フリーヘッダ領域の適用
テーブルシートは、列ヘッダのフリーヘッダ領域を構成するために、applyFreeHeaderAreaメソッドを提供します。
フリーヘッダ領域のJSON作成
フリーヘッダ領域のJSON作成の際に、シートの名で数式を参照したい場合は（たとえば、"TableSheet1![ColumnName]"、"OtherSheet!A1"、"AVERAGE(TableSheet1[ColumnName])"）、keepUnknownFormulasシートオプションを有効にする必要があります：
以下はサンプルコードです：
ヘッダ領域の数式テキストボックスのサポート
ヘッダ領域では数式テキストボックスがサポートされており、ヘッダ領域のセルをダブルクリックして編集を開始するか、"=" キーを押すと数式を編集できます。
その後、テーブルシートの列や、フリーヘッダ領域の範囲を選択できます。
