What steps will reproduce the problem? 1. Init with: oTable.rowGrouping({iGroupingColumnIndex: 1}); 2. Create onClick event i.e. this: $('#example thead th').click(function() { oTable.rowGrouping({iGroupingColumnIndex: 2});}); 3. Click on table head

What is the expected output? What do you see instead? Expected new grouping on columnIndex 2, but nothing like that happen.

What version of the product are you using? On what operating system? I'm using dataTables 1.9.3 and Row grouping ver. 1.2.7

Please provide any additional information below.

oTable.rowGrouping({iGroupingColumnIndex: 1}); oTable.draw();

//call draw function, to redraw this, you should be fine.
