I know using turn command and a sample code like this:

usepackage{rotating}



begin{turn}{90} Supervised Learning end{turn}}

we can rotate a text inside a cell, however, I couldn't find a way to vertically center this rotated text. Any suggestions is appreciated.

Here is the sample MWE:

begin{table}

    centering

    begin{tabular}{|>{centeringarraybackslash}m{0.5cm}|c|>{centeringarraybackslash}m{8cm}|}

        hline

        multicolumn{2}{|c|}{Classification} & References \ hline

        %multirow{2}{*}{{begin{turn}{90}Supervised Learningend{turn}}}   

        multirow{2}{*}{rotatebox[origin=c]{90}{Supervised Learning}} 

end{tabular}

    caption{A Classification}

    label{tab:Machine_Learning_models}

end{table}

since your question seems to be unstable system ... i'm afraid that my answer will miss your point as it was Mico answer (which finish with deletion) :-( )

anyway, for exercise:

• your rotated text is taller than rest of table, so it can not bo properly centered


• easier way to rotate cell content is use rothead macro from makecell package (for which you need to define cell height)


• vertically centering in multirow cell needs some manual tweaking

with this (and expand the table) I obtain the following result:

MWE:

documentclass{article}

usepackage{rotating}

usepackage{array,makecell,multirow}



begin{document}

begin{table}[htb]

    centering

    settowidthrotheadsize{Supervised Learning}

    begin{tabular}{| l | c |

                     >{centeringarraybackslash}p{8cm}|}

    hline

multicolumn{2}{|c|}{Classification}    &   References  \ hline

multirow{8}{*}[1.5ex]{rothead{Supervised Learning}}  

        &                               &  1            \ cline{2-3}

        &                               &  2            \ cline{2-3}

        &                               &  3            \ cline{2-3}

        &                               &  4            \ cline{2-3}

        &                               &  5            \ cline{2-3}

        &                               &  6            \ cline{2-3}

        &                               &  7            \ cline{2-3}

        &                               &  8            \ hline                end{tabular}

caption{A Classification}

    label{tab:Machine_Learning_models}

end{table}

end{document}

Addendum:
Font size of text in rothead is determined by headfont macro. Default value is footnotesize. It can be changed by

renewcommandtheadfont{normalsize}

(or whatever size, font family and shape you like). Considering above change of font size, the relvant part of MWE become:

documentclass{article}

usepackage{rotating}

usepackage{array,makecell,multirow}

renewcommandtheadfont{normalsize}% <-- added



begin{document}

begin{table}[htb]

    centering

    settowidthrotheadsize{theadfont Supervised Learning}% <-- changed

    begin{tabular}{| l | c |

                     >{centeringarraybackslash}p{8cm}|}

    hline

multicolumn{2}{|c|}{Classification}    &   References  \ hline

multirow{8}{*}{rothead{Supervised Learning}}% <-- changed

% further is the same as in above MWE

and table will looks as follows:
