<p class='demo'><a href='tuto4.php' target='_blank' class='demo'>[Démo]</a></p>
La méthode-clé utilisée est <a href='../doc/acceptpagebreak.htm'>AcceptPageBreak()</a>. Elle permet d'accepter ou non un saut de
page automatique. En refusant le saut et en modifiant la marge gauche (par <a href='../doc/setleftmargin.htm'>SetLeftMargin()</a>),
on obtient le formatage en colonnes.
<br>
Pour le reste, peu de changements ; deux propriétés ont été ajoutées à la classe pour mémoriser
le numéro de colonne courant ainsi que l'ordonnée du début des colonnes, et l'appel à MultiCell()
spécifie que le texte a 6 cm de largeur.
