Graphics, Figures & Tables ⇒ A better table ?

[Cham]

How can I add an extra vertical space below the first line, just before the data ? \vspace doesn't work.

Guys, I still need some help.

For the moment, I can't decide between these three table styles :

Code: Select all

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

\usepackage{xcolor}
\usepackage{colortbl}

The first one is perfect, but it's dull to look at. The third table is very nice too, but there are some white vertical lines in the first row, and I would prefer to remove them (how ?), I would also like to raise a bit the spacing between each line in this case.

Any suggestion ?
