a parte WP che non c'entra una mazza (è un CMS per altri usi),
dovresti veramente considerare di creare un programmino dinamico

in ogni caso... una soluzione semplice è assegnare una classe alla cella di tuo interesse.
esempio:
codice:
CSS
.occupato{background:red;}
.libero{background:green;}


HTML
<tr>
<td class="occupato"></td>
<td class="libero"></td>
</tr>
E' quello che volevo evitare di fare, sarebbe una cosa infinita.

Per capirsi, è questo:
codice:
<table class="tabella">						<tr> 
						  <th id="vuoto"></th> 
						  <th colspan="5">Lun 14</th>
						  <th colspan="5">Mar 15</th>
						  <th colspan="5">Mer 16</th>
						  <th colspan="5">Gio 17</th>
						  <th colspan="5">Ven 18</th>
						  <th colspan="5">Dom 20</th>
						  </tr> 
						 <tr> 
						<tr> 
						  <th>Orario</th> 
						  <th>1</th> 
						  <th>2</th> 
						  <th>3</th>
