Graphics, Figures & Tables ⇒ Vertical Spacing in Tables

[Cham]

The table below (complete compilable code) has a small aesthetical problem with its vertical spacing. The lines are too close from each other. How can I make them "breath" ?

Code: Select all

\documentclass[12pt,letterpaper,twoside]{book}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[french]{babel}
\usepackage{amsmath}
\usepackage{tensor}
\usepackage{booktabs}
\usepackage{xcolor}
\usepackage{colortbl}

\begin{document}

\begin{table}[H]
	\centering
\begin{tabular}{cl*5{>{\centering\arraybackslash}p{1cm}}}
	\arrayrulecolor{black}
	\toprule[1.5pt]
	\toprule[.5pt]
	$\mathcal{C}$ & & $\tensor{\Omega}{_{\text\it mat}}$ & $\tensor{\Omega}{_{\text\it rad}}$ & $\tensor{\Omega}{_{\Lambda}}$ & $\tensor{a}{_*} / \tensor{a}{_0}$ & $k$ \\
	\midrule
	1 & Univers de poussières : & $1$ & $0$ & $\tfrac{3 \sqrt{3}}{2}$ & $\tfrac{1}{\sqrt{3}}$ & $1$ \\
	2 & Univers de radiation : & $0$ & $1$ & $4$ & $\tfrac{1}{\sqrt{2}}$ & $1$ \\
	3 & Univers mixte : & $\tfrac{1}{2}$ & $\tfrac{1}{2}$ & $\tfrac{27}{8}$ & $\tfrac{2}{3}$ & $1$ \\
	\bottomrule[.5pt]
	\bottomrule[1.5pt]
	\end{tabular}
	\caption{A caption}
\end{table}

\end{document}

EDIT : I added the option [4pt] after each "\\", which is almost right. The remaining problem is the spacing below the \midrule isn't the same as the [4pt] above the \bottomrule[.5pt].

You can stretch the complete table vertically by redefining the \arraystretch command.

Code: Select all

\documentclass[12pt,letterpaper,french]{book}
\usepackage[T1]{fontenc}
\usepackage{selinput}
\SelectInputMappings{
  aacute={á},
  ccedilla={ç},
  Euro={€}
}
\usepackage{babel}
\usepackage[tableposition=top]{caption}
\usepackage{mathtools}   % loads »amsmath«
\usepackage{booktabs}
\usepackage{tensor}
\usepackage[table]{xcolor}

\begin{document}
  \begin{table}[!ht]
    \renewcommand{\arraystretch}{1.3}   % <<< This is the set screw
    \caption{A caption}
    \centering
    \begin{tabular}{cl*5{>{\centering\arraybackslash}p{1cm}}}\toprule[1.5pt]\toprule[.5pt]
      $\mathcal{C}$ & & $\tensor{\Omega}{_{\text\it mat}}$ & $\tensor{\Omega}{_{\text\it rad}}$ & $\tensor{\Omega}{_{\Lambda}}$ & $\tensor{a}{_*} / \tensor{a}{_0}$ & $k$ \\ \midrule
      1 & Univers de poussières : & $1$ & $0$ & $\tfrac{3 \sqrt{3}}{2}$ & $\tfrac{1}{\sqrt{3}}$ & $1$ \\
      2 & Univers de radiation : & $0$ & $1$ & $4$ & $\tfrac{1}{\sqrt{2}}$ & $1$ \\
      3 & Univers mixte : & $\tfrac{1}{2}$ & $\tfrac{1}{2}$ & $\tfrac{27}{8}$ & $\tfrac{2}{3}$ & $1$ \\ \bottomrule[.5pt]\bottomrule[1.5pt]
    \end{tabular}
  \end{table}
\end{document}

Well, I don't understand why the spacing isn't the same above and under the table's content. See the picture below :

How can we make the table vertically symetrical ?

I can't confirm these difficulties (see attachment). Perhaps a matter of outdated packages. With the \listfiles as very first line in my example I get this this list of used files (not all up to date) from the log file.

So you might need an update.

[Cham]

I've updated my LaTeX installation to the latest version and there's no differences in the table's output. I'm still getting an asymmetrical vertical spacing. I compiled your example above, and changed that command :

\renewcommand{\arraystretch}{1.3}

to

\renewcommand{\arraystretch}{2.3}

just to see the difference. And the vertical spacing is clearly asymmetrical.
