\subsection{Definition of \tkzcname{tkzTabSetup}}

The simplest way is the macro \tkzcname{tkzTabSetup}, which changes the main styles.

\noindent\emph{Use this macro at the beginning, before the table. Line widths are usually given in \tkzname{pt}; the default value is the most common one. Each call resets to their default values the keys that are not given.}

\subsection{Changing the styles with \tkzcname{tikzset}}

Here is the list of the styles used and their definitions.

\begin{tabular}{ll}
\toprule
\tkzname{node style} & style of the nodes used for the values placed in the table  \\
\tkzname{low left} &  value at the bottom left of a vertical rule  \\
\tkzname{low right} & value at the bottom right of a vertical rule\\
\tkzname{high left} & value at the top left of a vertical rule\\
\tkzname{high right}& value at the top right of a vertical rule\\
\tkzname{low} & value at the bottom of a vertical rule \\
\tkzname{high} & value at the top of a vertical rule \\
\tkzname{on double} & background color under a double bar \\
\tkzname{tan style} & style of a tangent\\
\tkzname{arrow style} & style of the arrows of variation\\
\tkzname{from style} & style of the line from a value to its image\\
\tkzname{h style} & style of a forbidden zone\\
\tkzname{double style} & style of a double bar\\
\tkzname{t style} & style of a vertical rule\\
\bottomrule
\end{tabular}


The default values are:
\begin{tkzexample}[code only, small]
\def\tkzTabDefaultWritingColor{black}
\def\tkzTabDefaultBackgroundColor{white}
\def\tkzTabDefaultLineWidth{0.4pt}
\def\tkzTabDefaultArrowStyle{latex'}
\def\tkzTabDefaultSep{2pt}
\end{tkzexample}

The main default styles are:

\begin{tkzexample}[code only, small]
\tikzset{node style/.style  = {inner sep   =  \tkzTabDefaultSep,
                               outer sep   =  \tkzTabDefaultSep,
                               fill        =  \tkzTabDefaultBackgroundColor}}
\tikzset{tan style/.style   = {>           =  \tkzTabDefaultArrowStyle,
                               ->,
                               color       =  \tkzTabDefaultWritingColor}}
\tikzset{arrow style/.style = {\tkzTabDefaultWritingColor,
                               ->,
                               >            = \tkzTabDefaultArrowStyle,
                               shorten >    = \tkzTabDefaultSep,
                               shorten <    = \tkzTabDefaultSep}}
\tikzset{from style/.style   = {shorten >   = \tkzTabDefaultSep,
                                shorten <   = \tkzTabDefaultSep,
                                line width  = \tkzTabDefaultLineWidth,
                                >           = \tkzTabDefaultArrowStyle,
                                ->,
                                draw        = \tkzTabDefaultWritingColor,
                                dotted}}
\tikzset{t style/.style = {style  = dotted,
                           draw   = \tkzTabDefaultWritingColor}}
\tikzset{h style/.style = {pattern       = north west lines,
                           pattern color = \tkzTabDefaultWritingColor}}
\tikzset{on double/.style   = {fill      =  \tkzTabDefaultBackgroundColor}}
\tikzset{double style/.append style = {%
         draw            = \tkzTabDefaultWritingColor,
         double          =  \tkzTabDefaultBackgroundColor}}
\end{tkzexample}

The background colors of the different parts of the table are defined by the styles:
\begin{tkzexample}[code only, small]
\tikzset{fondC/.style={fill = \tkzTabDefaultBackgroundColor}}
\tikzset{fondL/.style={fill = \tkzTabDefaultBackgroundColor}}
\tikzset{fondT/.style={fill = \tkzTabDefaultBackgroundColor}}
\tikzset{fondV/.style={fill = \tkzTabDefaultBackgroundColor}}
\end{tkzexample}
Finally, the positions of the values with respect to the arrows are:
\begin{tkzexample}[code only, small]
\tikzset{low left/.style    = {above left  =  \tkzTabDefaultSep}}
\tikzset{low right/.style   = {above right =  \tkzTabDefaultSep}}
\tikzset{high right/.style  = {below right =  \tkzTabDefaultSep}}
\tikzset{high left/.style   = {below left  =  \tkzTabDefaultSep}}
\tikzset{low/.style         = {above       =  \tkzTabDefaultSep}}
\tikzset{high/.style        = {below       =  \tkzTabDefaultSep}}
\end{tkzexample}

    {$0$,$1$,$2$,$3$}%
  \tkzTabLine{z,+,d,h,d,-,t}

\end{tkzexample}

	\end{tikzpicture}
	\end{tkzexample}
\end{center}


\subsubsection{Using \tkzcname{tikzset} and \tkzcname{tkzTabSetup}}

 Note the last \tkzcname{tkzTabSetup}, which resets the default values.
