you can try adding scrolltop in highlight function keep highlighted item @ top of list long possible based on tableindex variable , height of row:

$('#areaitens').animate({     scrolltop: $('#data tbody tr:eq('+tableindex+')').height() * tableindex }, 0);  

this ensure container showing highlighted item. can play demo here.
