调整 LaTeX 上的水平表宽度

Question

我正在尝试创建一个长表并将其水平放置。我想调整表格以使其适合页面（水平）。目前是这样的：

我想让它看起来像这样：

另外，有没有办法（如第二张图片所示）将页码放在该位置（居中）。请注意，此表占很多页，以下是代码：

\usepackage{rotating}
\usepackage{longtable} 
\usepackage{pdflscape} 

\begin{landscape}
\scriptsize
\begin{longtable}{*{8}{|c|} }
\hline
Item Number & Item Description & Quantity & Capacity & Operating             
Conditions & Design Conditions & Construction Materials & Special         
Requirements \\ 
\hline
TK-100 & Feed 1 Storage Tank & 1 & 8147.6 m\textsuperscript{3} & 25         
bar, 25°C & 31.25 bar, 31.25°C & Steel & Spherical \\ 
\hline
TK-101 & Feed 2 Storage Tank& 1 & 37728.7 m\textsuperscript{3} & 25 
bar, 25°C & 31.25 bar, 31.25°C & Steel & Spherical\\ 
\hline
...
\end{longtable}
\end{landscape}

任何帮助，将不胜感激！

尝试：

\documentclass{article}
\usepackage{ltablex, makecell}
\newcolumntype{C}{>{\centering\arraybackslash}X}
\renewcommand\theadfont{\footnotesize}
\renewcommand\theadgape{}
\setcellgapes{3pt}
\usepackage{siunitx}
\usepackage{pdflscape}

\begin{document}
    \begin{landscape}
\footnotesize
\makegapedcells
\begin{tabularx}{\linewidth}{|*{4}{c|} *{4}{X|} }% in case that you like to havew centered cells' content, use "C" instead of "X"
\hline
\thead{Item\\ Number}
    & \thead{Item\\ Description}
        & \thead{Quantity}
            & \thead{Capacity}
                & \thead{Operating\\ Conditions}
                    & \thead{Design\\ Conditions}

包ltablex结合longtable和tabularx。对于单位我建议使用siunitx。对于列标题使用\thead包中的宏makecell

我不会使用垂直线，并且将水平线的使用量减少到最低限度。相反，我\hline宁愿使用包中的规则booktabs（\toprule，，以及在每个适合行之后插入）：midrulebottomrule\addlinespace
