wpf - 表の列幅と水平方向の配置

Question

インターネット全体を検索しましたが、テーブルの列をコンテンツの幅に合わせて拡大する簡単な解決策と、テーブルを画面の中央に集中させる方法が見つかりません。常に左揃えです。やってみ<TableColumn width="Auto">ました。それはトリックをしませんでした。唯一うまくいったのは<TableColumn width="200">. 列をコンテンツの幅に合わせて拡大するにはどうすればよいですか? また、テーブルを画面の中央に配置するにはどうすればよいですか? または、グリッドオプションに頼るべきですか?

ここに私のXAMLがあります:
