[Tex/LaTex] Incomplete vertical line while creating a table

rulestables

My code is as below. Last column line is splitted when I leave space between the rows. How can I get a solid vertical line? Please reply

\begin{table}[h!]
        \caption{\textbf{$\alpha=10; U=1; q_u=10; q^{*}=0.3; K_0=0.41; \mu_1=\mu_2=0.5; G_m=0.1$
        }}
        \begin{center}
            \begin{tabular}{|p{4cm}|p{5cm}|p{5cm}|} \hline
                    \hspace{4cm} {\textbf{Applied Pre-stress}} & \textbf{Equivalent Shear Modulus , $G_e$ , considering Confinement effect} &\textbf{Equivalent Shear Modulus , $G_e$ , without considering Confinement effect}\\ \hline
                    0 & 0.318921 & 0.32016 \\ & \\
                    0.2 & 0.932458 & 0.935286\\ & \\
                    0.4 &  1.473396 & 1.476634 \\ & \\
                    0.6 & 1.997815 & 2.003647\\ & \\
                    0.8 & 2.517339 & 2.524832\\ & \\
                    1.0 & 3.033942 & 3.043077 \\ \hline
            \end{tabular}
                    \label{t2}
        \end{center}
\end{table}

Don't use line breaks (& \\) in tables.

\documentclass{article}

\def\VSpace{1.0ex}%  Adjust this to what spacing you want
\begin{document}
\begin{table}[h!]
        \caption{\textbf{$\alpha=10; U=1; q_u=10; q^{*}=0.3; K_0=0.41; \mu_1=\mu_2=0.5; G_m=0.1$
        }}
        \begin{center}
            \begin{tabular}{|p{4cm}|p{5cm}|p{5cm}|} \hline
                    \hspace{4cm} {\textbf{Applied Pre-stress}} & \textbf{Equivalent Shear Modulus , $G_e$ , considering Confinement effect} &\textbf{Equivalent Shear Modulus , $G_e$ , without considering Confinement effect}\\ \hline
