You may use tabular*, set the tabcolsep to 0pt, and let tabular* calculate the width by using @{extracolsep{fill}}. If you need multi line cells, just change wc{0.025linewidth} to p{0.025linewidth}, and similar for other other length.

documentclass[twocolumn]{article}          % twocolumn

usepackage{array, pdflscape}

begin{document}
begin{landscape}
begin{table*} [!htp]

footnotesize
setlength{tabcolsep}{0pt}

begin{tabular*} {linewidth}{@{extracolsep{fill}}| wc{0.03textwidth}|
                                 *{32}{wc{0.025textwidth}|}
                                wc{0.069textwidth}|}

hline  
A & multicolumn{18}  {c|}   {A} 
  & multicolumn{9}  {c|}   {A}
  & multicolumn{5}  {c|}   {A}
  &Ref

hline
A & 1&2&3&4&5&6&7&8&9&10&11&12&13&14&15&16&17&18&19&20&21&22&23&24&25&26&27&28&29&30&31&32&Ref

hline

end{tabular*}
end{table*}

end{landscape}

end{document}

You need at least one X column:
documentclass[twocolumn]{svjour3}          % twocolumn
usepackage{tabularx,pdflscape}
begin{document}
begin{landscape}
smallnoindent
begin{tabularx}{linewidth}{|X|*{32}{p{0.011textwidth}|}X|}  hline  
A & multicolumn{18}  {m{0.198textwidth}|}   {A} 
  & multicolumn{9}  {m{0.099textwidth}|}   {A}
  & multicolumn{5}  {m{0.055textwidth}|}   {A}
  &Refhline
A & 
1&2&3&4&5&6&7&8&9&10&11&12&13&14&15&16&17&18&19&20&21&22&23&24&25&26&27&28&29&30&31&32&Refhline
end{tabularx}
end{landscape}

end{document}
