I would like to create a table like the one I show in the image but I'm a bit lost.

Let's see if someone can help me.

Thank you.

Here's a solution which uses the l column type for the first column and the r column type for the six data columns. To give the table material a more open "look", no vertical lines are drawn, and the line-drawing macros of the booktabs package are used in place of hline and cline.

documentclass{article}

usepackage{booktabs} % for well-spaced horizontal rules

begin{document}



begin{center}

begin{tabular}{@{} l *{6}{r} @{}} % "@{}" eliminates horizontal whitespace padding.

toprule

Database & multicolumn{6}{c@{}}{Number of operations} \

cmidrule(l){2-7}

        &  10 &  50 &  100 & 1000 & 10000 & 100000 \

midrule

MongoDB &  61 &  75 &   84 &  387 &  2693 &  23354 \ 

RavenDB & 570 & 898 & 1213 & 6939 & 71343 & 740450 \ 

ldots\

MS Sql Express & 30 & 94 & 129 & 1790 & 15588 & 216479 \

bottomrule

end{tabular}

end{center}

end{document}

In addition to novski's answer, here is a variant using rules from booktabs for a more open appearance and siunitx for better alignment of number.

documentclass{article}

usepackage{multirow}

usepackage[group-minimum-digits=4]{siunitx}

usepackage{booktabs}



begin{document}



begin{tabular}{l

                 S[table-format=3]

                 S[table-format=3]

                 S[table-format=4]

                 S[table-format=4]

                 S[table-format=5]

                 S[table-format=6]}

  toprule

  multirow{2.5}{*}{Database} & multicolumn{6}{c}{Number of operations} \

  cmidrule{2-7}

                    & 10 & 50 & 100 & 1000 & 10000 & 100000\

  midrule

  MongoDB           & 61 & 75 & 84 & 387 & 2693 & 23354 \ 

  RavenDB           & 570 & 898 & 1213 & 6939 & 71343 & 740450 \ 

  bottomrule

end{tabular}



end{document}

Here is the variant without the multirow:

 toprule

 Database & multicolumn{6}{c}{Number of operations} \

 cmidrule{2-7}

i use this dependencies:

usepackage{longtable}

usepackage{multirow}

~

begin{longtable}{|l|c|c|c|c|c|c|}hline

  multirow{2}{*}{Database} & multicolumn{6}{c|}{Number of operations} \cline{2-7}

                    & 10 & 50 & 100 & 1000 & 10000 & 1000000\hlineendhead

  MongoDB           & 61 & 75 & 84 & 387 & 2693 & 23354 \ 

  RavenDB           & 570 & 898 & 1213 & 6939 & 71343 & 740450 \ hline

caption{Database evaluation}

label{tab:databaseeval}

end{longtable}
