我怀疑您正在寻找类似下表的内容：

\documentclass{article}
\usepackage{booktabs, tabularx}% new
\newcolumntype{L}{>{\raggedright\arraybackslash}X}% new
\usepackage{rotating}

\usepackage{showframe}% only for show page layout
\renewcommand*\ShowFrameColor{\color{red}}

\begin{document}
\begin{sidewaystable}[htbp]
\setlength\tabcolsep{4pt}
    \centering
    \caption{Add caption}
    \begin{tabularx}{\textheight}{l % table width is equal text height
                                  >{\hsize=0.8\hsize}L% new column type
                                  >{\hsize=1.2\hsize}L
                                  >{\hsize=1.2\hsize}L
                                  >{\hsize=0.8\hsize}L
                                  l}
