So I am trying to make a table in Latex for categorizing different types of something (in my example I have debt). But I want to have 4 "headlines" and I currently can only make 2. I will post a sample for clarity. Basically I want the line under the "private debts" to be equally long as for the above ones.
\begin{table}[h]
\begin{tabularx}{\linewidth}{>{\parskip1ex}X@{\kern4\tabcolsep}>{\parskip1ex}X}
\toprule
\hfil\bfseries Short-term public debt
&
\hfil\bfseries Long-term public debt
\\\cmidrule(r{3\tabcolsep}){1-1}\cmidrule(l{-\tabcolsep}){2-2}
%% PROS, seperated by empty line or \par
\begin{itemize}
\item Commercial paper
\end{itemize}
\begin{center}
\underline{\textbf{Short-term private debt}}
\begin{itemize}
\item Commercial bank loans
\item Trade credit
\item Nånting
\end{itemize}
\end{center}
&
%% CONS, seperated by empty line or \par
\begin{itemize}
\item Public bonds and notes
\end{itemize}
\begin{center}
\underline{\textbf{Long-term private debt}}
\begin{itemize}
\item Commercial bank loans
\item Private bonds and notes
\end{itemize}
\end{center}
\\\bottomrule
\end{tabularx}
\caption{Pros and cons of an IPO}
\end{table}
