Dato che una tabella  solo un'insieme di celle,  naturale costruirne una da esse. Il primo
esempio  praticato con l'approccio pi basilare possibile: semplici celle con bordi, tutte alla stessa dimensione
e allineate a sinistra. Il risultato  rudimentale ma veloce da ottenere.
<br>
<br>
La seconda tabella porta alcune migliorie: ogni colonna ha una sua larghezza, intestazione e sono centrate,
numerate e allineate a destra. In pi, sono state rimosse le righe orizzontali. Questo si fa attraverso
il parametro <code>border</code> del metodo <a href='../doc/cell.htm'>Cell()</a> che specifica quali lati della cella debbano essere
disegnati. Qui vogliamo il lato sinistro (<code>L</code>) e destro (<code>R</code>). Rimane il
problema della linea orizzontale per finire la tabella. Ci sono due possibilit: sia
controllare quando si arriva all'ultima riga del ciclo, in questo caso utilizzare <code>LRB</code> per il parametro <code>border</code>
 or, come  stato fatto qui, aggiungere la riga quando finisce il ciclo.
<br>
<br>
La terza tabella  simile alla seconda ma usa i colori. I colori di riempimento, del testo, e della linea
sono semplicemente specificati. L'alternaggio della colorazione delle righe  ottenuto alternando trasparenza
e colorazione delle celle.
