我使用下表，在Deliverable和Projected Deadline之间没有垂直线，我无法触及它的底部。我在这里使用tabularx包。
\begin{tabularx}{\linewidth}{|X|X|X|}
\hline
\rowcolor[HTML]{C0C0C0}
\textbf{Deliverable} & \textbf{Projected Deadline} & \textbf{Final Deadline} \\ \hline
Project Proposal & 26th October 2016 & 28th October 2016 \\ \hline
Literature and Technology Survey & 18th November 2016 & 25th November 2016 \\ \hline
Demonstration of Progress & 6th February 2017 & 20th February 2017 \\ \hline
Completed Project & 21st April 2017 & 5th May 2017\\ \hline
\caption{Deliverables}
\label{tbl:Deliverables}
\end{tabularx}
我在Google上发现的很多东西都会导致使用multirows时出错，但我在这里不使用它们是值得一提的。
它也出现在平台前左上角的下表中。
\begin{tabularx}{\linewidth}{|X|X|}
\hline
\rowcolor[HTML]{C0C0C0}
\textbf{Platform} & \textbf{Programming Languages} \\ \hline
Android & Java \\ \hline
iOS & Objective-C \\ \hline
Symbian & C++ \\ \hline
BlackBerry & Java \\ \hline
Bada & C++ \\ \hline
Windows Phone & C\# \\ \hline
\caption{Table showing platform’s programming languages (Holzinger, Slany and Treitler, 2012)\cite{Holzinger2012}.}
\label{tbl:Platform Programming Languages}
\end{tabularx}
有什么建议吗？
