  The example has this error:

  Uncaught Error: RowGroup requires DataTables 2 or newer

  Here is the updated example using the Download Builder to get the latest Datatables code:

  As noted in the thread you linked to this example doesn't freeze the current group below the header.

  Note that I added scrollY to the example to replicate the jQuery iOSList plugin example linked to in the other thread.

  RowGroup doesn't support this feature. Based on my limited understanding of how RowGroup works it doesn't pay attention to scrolling events. The RowGroup display is updated only when the Datatable is redrawn which doesn't happen because of scrolling.

  I think to implement this one would need to create a scroll event that determines what is displayed in the scrolling window and insert, if needed, the grouped row. Instead of using the RowGroup maybe take a look at this Row Grouping example as a place to start. If using scrollY then all the rows in the table will be selected with the selector-modifier of { page: 'current' }instead of just the rows shown in the scroller window.

  Doesn't sound like an easy thing to develop, maybe @allan has some ideas.

  This sounded like a good Sunday morning challenge I created this example:

  Feel free to make any desired changes.

  I tested my example with the RowGroup extension and it works too.

  There are two changes:

  1. The current RowGroup extension uses the class dtrg-group instead of group used in the Row grouping example.
  2. Changed from using td to th to match what the extension uses for the inserted grouping rows. This is to match the styling used.
