I want to make a table like this:

So I tried with this Latex code:

begin{table}[h!]

begin{center}

    begin{tabular}{|l|c|c|}

        hline multirow{2}{3cm}{Filter Type} & 

         multicolumn{2}{|c|}{Ideal impulse response $h_D(n)$} \

         cline{2-2} & $h_D(n), ; nneq 0$ & $h_D(0)$ \ hline

    end{tabular}

end{center}

end{table}

But I get this table instead:

I don't know how to fix my problem, so I appreciate if someone could help me.

A minimal modification to your code to get the vertical placing of "Filter Type" and the requested rule is:

documentclass{article}



begin{document}

begin{table}[h!]

begin{center}

  begin{tabular}{|l|c|c|}

    hline Filter Type

    & multicolumn{2}{|c|}{Ideal impulse response $h_D(n)$} \

    cline{2-3} & $h_D(n), ; nneq 0$ & $h_D(0)$ \ hline

  end{tabular}

end{center}

end{table}

end{document}

However, you should consider whether you need all these vertical rules. I guess this is just heading material for a table, in which case I would suggest:

documentclass{article}



usepackage{booktabs}



begin{document}



begin{center}

  begin{tabular}{l*{2}{c}}

    toprule

    Filter Type

    & multicolumn{2}{c}{Ideal impulse response $h_D(n)$} \

    & $nneq 0$ & $n=0$ \

    midrule

    X&$2$&$-1$\

    Y&$3$&$2$ \

    bottomrule

  end{tabular}

end{center}



end{document}

Note that a table environment is not necessary, particularly if you want placement at a particular point on the page. If you need a caption, then the captionof command from the caption package can be used.

See the documentation of the booktabs package for more advice on good style for tables.
