Once my grid is complete and all data is loaded I'd like to rename all my column keys to be 0-column length. Since my data comes form a webApi its based on my variable names. And variables can not start with a number. Alternatively I'd like to be able to get my column index in the columnSorting event but the API does not expose this? So I have to do this to get it.

 for ( var c = 1; c < gridId.igGrid( "option", "columns" ).length; c++ )
                    {
                        if ( gridId.igGrid( "option", "columns" )[c].key == ui.columnKey ) colIndex = c;
                    }

That will not work since I really need my column to be the same name in some cases. So the best option I have then is to reorder my column keys at dataRendered.  Can this be done?

FYI: this is breaking the grid

                for ( var c = 1; c < gridId.igGrid( "option", "columns" ).length; c++ )
                {
                    gridId.igGrid( "option", "columns" )[c].key = c;
                }
