javascript - グループをソートせずにng-tableの行をソートする

Question

グループ モードでは、いくつかのフィールドでグリッドを並べ替えると、ngTable がグループを並べ替えます。したがって、グループは、フィールドでソートするたびに「ジャンプ」します。グループを「ジャンプ」せずにグループ内の行のみをソートするための解決策が見つかりません。

この質問は、ngTable の github の開発者向けの問題でまだ回答がありません。誰かがこの問題の解決策を知っているかもしれません

HTMLの私のテーブル:

  <table ng-show="!loading" ng-table="invoiceGrid" class="table invoices" if-empty="invoiceGrid">
    <thead>
        <tr>

                    'sort-asc': invoiceGrid.isSortBy(column.field, 'asc'),
                    'sort-desc': invoiceGrid.isSortBy(column.field, 'desc')
                    }"
