Set multiple columns in protected function getDefaultTableSortColumn()

Is it possible to order a table by multiple columns, just like:

 $query->orderBy('col1', 'asc')->orderBy->('col2', 'asc')

 $query->orderBy('col1', 'asc')->orderBy->('col2', 'asc')

 $query->orderBy('col1', 'asc')->orderBy->('col2', 'asc')

 $query->orderBy('col1', 'asc')->orderBy->('col2', 'asc')
