Answer 1

Há muitas maneiras de colocá-lo em paisagem, mas o seguinte fará pelo menos com que caiba em uma página. (Aliás, também é grande demais para paisagem.)

\documentclass[a4paper,oneside,12pt]{report}
\usepackage{graphics}% for \resizebox

\begin{document}

%\begin{sidewaystable}[h]
\begin{table}[htp]
%\restylefloat{table}
 \centering\small\setlength\tabcolsep{3pt}

%\centering \footnotesize\setlength{\tabcolsep}{0.5pt}
%\toprule
\resizebox{\textwidth}{!}{% fit on page
\begin{tabular}{l@{\hspace{3pt}} *{15}{c}}

%\begin{tabular}{l@{\hspace{1pt}} *{12}{c}}
\hline
\hline

%\bfseries cluster&

Answer 2

Esta é uma solução possível onde os rótulos (1) a (15) são adicionados para liberação. Esta solução pensa que os colegas usuários do CFR e do Torbjorn estão dando a direção certa e, além disso, a lacuna (mostrada por (A), B, C aqui) entre as duas categorias de estudo apresenta problemas. Há um total de 16 colunas e o multicolumnagrupamento também é uma fonte de erro.

Nota: remover (A),B,C resultará na lacuna correta. Aqui eles servem como faróis de referência.

Você poderia fazer isso. Não recomendo, mas é possível.
