I found something useful :
the ">{\PBS\centering\hspace{0pt}}p{...}"
alignment can be written as a function
using the \newcolumntype definition
(see the array package documentation).
(To summarize)
If I write in the preamble :
\usepackage{array}
\newcommand{\preserveBackslash}[1]{\let\temp=\\#1\let
\\=\temp}
\let\PBS=\preserveBackslash
\newcolumntype{x}[1]{>{\PBS\centering\hspace{0pt}}p{#
1}}
so now, for example I can just
write in the Table Special
Column Alignment :
x{3cm}
to define a 3cm centered column !
Voila.
Thank you again Herbert for your help.
Krzys.
