我試圖使用表格來顯示一些訊息，但文字直接從頁面上消失。看一看：
\documentclass{article}
\begin{document}
\begin{flushleft}
\begin{enumerate}
\item Rationale/Theoretical Reasoning (Hoe does your lesson target specific features of one or more of the five reform appraoches?)
\vspace{1cm}
\item Materials, Resources, Safety
\begin{itemize}
\item Battery
\item Copper Wire
\item Screw/Bolt
\item Electrical Tape
\item Box Cutter
\item Wire Cutter
\end{itemize}
\vspace{1cm}
\item NYS Learning Standards
\begin{center}
\begin{tabular}{| c | c |}
\hline
Sequence & Performance Indicators\\
\hline
III.6 & A circuit is a closed path in which a current* can exist.\\
\hline
III.8 & Circuit components may be connected in series* or in parallel.* Schematic diagrams are used to represent circuits and circuit elements\\
\hline
III.9 & Moving electric charges produce magnetic fields. The relative motion between a conductor and a magnetic field may produce a potential difference in the conductor\\
\hline
\end{tabular}
\end{center}
\end{enumerate}
\end{flushleft}
\end{document}
請幫忙！
答案1
列l,c,r說明符用於單行單元格。您必須選擇允許文字換行的段落列類型。我建議tabularx您可以設定整體表格寬度的環境。這是一個代碼：
\documentclass{article}
\usepackage{tabularx}
\begin{document}
\begin{flushleft}
\begin{enumerate}
\item Rationale/Theoretical Reasoning (Hoe does your lesson target specific features of one or more of the five reform appraoches?)
\vspace{1cm}
\item Materials, Resources, Safety
\begin{itemize}
\item Battery
\item Copper Wire
\item Screw/Bolt
\item Electrical Tape
\item Box Cutter
\item Wire Cutter
