Answer 1

Edit: It seems that you expected that someone make this table from scratch for you ... I give below only a start point how to make table yourself. Therefore from your new image in question I consider only few table rows. The column heads are still based on guessing.

\documentclass{report}
    \usepackage{geometry}
    \usepackage{makecell,multirow,tabularx}
\renewcommand\theadfont{\bfseries}
        \usepackage[table]{xcolor}         
%\makeatletter %doesn't work
%\g@addto@macro{\table[ht]}{\fontsize{9pt}{10.8pt}\selectfont}
%\makeatother

\newcolumntype{L}{>{\raggedright\arraybackslash}X}% <-- new
\newcolumntype{C}[1]{>{\centering\arraybackslash}p{#1}}

\begin{document}
    \begin{table}[ht]
\footnotesize
\renewcommand*{\arraystretch}{1.2}
    \centering
\caption{Methodologies S}
  \begin{tabularx}{\textwidth}{|L|L|L|*{7}{C{0.6cm}|}}
    \hline
\multicolumn{10}{|l|}{Approach: Development Process}         \\
    \hline
\multicolumn{3}{|c|}{}
    &   \multicolumn{7}{c|}{\thead{Methodology}}            \\
      \cline{4-10}
\multicolumn{3}{|c|}{\thead{Feature}}
    & aaa & bbb & ccc & ddd & eee & f f f & ggg \\
      \hline
\multirowcell{3}{Project\\ management\\ processes}
    &  \multicolumn{2}{l|}{initiation}
        &   &   &   &   &   &   &                           \\ 
      \cline{2-10}
    &  \multicolumn{2}{l|}{monitoring and control}
        &   &   &   &   &   &   &                           \\
      \cline{2-10}
    &  \multicolumn{2}{l|}{Management}
        &   &   &   &   &   &   &                           \\
      \hline
\multirowcell{4}{Ontology\\ development-\\oriented\\ processes}
        &   \multirowcell{2}{Development\\ proces}
            &   requirements process   
        &   &   &   &   &   &   &                           \\
      \cline{3-10}
        &   &   design process
        &   &   &   &   &   &   &                           \\
      \cline{3-10}
        &   &   implementations process
        &   &   &   &   &   &   &                           \\

    \hline
    \end{tabularx}
\label{ch7:tab:experiencesinpracticalphysics}
    \end{table}
\end{document}

As you can see, I use some new packages: makecell for column headings (macro \thead) and multi row cells (macro multirowcell), multirow for support of makecell package for ˙multirowcellandtabularx, from which is used column typeXfor multi line cells with self-calculate width. Last seven columns are based onp{6mm}type column (redefined intoC` with centering cells content).

Since it seems that table is wide than text width, probably it be sensible to make it in landscape orientation (I haven't any idea about last seven columns with, selected 6mm is pure speculation).
