deferRender with vertical scroll fitting

Loren Maxwell

Just to confirm . . .

If I understood the explanation from this blog post correctly: https://datatables.net/blog/2017-12-31

then am I correct in believing that deferRender will work if set to true?

The deferRender docs state this:

if you load a data set with 10,000 rows, but a paging display length of only 10 records, rather than create all 10,000 rows, when deferred rendering is enabled, DataTables will create only 10

In general you will enable scrollY and disable paging. Without paging deferRender will be negated as all the rows are on the single page. I wasn't sure of this so I created this example:
http://live.datatables.net/jarelilo/1/edit

You can see with paging false all the rows are rendered. Removing paging: false will render 10 rows but scrolling will be limited to the current page.

Thanks, Kevin -- I was hoping this could be a nice lightweight replacement for Scroller, which it is, but being able to take advantage of deferRender would have completed it!
