代码细节问题很多，比如缺少 booktabs，比如 参数里的宽度 是一个不知道什么东西，改成这样： ```tex \documentclass[review]{elsarticle} \usepackage{booktabs} \usepackage{lineno,hyperref} \modulolinenumbers[5] \usepackage{amssymb} \usepackage{graphicx} \journal{Journal of \LaTeX\ Templates} \bibliographystyle{elsarticle-num} \begin{document} \begin{table} \caption{Key input variables and DCF main values of Scheme 1} \begin{tabular}{\textwidth}{@{} lll@{} } \toprule Variables & Values & Definition/resource\ \midrule CapEx-MGO & 0 & Initial investment using MGO\ Price-MGO & \$570/ton & Using the average price of MGO (Singapore)\ Usage-MGO & 40 000 tons & MGO annual usage\ Discount rate &11\% & Weighted average cost of capital(WACC) is the company’s weighted cost of capital, including all sources of capital: equity and debt.
