Answer 1

With ajax, you can get the number of rows and calculete a number to sum to the progressbar, after that you shoud call with other ajax method to a php function which has a query with limit x (this number x shoud be pass by ajax param). After that, in the response of ajax, you can sum the % of the progressbar.
