Question

my table is defined like:


\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                                                                   \

\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}

and as a result I get:

But I would like to create it like:

Could you please help?

My document is based on a specific, rather large class. But there is nothing there regarding tables. I thought this problem was something general. I generated the table on https://www.latex-tables.com/ and there was the information: "This table will import one package : vcell." so I added it at the beginning of my document: `usepackage{vcell}. — bLAZ, Apr 15 '21 at 19:42
@F.Pantigny I found what makes difference \usepackage[colorinlistoftodos,prependcaption,textsize=tiny,obeyFinal]{todonotes} It is used for TODO notes according to: https://tex.stackexchange.com/questions/9796/how-to-add-todo-notes — bLAZ, Apr 15 '21 at 20:29
In fact, the problem comes from an incompatibility between vcell and calc (which is loaded by todonotes). I have reported that incompatibility to the author of vcell and the problem will be solved in the next version of vcell released on CTAN. — F. Pantigny, Apr 16 '21 at 09:35

Here is a way to do that table with 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}

You need several compilations (because nicematrix uses PGF/tikz nodes under the hood).

Using recent MikTeX installation I cant reproduce your problem, however you may consider the following solution for your table:

\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
Parametersused for prediction of 
    & Parameter type 
        & Parameter
            & Value                                         \
    \midrule
High-Energy Proton SEU Rate 
    &  Weibull Fit 
        & Saturated upset cross-section [\si{\centi\metre^2\per bit}]\newline 
          Onset [\si{\mega\electronvolt}]\newline 
          Width [\si{\mega\electronvolt}]\newline 
          Exponent

            & 3.0e-15\newline 18\newline 12\newline 1.5     \
    \addlinespace
Heavy Ion\newline SEU Rate

    & Weibull Fit 
        & Saturated upset cross-section [\si{\centi\metre^2\per bit}]\newline 
          Onset [\si{\mega\electronvolt}-\si{\centi\metre^2\per\milli\gram}]\newline
          Width [\si{\mega\electronvolt}-\si{\centi\metre^2\per\milli\gram}]\newline
          Exponent 
            & 2.0e-09\newline 0.8\newline 27\newline 0.88   \
    \bottomrule
\end{tabularx}
    \end{table}
\end{document}
