{\fill}
  %
  \begin{subtable}{.3\textwidth}
    \rule{\linewidth}{12cm}
  \end{subtable}
  \hspace*{\fill}
}{Table with interesting data}{}
\restorecaptionskips

\end{document}
