The HTML source is far from being valid : 
 - </> is not a valid HTML tag
 - 1px thin ffffff >> you forgot the # before 000000
 - the table's attributes dont need a unit, for example you should use width="300px" but width="300" (but the units are still required in the style attribute)
 - you shouldn't use <br> between LI tags

Be sure that accesses to $ArrayofDates don't throw errors and that it works 
with or without the <script type="text/php> element (note that you need to set 
the DOMPDF_ENABLE_PHP to true for this element to be taken into account).
