longtable 和 adjustbox/textwidth

Question

这个表格可以放在文本的宽度上吗？我尝试了很多方法，但都没有用。

\setlength\LTleft{0pt}
\setlength\LTright{0pt}
\begin{longtable}[c]{@{\extracolsep{\fill}}cccccccccc@{}}

\caption{Zoznam, zapojenie a parametre vedení 110 kV} \label{tab:long1} \\

Answer 1

假设您使用的是标准文档类（文章、报告或书籍）之一或基于标准文档类构建的文档类，则以下代码应该可以正常工作。相对于您发布的代码片段，主要变化是将单元移动到单独的标题行；这使得每列的宽度大大减小。

以下代码还包含对 slovak/babel 与该包的一些宏之间不兼容的修复booktabs。

\documentclass{article}
\usepackage{siunitx}
\usepackage[slovak]{babel}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage{longtable}
\usepackage{booktabs}

% fix incompatibility between babel/slovak and booktabs macros:

使用该tabularray包后，表格代码简单而简短：

\usepackage{lmodern}
\usepackage{tabularray}
\UseTblrLibrary{booktabs, siunitx}
    \DefTblrTemplate{conthead-text}{normal}{(Pokračovanie)}
    \SetTblrTemplate{conthead-text}{normal}
    \DefTblrTemplate{contfoot-text}{normal}{Pokračovanie na ďalšej strane \dots}
    \SetTblrStyle{contfoot-text}{font=\small\sffamily\itshape, gray5}
    \SetTblrTemplate{contfoot-text}{normal}
