私が抱えている問題は、テーブル間の関係 (線) がテーブルを迂回するのではなく、テーブルをまたいでいることです。
MWE はかなり長いですが、ここにあります:

問題の画像はこちらです(もっとわかりやすいかもしれません) -
現在のようにボックスの上に線が引かれるのを止める方法がわかりません。この動作を防ぐために変更できる値が見つかりません。
ちなみに、これを行うのはかなり手間がかかるようです。他の方から代替方法の提案があれば、ぜひお聞かせください。
ありがとう
答え1
これは1つの解決策です。zig zag to
スタイルはデフォルト値0.5に設定されています。
zig zag to/.default=0.5
さらに、one to many
次の2つのスタイルもそのデフォルト値を使用しており、エラーの原因となっています。この提案では、スタイル定義zig zag to
から を削除しているone to many
ため、
\draw (<start>) to (<end>)
コマンドの構文ではdraw
なく、よく見られる相対座標と直交座標の描画スキルを使用します。
\draw (<start>) --++(x,0) |- (<end>);
内部ラベル(<start>)
とは(<end>)
まだ有効であり、ローカル座標が含まれているためです。

答え2
zig zag to
異なる座標を持つポイント間でのみ正常に動作しますx
。
たとえば、zig zig to
同じポイントに適した別のスタイルを定義しx
、それを使用して新しい を定義することができますone to many bis
。
one to many
のパラメータへのアクセスを追加して変更しましたzig zag to
。この方法ではエッジが重なり合いません。
