我已经按自己想要的方式对齐了表格中的值。但是，出于某种原因，这完全弄乱了我的第一行。我只想让标签位于值上方的中央。我该如何解决这个问题？
提前谢谢您！

答案1
首先，您需要将标题单词“cheese”、“butter”等括在花括号中，以告知包的机制siunitx它们是单词，而不是数字。（特别是字母“e”，容易混淆S列类型。）
其次，为了节省水平空间，您应该从朴素的S列类型（将整个列内容集中在小数点上）切换到诸如 之类的类型S[table-format=-1.6]。我还会发出指令\sisetup{table-align-text-post = false}，以避免数字和尾随星号之间出现任何间隙。
第三，我将\hline用 booktabs 包的线条绘制宏替换指令：、、、\toprule和。请参阅下面的代码以了解此想法的实现。我也不会\cmidrule执行。\midrule\bottomrule\addlinespace\renewcommand{\arraystretch}{1.7}

这是你想要的吗？我必须加载geometry以防止表格溢出到边距。
\documentclass{article}
\usepackage{geometry}
\usepackage{float}
\usepackage{siunitx}
\usepackage{tabularx}
\begin{document}
\begin{table}[H]

带tabularray包装，在标准article文档中：
\documentclass{article}
%---------------- Show page layout. Don't use in a real document!
\usepackage{showframe}
\renewcommand\ShowFrameLinethickness{0.15pt}
\renewcommand*\ShowFrameColor{\color{red}}
%---------------------------------------------------------------%
\usepackage{tabularray}
\UseTblrLibrary{booktabs, siunitx}
\begin{document}
\begin{table}[ht]
\begin{talltblr}[
caption = {Second stage estimation of own- and cross-price elasticities},
label = {cross_price_2d},
note{} = {*: $p<0.10$,\quad
**: $p<0.05$,\quad

]{colsep = 3pt,
colspec = {@{} l *{5}{X[c,si={table-format=-1.3{**}}]} @{}},

答案4
您想要指定table-format并使用tabular*，而不是tabularx。
我还建议使用booktabs功能，不要将设置\arraystretch为 1.7 这样的大值。另外，避免[H]让表格浮动，除非您想破坏文档的排版方面。
\documentclass{article}
\usepackage{siunitx,booktabs}
\begin{document}
\begin{table}[htp]
\centering
\setlength{\tabcolsep}{0pt}% leave the computations to TeX
\begin{tabular*}{\textwidth}{
@{\extracolsep{\fill}}
l
*{5}{S[table-format=-1.3***]}
@{}
}
\toprule
&\multicolumn{5}{c}{Price} \\
\cmidrule{2-6}
& {Cheese} & {Butter} & {Milk} & {Yoghurt} & {Cream} \\
\midrule
Cheese & -0.847*** & 0.002 & -0.068*** & -0.066*** & -0.031** \\
Butter & 0.017 & -0.996*** & 0.007 & 0.008 & -0.028\\
Milk & -0.224*** & 0.002 & -0.846*** & 0.029 & 0.016 \\
Yoghurt & -0.208*** & 0.018 & 0.052 & -0.748*** & -0.033 \\
Cream & -0.289*** & -0.072 & 0.039 & -0.091*** & -0.631*** \\
\midrule[\heavyrulewidth]
\multicolumn{6}{l}{\footnotesize * p$<$0.1, ** p$<$0.05, *** p$<$0.01}
\end{tabular*}
\caption{Second stage estimation of own- and cross-price elasticities}
\label{cross_price_2d}
\end{table}
\end{document}
