Un tableau n'�tant qu'un ensemble de cellules, il est naturel de les construire � partir de
ces derni�res. Le premier est r�alis� de la mani�re la plus �l�mentaire qui soit : de simples
cellules encadr�es, toutes de la m�me taille et align�es � gauche. Le r�sultat est
rudimentaire mais tr�s rapide � obtenir.
<br>
<br>
Le deuxi�me tableau apporte quelques am�liorations : chaque colonne a sa propre largeur, les
titres sont centr�s et les nombres cadr�s � droite. De plus, les traits horizontaux ont �t�
enlev�s. Ceci est r�alis� gr�ce au param�tre <code>border</code> de la m�thode <a href='../doc/cell.htm'>Cell()</a>, qui
permet de sp�cifier quels bords de la cellule doivent �tre trac�s. Dans le cas pr�sent, on
d�sire les bords gauches (<code>L</code>) et droits (<code>R</code>). Reste le probl�me du trait
horizontal final pour refermer le tableau. Il y a deux possibilit�s : soit tester dans la
boucle si on se trouve sur la derni�re ligne, auquel cas on utilise <code>LRB</code> pour le
param�tre <code>border</code> ; soit, comme c'est fait ici, ajouter le trait une fois la boucle
termin�e.
<br>
<br>
Le troisi�me tableau est semblable au deuxi�me mais utilise des couleurs. Il suffit pour cela
de pr�ciser les couleurs de fond, de texte et de trait souhait�es. L'alternance de couleur
pour les lignes est obtenue en utilisant des cellules � fond alternativement color� et
transparent.
