How to place a landscape table on a portrait page without clearing the current page?

Question

Following the post https://tex.stackexchange.com/questions/19017/how-to-place-a-table-on-a-new-page-with-landscape-orientation-without-clearing-t/453774?noredirect=1#comment1141155_453774

I would like to enter a landscape oriented table inside a portrait page without the table to be floating. Since, if it remains floating it drops in another page. I used the code of the attached link:

    \documentclass[a4paper,12pt,oneside]{report}
    \usepackage{fullpage}  % megalitara margin gia tex
    \usepackage{algorithm} % gia tis listes graph and diagram

    \usepackage{amsmath,eqparbox,xparse}  %equations in curled brackets are centered
    \usepackage{amsfonts}
    \usepackage{mathtools}
    \usepackage{indentfirst}
    \usepackage{tabularx}
    \usepackage{longtable}
    \usepackage{threeparttable}
    \usepackage{lscape}
    \usepackage{scalefnt}
    \usepackage{graphicx}
    \usepackage{float}
    \usepackage{rotating}
    \usepackage{setspace}
    \usepackage{geometry}
    \usepackage{booktabs}

    \usepackage{afterpage}


            \begin{document}
blah blah blah blah blah blah blah blah blah
blah blah blah blah blah blah blah blah blah
blah blah blah blah blah blah blah blah blah
blah blah blah blah blah blah blah blah blah
blah blah blah blah blah blah blah blah blah
blah blah blah blah blah blah blah blah blah
blah blah blah blah blah blah blah blah blah
blah blah blah blah blah blah blah blah blah
            \afterpage{%
                \clearpage% Flush earlier floats (otherwise order might not be correct)
                \thispagestyle{empty}% empty page style (?)
                \begin{landscape}% Landscape page
                \begin{table}
                    \centering % Center table
        \resizebox{1.5\textwidth}{!}{
         \begin{threeparttable}
           \begin{tabular}{llll}
                        A & B & C & D \\


         \end{tabular}
         \begin{tablenotes}[para,flushleft]
              \small
         \item Notes:
            \end{tablenotes}
          \end{threeparttable}
        }
        \end{table}
                \end{landscape}
                \clearpage% Flush page
            }
            \end{document}

but the table drops in another page. Then, I tried by adding \begin{table}[H] ...\end{table} but it only resulted in dropping the table even further and leaving a blank page.

If you don't want the tabular material to fload, don't use a table float object. Instead, embed the threeparttable environment in a \rotatebox{90}{...} directive, and place the whole thing inside a center environment.

Of course, if you don't need a caption, you should omit the \captionof instruction.
