    All Gaul is divided into three parts, one of which the Belgae inhabit, the Aquitani another, those who in their own language are called Celts, in our Gauls, the third. All these differ from each other in language, customs and laws. The river Garonne separates the Gauls from the Aquitani; the Marne and the Seine separate them from the Belgae.

Esta solución funciona, pero quiero más flexibilidad. ¿Cómo, por ejemplo, voy a redefinir \leftpaddingpara centrar todas las tablas a la vez? Debería ser posible, al menos en dos pasadas. La opción de justificar correctamente tampoco vendría mal. También se aceptan soluciones completamente diferentes para el mismo objetivo.

Answer 1

Aunque no entiendo lo que quieres, aquí tienes una solución (que con suerte se adapta a tus necesidades) usando el pgfkeyspaquete -. Hice los subtítulos de manera que se puedan etiquetar (usando la label=clave) pero no usan el \captioncomando internamente. Además, no usa su comando \leftpaddingsino la paddingtecla -.

EDITAR: Tenga en cuenta que he modificado ligeramente el código anterior.

El uso del placedtabularentorno es normal tabular, excepto que en el argumento opcional puede usar una key=valuesintaxis separada por comas. Las siguientes claves están disponibles:

• stretch: el valor utilizado paraarraystretch
• place: la ubicación de la mesa. Disponibles son left, rightymiddle
• padding: el espacio al margen izquierdo o derecho con place=lefto place=right, respectivamente
• caption: el título utilizado para la tabla
• scaption: se utiliza el nombre de la tabla \listoftables, si no captionse utiliza. Si captionno se utiliza, esto no tiene ningún efecto.
• label: la etiqueta utilizada para hacer referencia a la tabla

Cuando utiliza una de estas claves en un placedtabularentorno, los efectos son solo locales y no afectan a ninguna otra tabla configurada con este entorno.

De las claves antes mencionadas place, stretchy paddingtienen un valor predeterminado, que se establece entre corchetes y default/.style={...}se usa dentro de la primera llamada de \pgfkeysen el MWE anterior. También está el comentario "cambie la configuración predeterminada aquí".

EDITAR2: El siguiente código es todo lo que está entre \makeatlettery \makeatothery no establece la 'tabla xy' delante del título. Debido a esto, también eliminé la labelclave ya que las referencias no funcionarán con esto.

EDIT3: Código completo (sin labely sin Table x.y:prefijo) que incluye dos opciones más:

• fontson interruptores de fuente aplicados a la tabla (cosas \bfseriescomo \footnotesizeo \small)
• captionfont¿Se aplican cambios de fuente al título?

Ambos tienen el valor predeterminado de no realizar cambios en los interruptores de fuente circundantes. Si se usa, restablezca el tamaño y la fuente y aplique el argumento proporcionado.
