  $("tr:odd td:nth-of-type(1)").prepend("Some prepended text. ");
  

  only gets the elements that are on the page at the time. Use the DataTables API to get all rows. For example table.rows().nodes() will get all nodes across all pages (note that if you are Ajax loading, which your example isn't, then deferRender would need to be disabled for that to work).

  Also I would very strongly discourage you from using jQuery or DOM methods to update the table's data. Use the DataTables API again, otherwise it won't know that you've changed the data.

  Now at https://live.datatables.net/jemogewe/1/edit

  works fine.

  script is

  var table = new DataTable('#example');

  table.on('draw', function () {

  var _clicked = false;

  if(!_clicked){
  _clicked = true;

  $("tr:odd td:nth-of-type(1)").prepend("Some prepended text. ");
  }

  });

  var _clicked = false;
  $('p').click(function(){

  if(!_clicked){
  _clicked = true;

  $("tr:odd td:nth-of-type(1)").prepend("Some prepended text. ");
  }
  })

  but if click the next button repeated then the prepend data again added.

  how to stop adding again to the exists ?

  You would need to check the row to see if you have already prepended the data or not. You could perhaps set a flag on the tr for the row and then check that flag.

  okay. i will try it.

  in the meantime

  can you show me how to program three html buttons

  1) first (if clicks move to the first page of the table)

  2) middle (move to the middles page of the total pages)

  3) last (move to last page)

  to do pagination.

  https://live.datatables.net/rolinojo/1/edit

  create the test case wiith buttons there.

  but don't know the parameters and sequences.

  welome all possible helps from all.

  First and last are trivial - use page() with first or last:

  table.page('first').draw(false);
  

  For the middle of the table, you need to workaround where the middle is, using page.info().

  Your example updated: https://live.datatables.net/hobuhipo/1/edit .

  I thought I had? My example shows the three things you asked for.
