如何关闭表格中的竖线

有人知道如何修复右侧的垂直条吗?提前谢谢!

\begin{tabular}{ |p{0.15\linewidth}||p{0.15\linewidth}|p{0.15\linewidth}|p{0.2\linewidth}| p{0.2\linewidth}| }
 \hline
 \multicolumn{5}{|c|}{Project Timeline} \\
 \hline

 \hline
 $I$ is funny  & June 2021    &October 2021&   December 2022 &   May 2022 (if possible)\\
 \hline\\

正如我在评论中所说,您不应该使用,\hline\\而只能使用\hline

关于您的表格,有一些题外话。您没有提供任何有关文档布局的信息,也没有提供此表格如何插入其中。无论如何,看看以下对您的表格的重写是否对您有所帮助:

\documentclass{article}
\usepackage[margin=25mm]{geometry}
\usepackage{ragged2e}
\usepackage{tabularx}  
\newcolumntype{L}[1]{>{\RaggedRight\arraybackslash%
                       \hspace{0pt}\hsize=#1\hsize}X}

\begin{document}
    \begin{table}[ht]
    \setlength\extrarowheight{2pt}
\begin{tabularx}{\linewidth}{|L{0.85}||L{0.85}|L{0.85}|L{1.225}|L{1.225}|} \hline
 \multicolumn{5}{|c|}{Project Timeline} \\
 \hline
Family & First Examples Computed By & All Examples Computed By & Conjectures Proposed By & Proof Completed By\\
 \hline
 $I$ is funny  & June 2021    &October 2021&   December 2022 &   May 2022 (if possible)\\
 \hline
blah blah blah or $5$  & September 2021    &November 2021&   January 2021 &   May 2022 (if possible)\\
\hline
$I$ is angry  & October 2021    &December 2021&   February 2022 &   May 2022 (if possible)\\
 \hline
\end{tabularx}
    \end{table}
\end{document}

现在表格宽度等于\textwidth与其大小无关的宽度(您的宽度不是),单元格中的文本不是对齐的,而是(通过使用包智能地ragged2e)通过新定义的列类型左对齐(这可以简单地改变单元格宽度之间的比率,但是,它们的总和必须是等于列数的整数)。
