Is it possible to do this paginated without a background image?

I am trying to implement pagination on the server side, for example datetable , and I found the backbone.paginator library , I do not know if there is anything else.

In their examples, they used another library to help accomplish this, backgrid.js and its paginator plugin

Is it possible to do this paginated without a Backgrid? Could you add any example?

:

  CREATE TABLE `pagination` (
 `id` INT( 16 ) NOT NULL AUTO_INCREMENT PRIMARY KEY ,
 `name` VARCHAR( 50 ) NOT NULL ,
 `age` INT( 3 ) NOT NULL ,
 `company` VARCHAR( 50 ) NOT NULL
  )

400 :

   $i=0;
   while ($i< 400){
   $pag="insert into pagination (id,name,age,company) VALUES 
  ('NULL','john','40','google')";
  $excu=$mysqli->query($pag);
