Posición del título de la tabla

Question

Quiero que el título llegue hasta el lado izquierdo de la tabla, pero mantener toda la tabla centrada, pero no tengo idea de cómo hacerlo. ¿Puede algún experto ayudarme con esto? ¡Muchas gracias!

Answer 3

No estoy seguro de haber entendido su objetivo de formato.verbigracia.

Quiero colocar el título completamente en el lado izquierdo de la tabla pero mantener toda la tabla centrada.

He interpretado que este objetivo requiere una combinación de (a) un threeparttableentorno que incluya tanto la \captiondirectiva como el tabularentorno y (b) una \captionsetupdirectiva con las opciones justification=raggedrighty singlelinecheck=false.

No puedo evitar observar que los \multicolumn{1}{l}{...}envoltorios de los tres subtítulos son redundantes. Omita estos envoltorios por completo o reemplácelos con \multicolumn{6}{l}{...}envoltorios, como lo hice en el código siguiente.

Las líneas de marco en los bordes de la siguiente captura de pantalla están dibujadas porque el showframepaquete está cargado para este documento de prueba. No es necesario cargar este paquete en su documento real.

Answer 4

• Con tabularraypaquete, donde el formato de los títulos se deja al captionpaquete.
• Se utiliza talltblrla tabla, un tabularrayequivalente de threeparttable.

Editar:

• Para los títulos de los paneles se define un nuevo comando (por \NewTableComman), que recopila la configuración para esta fila: \setCell[c=6]{...}, forma de fuente y cara.
• Dado que \SetCell no permite (hasta donde yo sé) cambiar la separación de las columnas de las celdas con el uso de @{}sangría (colgar) de los textos de los títulos del panel, \panelse introduce el comando `\SetRow{...} para agregar espacio encima del título ( donde sea necesario) y desplazar el contenido de la fila hacia la izquierda:
