How to build a table with specific multicolumns?

Your question unfortunately not provide enough information about desired table, so the following suggestion is based on guessing:

documentclass{article}
usepackage{tabularx}
newcommandmccc[1]{multicolumn{3}{c|}{#1}}

begin{document}
    begin{table}
begin{tabularx}{linewidth}{|l|*{9}{>{centeringarraybackslash}X|}}
    hline
        &   mccc{Rouge 1}  &   mccc{Rouge 2}  &   mccc{Rouge 2}  
        cline{2-10}
        & F1 & P & R & F1 & P & R & F1 & P & R                      
    hline
text    &    &   &   &    &   &   &    &   &                        
    hline                          
        &    &   &   &    &   &   &    &   &                             
    hline
        &    &   &   &    &   &   &    &   &                                 
    hline
end{tabularx}
    end{table}
end{document}
