Longtable 比 textwidth 更宽

Question

假设我有一张跨多页的表格

\documentclass[DIV=8]{scrartcl}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{booktabs,array,ragged2e,longtable}
\newcolumntype{P}[1]{>{\RaggedRight\arraybackslash}p{#1\textwidth}}

\usepackage{enumitem}
%% Create a very compact itemized list environment
\newlist{mylist}{itemize}{1}
\setlist[mylist]{label=\textbullet, nosep, wide, 
                 leftmargin=*, % hanging indentation
                 before=\vspace{-0.50\baselineskip},
                 after =\vspace{-0.8\baselineskip}}
\begin{document}

\setlength\tabcolsep{0pt} % <--- important
\setlength\LTleft{0pt}

我需要表格比文本宽度更宽 - 在纵向模式下。使用geometry建议的包这里是不可行的，因为表格从新页面开始。但我想将它放在我的文本流中。有没有办法让长表比文本宽度更宽？

Answer 1

更改 \LTleft 和 \LTright 的值：例如，

\setlength\LTleft{-40pt}
\setlength\LTright{-40pt}

Answer 2

使用xltabular具有同名环境的包：

\documentclass[DIV=8,captions=tableabove]{scrartcl}
[...]
\usepackage{booktabs,array,ragged2e,xltabular}
\newcolumntype{P}[1]{>{\RaggedRight}p{#1\textwidth}}

\usepackage{enumitem}
\newlist{mylist}{itemize}{1}
\setlist[mylist]{label=\textbullet, nosep, wide, 
    leftmargin=*, % hanging indentation
    before=\vspace{-0.50\baselineskip},
    after =\vspace{-0.8\baselineskip}}
\begin{document}

\begingroup 
\setlength\tabcolsep{2pt}       
\begin{xltabular}{\linewidth}{@{} >{\RaggedRight}X >{\RaggedRight}X P{0.22} @{} }
        \caption{My caption} \label{my-label}\\ 
        \toprule
