+Il metodo principale utilizzato è <a href='../doc/acceptpagebreak.htm'>AcceptPageBreak()</a>. Permette di accettare o no un'interruzione automatica di␍
+pagina. Rifiutandolo e alterando il margine alla posizione corrrente, si raggiunge il layout desiderato.␍
+<br>␍
+Per il resto non ci sono molti cambiamenti; due proprietà sono state aggiunte alla classe per salvare␍
+il numero della colonna e la posizione quando inizia la colonna, e la chiamata a <a href='../doc/multicell.htm'>MultiCell()</a> specifica␍
+una larghezza di 6 centimetri.␍
