datatables remove rowgrouping

Answer 1

I found the solution - remove the draw callback that the grouping plugin creates and reset the group sorting:

var oSettings = jQuery('#table').dataTable().fnSettings();

for (f = 0; f < oSettings.aoDrawCallback.length; f++) {
    if (oSettings.aoDrawCallback[f].sName == 'fnRowGrouping') {
        oSettings.aoDrawCallback.splice(f, 1);
        break;
    }
}

oSettings.aaSortingFixed = null;

Hope this helps.
