我的表定义如下：
\documentclass{article}
\usepackage{vcell,caption}
\begin{document}
\begin{table}[ht]
\centering
\captionsetup{justification=centering}
\caption{Parameters}
\label{tab:ParametersErrorRatePrediction}
\begin{tabular}{llll}
\hline
\begin{tabular}[c]{@{}l@{}}Parametersused \\for prediction of:\end{tabular} & \begin{tabular}[c]{@{}l@{}}Parameter\\type\end{tabular} & Parameter & Value \\
\hline
\vcell{\begin{tabular}[b]{@{}l@{}}High-EnergyProton\\SEU Rate\end{tabular}} & \vcell{Weibull
Fit} & \vcell{\begin{tabular}[b]{@{}l@{}}Saturated upset cross-section $[cm^2/bit]$\\Onset$[MeV]$\\Width $[MeV]$\\Exponent\end{tabular}} & \vcell{\begin{tabular}[b]{@{}l@{}}3.0e-15\\18\\12\\1.5\\\end{tabular}} \\[-\rowheight]
\printcellmiddle & \printcellmiddle & \printcelltop & \printcellmiddle \\
\begin{tabular}[c]{@{}l@{}}Heavy Ion\\SEU Rate\end{tabular} & Weibull
Fit & \begin{tabular}[c]{@{}l@{}}Saturated upset cross-section $[cm^2/bit]$\\Onset $[MeV-cm^2/mg]$\\Width $[MeV-cm^2/mg]$\\Exponent\end{tabular} & \begin{tabular}[c]{@{}l@{}}2.0e-09\\0.8\\27\\0.88\end{tabular} \\
\hline
\end{tabular}
\end{table}
\end{document}
结果我得到：
但我想像这样创建它：
能否请你帮忙？

这里有一种使用 来制作该表的方法nicematrix。
\documentclass{article}
\usepackage{nicematrix,booktabs}
\usepackage{caption}
\usepackage{siunitx}
\usepackage{lipsum}
\usepackage{geometry}
\begin{document}
\lipsum[1]
\begin{table}[ht]
\centering
\captionsetup{justification=centering}
\caption{Parameters}
\label{tab:ParametersErrorRatePrediction}
\begin{NiceTabular*}{\textwidth}{@{\extracolsep{\fill}}lclc@{}}
\toprule
\Block{}{Parameters used \\for prediction of}
& \Block{}{Parameter\\type}
& Parameter
& Value \\
\midrule
\Block{4-1}{High-EnergyProton\\SEU Rate} & \Block{4-1}{Weibull Fit}
& Saturated upset cross-section (\si{cm^2/bit}) & $3.0\cdot 10^{-15}$ \\
&& Onset (\si{MeV}) & 18 \\
&& Width (\si{MeV}) & 12 \\
&& Exponent & 1.5 \\[1ex]
\Block{4-1}{Heavy Ion\\SEU Rate} & \Block{4-1}{Weibull Fit}
& Saturated upset cross-section (\si{cm^2/bit}) & $2.0\cdot 10^{-9}$ \\
&& Onset (\si{MeV}, \si{cm^2/mg}) & 0.8 \\
&& Width (\si{MeV}, \si{cm^2/mg}) & 27 \\
&& Exponent & 0.88 \\
\bottomrule
\end{NiceTabular*}
\end{table}
\end{document}
您需要进行多次编译（因为nicematrix在后台使用了 PGF/tikz 节点）。

使用最近的 MikTeX 安装我无法重现您的问题，但是您可以考虑为您的表采用以下解决方案：
\documentclass{article}
\usepackage[skip=1ex]{caption}
\usepackage{booktabs, tabularx}
\newcolumntype{L}{>{\raggedright\arraybackslash}X}
\newcolumntype{M}[1]{>{\raggedright\arraybackslash}m{#1}}
\usepackage{siunitx}
\begin{document}
\begin{table}[ht]
\centering
\small
\caption{Parameters}
\label{tab:ParametersErrorRatePrediction}
\setlength\tabcolsep{4pt}
\renewcommand\tabularxcolumn[1]{m{#1}}
\begin{tabularx}{\linewidth}{@{} M{7em} M{5em} L M{3.3em} @{}}
\toprule
