我有一个问题，我想提交一篇文章，但是我需要使用期刊提供的模板，但模板有多个限制，例如左侧有巨大的偏移量。现在我想要一个跨多页的表格（所以我不能使用表格环境），但我无法以正确的方式调整它。标题和表格注释应该从左侧开始，没有偏移量。表格本身应该居中。目前表格注释也不在表格的公共环境中。我希望有人有解决方案！
表 1 显示了它应该是什么样子。表 2 显示了它目前的样子。
这是我的示例代码：

先感谢您！
答案1
您可以使用负数 来移动边距中的长表\LTleft。标题caption也可以使用包和负边距来移动：
\usepackage{ltablex}
\usepackage{caption}
\captionsetup[longtable]{margin=-2.25in}
\setlength{\LTleft}{-2.25in}
答案2
编辑：
在澄清了您下面评论中的问题后，现在很清楚了，您还希望有宽度longtable，但不会突出到右边距。为此，提供了一种解决方案乌尔里克回答如下，所以我在这里添加了一些可能需要的更改（长表与环境中的表具有相同的宽度adjustwidth）：
看看您的 mwe 中的以下更改是否可以接受：
\documentclass{article}

\usepackage{changepage}
% Text layout

%\textwidth 5.25in
%\textheight 8.75in
% Captions will be left justified
\usepackage[aboveskip=1pt,labelfont=bf,labelsep=period,
justification=raggedright,singlelinecheck=off]{caption}
% Header and Footer
\usepackage{fancyhdr}
\pagestyle{myheadings}
\pagestyle{fancy}
\fancyhf{}
\setlength{\headheight}{27.023pt}
\rfoot{\thepage/\pageref{LastPage}}
\renewcommand{\footrule}{\hrule height 2pt \vspace{2mm}}
\fancyheadoffset[L]{2.25in}
\fancyfootoffset[L]{2.25in}
% ltablex package

- 关于表格注释，看看是否
threparttable（或threparttablex）可以改进写表格注释的技巧。 booktabs通过使用包中的规则并省略垂直规则，您将获得更专业的表格外观：
