Customising text in a table

Question

I am new to latex and in a pressing need to quickly design a fine confusion matrix (with text rotation) as in the attached screenshot:

I am not sure how the content can be customised in latex as in the shown table (Predicted column orientation, double-line horizontal line etc).
Any help would be appreciated.
EDIT
I would have love to use @Zarko's answer since I'm using `ieeetran` document class but I encountered an error:
The compiler is having trouble understanding a command you have used. Check that the command is spelled correctly. If the command is part of a package, make sure you have included the package in your preamble using usepackage{...}.

with some options defined in the command appearing in the output:

I suspect that you use ieeetran or similar document class. With employed siunitx package (for S columns), booktabs (for horizontal rules), multirow (for cell with vertical text), and rotating and makecell (for rotate text in the first column) packages:
documentclass{ieeetran}
usepackage{rotating}
usepackage{booktabs, makecell, multirow}
NewExpandableDocumentCommandmcc{O{1}m}
    {multicolumn{#1}{c}{#2}}
usepackage{siunitx}

begin{document}
    begin{table}[ht]
caption{Confusion matrix for SVM using pooled features}
label{tab:confusion}
settowidthrotheadsize{textbf{Predicted}}
    centering

For double lines in tables you can use hhline package.
For rotation of text in tables rotatebox. (explanation see here)
documentclass{article}
usepackage{hhline}
usepackage{booktabs}
usepackage{multirow}
usepackage{adjustbox}
newcommandRotText[1]{rotatebox{90}{parbox{1.9 cm}{raggedright#1}}}
 
begin{document}
    
begin{table}[h]
renewcommand{arraystretch}{1.25}
%caption{Table}
label{tab:my-table}
centering
setlengthdoublerulesep{0.8pt} % distance or the 2 lines in the double line
begin{tabular}{cccccccc}
specialrule{2pt}{1pt}{1pt} % thick line
multicolumn{8}{c}{textbf{Actual}} 
multicolumn{2}{c}{textbf{}}                       & textbf{Bike} & textbf{Car} & textbf{Walk} & textbf{Run} & textbf{Bus} & textbf{Precision}  hline
