You do even better with those \newline s replaced by  \\&
to give more rows, rather than forcing very large cells.

Or use something like my suggestions below.

You can implement a counter this way:

\newcounter{itemcount}
\renewcommand{\theitemcount}{\arabic{itemcount}. }
\newcommand{\myitem}[2][\\&]{#1%
  \stepcounter{itemcount}\textbf{\theitemcount#2} }

  ... where the optional argument '\\&' means that entries
create new rows and cells automatically; e.g. starting with

  \myitem{D\'efinition} ...

but when you don't want the new row use:

   &\myitem[]{G\'en\'eralit\'es} ...


You can even give yourself shorthands, as follows:

\newcommand{\newrow}{\\&}
\newcommand{\Exer}[1][\newrow]{\myitem[#1]{Exercice}}
\newcommand{\Defn}[1][\newrow]{\myitem[#1]{D\'efinition}}
\newcommand{\Gener}[1][\newrow]{\myitem[#1]{G\'en\'eralit\'es}}


Now these are used like:

   ... &\Gener[] .....
   \Exer ....
   \Exer ....
   \Defn ....
etc.


Hope this helps,

	Ross
