title: How to make a loop appending 20 -20 rows in a tableview when scrolling?
body: <p>I have a tableview, where I get sometimes 1000 or 40 or sometime even 4 values, but I want that when I got more than 100 values I want to display my array in a 10 - 10 scrolling.</p>
  
  <p>Scrolling the tableview up, I need a scrolling pause after 10 rows are scrolled up, with this code it is giving errors, My array is in [Any] and want to scrolling like Facebook and instagram</p>
  
  <p>I want to get my array into 10 rows first and then I can append the next 10.</p>
