Cómo excluir la punta de flecha de tikzpicture

Question

Estoy intentando cortar la punta de flecha de esta imagen pero sin éxito. En segundo lugar, ¿hay alguna forma de dejar el texto justificado?

Answer 1

• Para empezar, comente/elimine los tres bloques del código que los comentarios identifican como parte de la flecha.
• En \matrix, elimine la última celda de cada fila. Eso es eliminar el último &y todo lo que esté entre él y \\.
• En el bloque de código que dibuja reglas horizontales, reemplace el número de columna 6con 5.
• Para los nodos, agréguelos righta las opciones y colóquelos at (mat-rowno-1.west)en lugar de (mat-rowno-3).
