I am trying to make a LaTeX table.
I have prepared the following code.
\begin{table}[htbp]
\caption{Combination Nomenclature, (Average Fill Factor)}
\resizebox{1.0\textwidth}{!}{
\begin{tabular}{|c||c|c|c|c|}
\hline
\textbf{Combination} &\multicolumn{4}{l|}{\textbf{Included Optional Steps}}\\
\cline{2-5}
&\textbf{1}&\textbf{2}&\textbf{3}&\textbf{4}\\
\hline\hline
\textbf{1}& X & & & \\
\hline
\textbf{2}& X & X & & \\
\hline
\textbf{3}& X & X & X & \\
\hline
\textbf{4}& X & X & &X \\
\hline
\textbf{5}& X & & X & \\
\hline
\textbf{6}& X & & X & X\\
\hline
\textbf{7}& X & & & X\\
\hline
\textbf{8}& & X & &\\
\hline
\textbf{9}& & X & X &\\
\hline
\textbf{10}& & X & X & X\\
\hline
\textbf{11}& & X & & X\\
\hline
\textbf{12}& & & X & \\
\hline
\textbf{13}& & & X & X \\
\hline
\textbf{14}& & & & X \\
\hline
\hline
\textbf{15}& \multicolumn{1}{l}{Nano Particles Deposited, Not Sintered} & & & \\
\hline
\textbf{16}& \multicolumn{1}{l}{Only Grinded Wafer 1, No Particles Deposited, Not Sintered} & & & \\
\hline
\textbf{17}& \multicolumn{1}{l}{Only Grinded Wafer 2, No Particles Deposited, Not Sintered} & & &\\
\hline
\end{tabular}}
\label{table:AverageFillFactor}
\end{table}
As you can see, the combinations 15-17 should be indipendent of the rows above and optional steps 1-4 should have equal width. The problem is that I am not sure, how to separate them.

One way would be to fix the width of the columns as in the first example:
It would be even better to eliminate the vertical lines as in the second example:
