Hello Anas,

Unfortunately, LaTeX typesets tabular material rigidly from left to 
right, and the bidirectional primitives provided by eTeX have no effect 
here. There could be some way, which I have not investigated, to work 
around this limitation at the macro level (suggestions are welcome!), 
but I do think that it would be better to solve this problem at the 
level of the typesetting engine :-)

One workaround, which I used when I typeset my thesis with ArabTeX, is 
to wrap the content of each cell with \RL{...} and to use some macro in 
your favorite editor (or an external script) to flip the rows of your 
tables from
A & B & C & D \\
D & C & B & A \\
