你忘记了\caption{...}\\
它就像表格中的多列和一行。
以下只是一个让它变小的想法：
\documentclass[parskip=half]{scrartcl}
\usepackage{longtable,graphicx}
\def\RB#1{\rotatebox{90}{#1}}
\begin{document}
\begin{table}[!htb]
\caption{A Table Depicting the Relationship between Meat, Fruit, Oil}
\resizebox{\linewidth}{!}{\tabcolsep=2pt%
\begin{tabular}{*{16}r p{2cm}}
\RB{Oil (Barrels)} & \RB{Fruit (Ton)} && \RB{Meat (Ton)} & \RB{Fruit (Ton)} && \RB{Meat (Ton)} & \RB{Oil (Barrel)} & \RB{Oil (Barrels)} & \RB{Fruit (Ton)} & & \RB{Meat (ton)} & \RB{Fruit (ton)} & & \RB{Meat (ton)} & \RB{Oil (barrel)} \\
