我对以下代码感到厌倦，但总是得到大小不等的列{我需要相同宽度的列（2 端）。
\begin{table}[h]
\resizebox{\textwidth}{!}{%
\begin{tabular}{|p{8cm}|l|l|l|l|l|l|l|l|l|l|l|l|}
\hline
\textbf{Subject} & \multicolumn{4}{l|}{\textbf{First year}} & \multicolumn{4}{l|}{\textbf{Second year}} & \multicolumn{4}{l|}{\textbf{Third year}} \\ \hline

\end{table}
答案1
使用tabularx环境而不是仅仅使用环境来tabular从所有中受益\textwidth，同时具有相同宽度的列。
