I am trying to have the inner text of each square of my \tabular
fill the whole space available. For example, in the tabular below, I would like my a2 and b2 occupy the entire column
under s2 in a way to not reveal clear empty spaces where would be c2 and d2.
\usepackage{amssymb}
\usepackage{multirow}
...
\begin{center}\begin{tabular}{|c|c|c|c|}
\hline
\multicolumn{4}{|c|}{\bf title}\\
\hline \hline
\bf s1 & \bf s2 & \bf s3 & \bf s4\\
\hline \hline
\multirow{4}{*}{$\varnothing$} & a2 & a3 & a4\\
& b2 & b3 & b4\\
& & c3 & c4\\
& & d3 &\\
\hline
\end{tabular}\label{table}\end{center}
Would anyone have a clue, please?
Edit:
\usepackage{amssymb}
\usepackage{multirow}
...
\begin{center}\begin{tabular}{|c|c|c|c|}
\hline
\multicolumn{4}{|c|}{\bf Requête}\\
\hline \hline
\bf s1 & \bf s2 & \bf s3 & \bf s4\\
\hline \hline
\multirow{5}{*}{$\varnothing$} & \multirow{2}{*}{a2} & a3 & \multirow{3}{*}{a4}\\
& \multirow{2}{*}{b2} & b3 & \multirow{3}{*}{b4}\\
& & c3 & \multirow{3}{*}{c4}\\
& & d3 &\\
& & e3 &\\
\hline
\end{tabular}\end{center}
After Ignasi post, I popularized to the entire table. But a malfunction appears under 's2':
