links work in the same way as usual - the data generated via php is the same, the javascript used in datatables only changes how it appears
for example, if you were to look at a results page generated by dataassist, the edit button would look something like this...
<input type="button" class="formButton ResultsPageButton unstyled UpdateButton" value="" onclick="document.location.href='/admin/documents_update.php?DocumentID=<?php echo($row_WADAtbldocuments['DocumentID']); ?>
this still works within a datatable.
the pagination line you highlighted allows you to set the (maximum) number of pages displayed between the 'previous' and 'next' buttons - when you elect to use the fullnumbers paginaton option.
try changing the integer to see what i mean
