my problem is about this code:

documentclass{article}

usepackage[utf8]{inputenc}

usepackage[spanish]{babel}

usepackage{array}

newcolumntype{L}{>{raggedrightarraybackslash}p{.4linewidth}}

renewcommand{arraystretch}{1.2}



begin{document}



    title{empty}

    author{empty}

    maketitle



    begin{table}[h!]

        begin{center}

            begin{tabular}{L|L}

                textbf{P4/1} newline              

                sudo ifconfig serviciosB downnewline 

                sudo ifconfig serviciosA newline 172.24.1.1/24 newline

                sudo route add -net 172.24.2.0/24 gw 172.24.1.222

                & textbf{P4/3} newline 

                sudo ifconfig serviciosA down 

                newline

                sudo ifconfig serviciosB newline 172.24.2.1/24 newline

                sudo route add -net 172.24.1.0/24 gw 172.24.2.222 \  

                hline

                textbf{P4/2} newline 

                sudo ifconfig serviciosB down newline

                sudo ifconfig serviciosA newline 172.24.1.2/24 newline

                sudo route add -net 172.24.2.0/24 gw 172.24.1.222 & textbf{P4/4} newline 

                sudo ifconfig serviciosA down newline

                sudo ifconfig serviciosB newline 172.24.2.2/24 newline

                sudo route add -net 172.24.1.0/24 gw 172.24.2.222 \

            end{tabular}

        end{center}

    end{table}



end{document}

The issue is that I'd like to center the title in bold (P4/1,P4/2...), but if I include for example begin{center} textbf{P4/1} end{center} inside the table, there's a lot of space between the beginning of the table and the title.

I hope someone can help me. Thanks for your responses.

You can put the titles in their own row and use multicolumn{1}{c}{bold title}. Other than that, I defined a titlehead command which does the job:

documentclass{article}

usepackage[utf8]{inputenc}

usepackage[spanish]{babel}

usepackage{array}

newcolumntype{L}{>{raggedrightarraybackslash}p{.4linewidth}}

renewcommand{arraystretch}{1.2}%

newcommand{titlehead}[1]{hfilltextbf{#1}hfillnull}%



begin{document}



title{empty}

author{empty}

maketitle



begin{table}[h!]

    centering

    setlength{extrarowheight}{2pt}

        begin{tabular}{L|L}

            titlehead{P4/1} newline

            sudo ifconfig serviciosB downnewline

            sudo ifconfig serviciosA newline 172.24.1.1/24 newline

            sudo route add -net 172.24.2.0/24 gw 172.24.1.222

            & titlehead{textbf{P4/3}} newline

            sudo ifconfig serviciosA down

            newline

            sudo ifconfig serviciosB newline 172.24.2.1/24 newline

            sudo route add -net 172.24.1.0/24 gw 172.24.2.222 \

            hline

            titlehead{textbf{P4/2}} newline

            sudo ifconfig serviciosB down newline

            sudo ifconfig serviciosA newline 172.24.1.2/24 newline

            sudo route add -net 172.24.2.0/24 gw 172.24.1.222 

            & titlehead{textbf{P4/4}} newline

            sudo ifconfig serviciosA down newline

            sudo ifconfig serviciosB newline 172.24.2.2/24 newline

            sudo route add -net 172.24.1.0/24 gw 172.24.2.222 \

        end{tabular}

end{table}



end{document}

Like this?

Note that I've modified the L column type for automatic hanging indentation.

documentclass{article}

usepackage[utf8]{inputenc}

usepackage[spanish]{babel}

usepackage{array}    % for 'newcolumntype' macro

usepackage{ragged2e} % for 'RaggedRight' macro

newcolumntype{L}{>{RaggedRightarraybackslash%

   hangafter=1hangindent=1.5em}p{0.45linewidth}}

newcolumntype{C}{>{centeringarraybackslash}p{0.45linewidth}}

%% two handy shortcut macros:

newcommandmC[1]{multicolumn{1}{C|}{#1}}

newcommandmD[1]{multicolumn{1}{C}{#1}}



begin{document}

begin{table}[h!]

setlengthextrarowheight{2pt}

begin{tabular}{L|L}
