Can anybody help me? I know how to build the table but I don’t know how to add the “Users” and “Movies” labels.

This is what I've tried so far:

begin{table}[H]

centering

text{ textbf{Movies}}

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





multicolumn{1}{c}{} & multicolumn{1}{c}{1} & multicolumn{1}{c}{2} 

& multicolumn{1}{c}{3} & multicolumn{1}{c}{4} & multicolumn{1}{c}{5} 

& multicolumn{1}{c}{6} & multicolumn{1}{c}{7} & multicolumn{1}{c}{8} \ hhline{~*8{|-}|}

1 & & 5 &   & 2 & 4    &    &  &  \ hhline{~*8{|-}|} 

2 & 4 &  & 3 & 1 &  &   & 3  &   \ hhline{~*8{|-}|} 

3 & & 5 & 4 &  & 5 &   & 4  &\ hhline{~*8{|-}|}

4 & &   &   &  &   & 1 & 1 & 2   \ hhline{~*8{|-}|}

5 & 3 &  & color{blue}textbf{?} &  & color{blue}textbf{?} & 3 & &  0 \ hhline{~*8{|-}|}

6 & & color{blue}textbf{?} & 2 &  & 4 &  &color{blue}textbf{?} &  \ hhline{~*8{|-}|}

end{tabular}

Thanks!

This is my recommended version, which doesn't use any tables at all, but a powerful tool called TikZ:

documentclass[tikz]{standalone}

usetikzlibrary{matrix}

begin{document}

sffamily

begin{tikzpicture}

matrix (m) [matrix of nodes,nodes in empty cells,nodes={minimum size=.75cm,anchor=center}] {%

& 5 &   & 2 & 4    &    &  &  \

4 &  & 3 & 1 &  &   & 3  &   \

& 5 & 4 &  & 5 &   & 4  &\

&   &   &  &   & 1 & 1 & 2   \

3 &  & color{blue}textbf{?} &  & color{blue}textbf{?} & 3 & &  0 \

& color{blue}textbf{?} & 2 &  & 4 &  &color{blue}textbf{?} &  \

};

draw[step=0.75] (m-1-1.north west) grid (m-6-8.south east);

begin{scope}[font=scriptsize]

foreach i in {1,...,8} path (m-1-i.north) node[above] {i};

foreach i in {1,...,6} path (m-i-1.west)  node[left]  {i};

end{scope}

path (m-1-5.north west) node[above=1em] {Movies};

path (m-3-1.south west) node[left=1em] {Users};

end{tikzpicture}

end{document}

I don't nest tables, but use a multirow to center "Movies" and "Users":

documentclass{article}

usepackage{xcolor}

usepackage{array}

usepackage{multirow}

renewcommandarraystretch{1.5}

begin{document}

sffamily

begin{tabular}{cc|c|c|c|c|c|c|c|c|}

&multicolumn{1}{c}{} & multicolumn{8}{c}{Movies}\

&multicolumn{1}{c}{} & multicolumn{1}{c}{1} & multicolumn{1}{c}{2} 

& multicolumn{1}{c}{3} & multicolumn{1}{c}{4} & multicolumn{1}{c}{5} 

& multicolumn{1}{c}{6} & multicolumn{1}{c}{7} & multicolumn{1}{c}{8} \ cline{3-10}

multirow{6}{*}{Users}&1 & & 5 &   & 2 & 4    &    &  &  \ cline{3-10}

&2 & 4 &  & 3 & 1 &  &   & 3  &   \ cline{3-10}

&3 & & 5 & 4 &  & 5 &   & 4  &\ cline{3-10}

&4 & &   &   &  &   & 1 & 1 & 2   \ cline{3-10}

&5 & 3 &  & color{blue}textbf{?} &  & color{blue}textbf{?} & 3 & &  0 \ cline{3-10}

&6 & & color{blue}textbf{?} & 2 &  & 4 &  &color{blue}textbf{?} &  \ cline{3-10}

end{tabular}

end{document}

You can nest tables.

documentclass{beamer}

usepackage{xcolor}

usepackage{array}

usepackage{hhline}

begin{document}

begin{frame}[t]

frametitle{Tables can be nested}

begin{tabular}{cc}

 & Movies\

 Users&

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





multicolumn{1}{c}{} & multicolumn{1}{c}{1} & multicolumn{1}{c}{2} 

& multicolumn{1}{c}{3} & multicolumn{1}{c}{4} & multicolumn{1}{c}{5} 

& multicolumn{1}{c}{6} & multicolumn{1}{c}{7} & multicolumn{1}{c}{8} \ hhline{~*8{|-}|}

1 & & 5 &   & 2 & 4    &    &  &  \ hhline{~*8{|-}|} 

2 & 4 &  & 3 & 1 &  &   & 3  &   \ hhline{~*8{|-}|} 

3 & & 5 & 4 &  & 5 &   & 4  &\ hhline{~*8{|-}|}

4 & &   &   &  &   & 1 & 1 & 2   \ hhline{~*8{|-}|}

5 & 3 &  & color{blue}textbf{?} &  & color{blue}textbf{?} & 3 & &  0 \ hhline{~*8{|-}|}

6 & & color{blue}textbf{?} & 2 &  & 4 &  &color{blue}textbf{?} &  \ hhline{~*8{|-}|}

end{tabular}

end{tabular}

end{frame}
