PropertyValueFactory を使用するのではなく、必要な形式でアドレス情報を取得するには、カスタム セル値ファクトリを定義する必要があると思います。
次のサンプルは読み取り専用テーブル用です。テーブル内のメッセージ データを編集可能にする必要がある場合、ソリューションは非常に複雑になります。
fromColumn.setCellValueFactory(new Callback<CellDataFeatures<Message, String>, ObservableValue<String>>() {
@Override public ObservableValue<String> call(CellDataFeatures<Message, String> m) {
// m.getValue() returns the Message instance for a particular TableView row
return new ReadOnlyObjectWrapper<String>(Arrays.toString(m.getValue().getFrom()));
}
});
以下は、カスタム セル値ファクトリの使用方法を示す実行可能なサンプル (およびサンプル データ ファイル) です。サンプル データ ファイルをアプリケーション Java プログラムと同じディレクトリに配置し、ビルド システムがサンプル ファイルを、アプリケーション用にコンパイルされたクラス ファイルを含むビルド出力ディレクトリにコピーすることを確認します。アプリケーションをコンパイルして実行するには、パスにjavamail jar ファイルが必要です。

First alpha quality release, everything critical is now implemented. From
now on it's mostly stabilization and optimization. Features that can't break
existing code could still be added, especially SSL and authentication stuff.

v0.95 2002-07-31 Timo Sirainen <tss@iki.fi>
+ Initial SSL support using GNU TLS, tested with v0.5.1.
TLS support is still missing.
+ Digest-MD5 authentication method
+ passwd-file authentication backend
+ Code cleanups
- Found several bugs from mempool and ioloop code, now we should
be stable? :)
- A few corrections for long header field handling
