表格底部边框仅显示在一列上

Question

该表格仅最后一列有底部边框tabular且浮动table。

我真的不知道为什么。

此外，我无法判断这是否是布局文本的最佳方式。

\begin{table}[h]
    \small
    \noindent\makebox[\textwidth]{
        \begin{tabular}{|p{5cm}|p{1.4cm}|p{5cm}|p{1cm}|p{3.5cm}|}
            \hline

            More/Less(IV) of                           & Leads to    & More/Less of (DV)                                    & Due to & Reason                                                      \\
            \hline
            An increase in worldwide internet coverage & resulted in & an increase of video games with online functionality & due to & an increasing number of customers with internet connections
            \hline
        \end{tabular}
    }
\end{table}
