グリッド:複数列のソート

デフォルトでは、FlexGridでは一度に1列のみをソートできます(列ヘッダーをクリックする)。

ユーザーが一度に複数の列をソートできるように、allowSortingプロパティを使用してこの動作を変更します。

列ヘッダーをクリックすると、その列のソートが追加または反転されます。 Controlキーを押しながらクリックすると、クリックした列のソートが削除されます。 ShiftキーとControlキーを押しながらクリックすると、すべてのソートが削除されます。

複数の列でソートする場合、グリッドのソート方向のグリフの横にある列ヘッダーにソートインデックスが表示されます。'wj-sort-index'クラスのスタイルを設定することにより、ソートインデックスの外観をカスタマイズできます。
