I have the following table:

   documentclass[a4paper,preprint,aps,

                   unsortedaddress]{revtex4}

    usepackage[top=2.5cm,bottom=2.5cm,

                left=3.5cm,right=2.5cm]{geometry}

    usepackage{longtable,array,booktabs}



    ifdefinedmc

       renewcommand{mc}{multicolumn}

    else

       newcommand{mc}{multicolumn}

    fi



    begin{document} 



        setlengthLTleft{-3.0cm}

        setlengthLTright{-2.0cm}



        scriptsize



    begin{longtable}{ l r @{--} p{1.3cm} >{centering}p{2.6cm} 

                       *{4}{p{1.25cm}} p{2.1cm}}               

    %% headers and footers



    caption{Table} \ 

    hlinehline

    endfirsthead



    mc{9}{c}{tablename thetable -- emph{Continued from previous page}} \ 

    hline

    aaaaaaaaaaaaaaaaaaaaaaaa & mc{2}{c}{bbb--ccc} & ddd & eee & fff & ggg & hhh & iii \

    hline

    endhead



    hline

    mc{9}{r}{emph{Continued on next page}} \

    endfoot



    hlinehline

    endlastfoot



    %% body of table



        aaaaaaaaaaaaaaaaaaaaaaaa & mc{2}{c}{bbb--ccc} & ddd & eee & fff & ggg & hhh & iii \

    aaaaaaaaaaaaaaaaaaaaaaaa & bbb & ccc & ddd & eee & fff & ggg & hhh & iii \

    aaaaaaaaaaaaaaaaaaaaaaaa & bbb & ccc & ddd & eee & fff & ggg & hhh & iii \

    aaaaaaaaaaaaaaaaaaaaaaaa & bbb & ccc & ddd & eee & fff & ggg & hhh & iii \



    end{longtable}

    end{document}

which I would like to shift to the left by setting setlengthLTleft{-3.0cm}
and setlengthLTright{-2.0cm}. Furthermore, I have to apply scriptsize for the table. However, none of these commands are working with revtex4. Could you please provide a solution to this problem? (This question is the same as in LTleft, LTright, and scriptsize not working with revtex4, but I cannot sign up with that username.)
If it is not possible, an alternative solution would also be useful for me. For this case, I attached the first page of my real table.

The revtex4 classes (by the way, the current version is revtex4-2) issue table@hook when a longtable is being built. The standard value for table@hook is small.

usepackage{longtable,array,booktabs}



newcommand{mc}{multicolumn}



makeatletter

newenvironment{xlongtable}[1]

 {appdeftable@hook{#1}longtable}

 {endlongtable}



begin{document}



begin{xlongtable}{scriptsize}{

  l r @{--} p{1.3cm} >{centering}p{2.6cm} 

  *{4}{p{1.25cm}} p{2.1cm}

}

%% headers and footers



caption{Table} \

toprule

endfirsthead



mc{9}{c}{tablename thetable -- emph{Continued from previous page}} \ 

midrule

aaaaaaaaaaaaaaaaaaaaaaaa & mc{2}{c}{bbb--ccc} & ddd & eee & fff & ggg & hhh & iii \

aaaaaaaaaaaaaaaaaaaaaaaa & bbb & ccc & ddd & eee & fff & ggg & hhh & iii \

aaaaaaaaaaaaaaaaaaaaaaaa & bbb & ccc & ddd & eee & fff & ggg & hhh & iii \



end{xlongtable}



end{document}

I removed the conditional redefinition of mc: if the command is defined, it would be a mistake to redefine it without knowing where it comes from.

Setting LTleft and LTright requires a hack. Be aware that such tricks can be worthy a rejection, as they change the shape of documents from what revtex people expect.

end{xlongtable}



end{document}

Here I used showframe just to make the page boundaries clear.
