有办法吗？我的所有东西都是左对齐的；但是我想让它们居中。怎么做？
另请相关：如何使所有标题加粗？

If I put this in at the moment it looks like my actual text and so there is lttle way to discern between the two.}

请原谅我写序言，因为我真的不知道什么与什么相关，我只知道这些都是随着时间的推移而收集起来的，以便能够编写我的整个文档，因此所有这些都会在某个时候使用。如果你想我可以将它们编辑掉...
因此，我想要一种方法来全局加粗、集中和更改所有标题的字体大小，集中的意思是居中对齐，这样它们就不会左对齐。
答案1
不需要额外的包；因为您正在加载caption，您可以使用其功能：
\documentclass[a4paper,12pt,fleqn,titlepage]{report}
\usepackage{caption}
\captionsetup{width=.75\textwidth,font={bf,scriptsize},skip=0.3cm,within=none}
\begin{document}
\chapter{Test}
\begin{table}
\centering
\caption{Load of stuff above the table which is wider than the table, can use width to limit that as above but want it centralised, also might be numbers in here which means when I want to embolden the entire caption from the preamle so that it does it for all figures in my document that the numbers like this $n=1,2,3,4,5,6$ and $7$ will embolden too. If I put this in at the moment it looks like my actual text and so there is lttle way to discern between the two.}
\begin{tabular}{| l | l | l |}
\hline
Thing1 & Thing2 & Thing3 \\ \hline
blah1 & blah2 & blah3 \\ \hline
\end{tabular}
\label{table:stuff}
\end{table}
\end{document}
答案2
这是否更接近您要查找的内容？第一个表就是您拥有的。第二个使用boxhandler。标题宽度、标题的字体大小和标题中普通文本的粗体都已在序言中更改，并将应用于所有表格和图形。标题中的粗体数学不能在表格标题中全局更改，除非在文档的其余部分也进行更改。因此，\mathbf是使用数学的每个图形标题的一部分。我使用的参数是 caption width=.5\textwidth并且标题为 scriptsize bold。
