使用工具将内容转换为无人能读懂的 LaTeX 代码非常方便。不，事实并非如此。像这样的简单表格应该有简单的代码。
我的建议：
\documentclass{article}
\usepackage{booktabs}
\begin{document}
\begin{table}
\centering
\caption{Dependency on the variable Y. No Wombats can be found in this table.}
\medbreak
\label{tab:addlabel}%
\begin{tabular}{crrr}

您发布的代码简直太糟糕了。究竟是谁教您这样编程的？！您是否在使用某种转换为 LaTeX 的工具？如果是，请立即停止使用它！它弊大于利。
正如@Johannes_B 在他的回答中所做的那样，我必须首先删除所有\multicolumn包装器。我还删除了所有\textbf突出显示 -根本就没有必要。（讽刺意味。）然后我删除了所有\hline指令（既然您似乎正在使用该booktabs包，那么它们为什么还在那里）并使用该siunitx包及其S列类型将数字数据与相应的小数标记对齐。
顺便问一下，为什么系数估计值的小数点后显示 4 位数字，而相关标准误差只显示 3 位数字？显示 4 位数字而不是 3 位数字可能传达什么含义？这是自学的习惯，还是有人教你这种相当可疑的做法？
