I want to create the table as is shown in the following picture.
Could you please help me?

Actually, it's the other way round; initially you declare 5 columns and, in the first row, using \multicolumn you span some cells to occupy to of them.
In the following example, the packages siunitx and booktabs were used to improve the table formatting:
\documentclass{article}
\usepackage{siunitx}
\usepackage{booktabs}
\begin{document}
\noindent\begin{tabular}{lSSSS}
\toprule
& \multicolumn{2}{c}{A} & \multicolumn{2}{c}{Most Mon} \\
\cmidrule(r){2-3}\cmidrule(l){4-5}
Methods & {Time [\si{\second}]} & {RunCount} & {Time [\si{\second}]} & {RunCount} \\
\midrule
C & 12.3 & 5 & 34.6 & 7 \\
D & 1.35 & 5 & 4.93 & 7 \\
\bottomrule
\end{tabular}
\end{document}
Of course, instead of S you could use any other column type (and deal with possible alignments in other ways) such as c, l, r, or p{<length>}.
In a comment it has been requested to produce the table with the vertical rules; here it is:
\documentclass{article}
\usepackage{siunitx}
\begin{document}
\noindent\begin{tabular}{| l | S | S | S | S |}
\cline{2-5}
\multicolumn{1}{c|}{}& \multicolumn{2}{c|}{A} & \multicolumn{2}{c|}{Most Mon} \\
\hline
Methods & {Time [\si{\second}]} & {RunCount} & {Time [\si{\second}]} & {RunCount} \\
\hline
C & 12.3 & 5 & 34.6 & 7 \\
D & 1.35 & 5 & 4.93 & 7 \\
\hline
\end{tabular}
\end{document}
Here is a start for you.

This is one way to do it:
I suggest you to look up on the LaTeX Wikibook when you need some general information. For any particular package you use, always read its documentation on the CTAN. A very handy general reference is Stefan Kottwitz's LaTeX Cookbook. It's not gratis, however, Packt often make some deals, so keep an eye on their site if you wish.
