デフォルトでは、テーブルシートはオブジェクトによってリモート要求を構成します。要求を手動で処理したい場合は、関数のオブジェクトを置き換えるだけで、データの変更が関数に渡されます。
データ変更の詳細は、概要と基本的な使い方の要求と応答セクションにあります。
AutoSyncモード
AutoSyncモードで要求を処理します：
Batchモード
Batchモードで要求を処理します：
データソースオプションの変更
テーブルがCRUDオプションの代わりにCRUD関数を使用している場合、セキュリティ上の問題から、JSONのシリアル化／逆シリアル化の後にこれらの関数を保存および復元することができません。
fromJSONメソッドを呼び出した後に、テーブルのデータソースオプションを設定すると、テーブルを再び動作させることができます。
データの再読み込み
テーブルのfetchメソッドを呼び出した際に、引数reloadがtrueの場合、テーブルのデータを再度読み込みます。
また、ビューのfetchメソッドは、テーブルのfetchメソッドと同じreload引数を持っています。
