How to Add vertical line in table Latex

Question

I have this sheet of latex code.

\begin{table}[c]

\caption{\textbf{the results of analysis of variance (One Way ANOVA) 
  for the differences in the responses of the study sample according
  to different classes.}}
\bigskip
\centering

\begin{tabular}  {|M{4.5cm}|M{1.5cm}|M{1.5cm}|M{1.5cm}|M{1.75cm}|M{1.5cm}|M{2.5cm}|}
\hline
 \textbf{} & \textbf{Variance}         
 &\textbf{Sum of the squares }  & \textbf{Degrees of Freedom } &
 \textbf{Average Squares} &\textbf{P Value} &\textbf{Statistical  significance } \\ 
\hline

\multirow{3}{*}{\makecell{Q11.2}} & UK &122 & 0.14 & 0.348 &
\multirow{3}{*}{\makecell{0.978}  }  &  \multirow{3}{*}
{\makecell{0.329}}\\  \cline{2-5}
             & SA  & 224 & 0.10 & 0.304
             \\  \cline{2-5}
             & SA  & 224 & 0.10 & 0.304
             &&    \\ \hline

\end{tabular}
\end{table}

I get this output :

I don't know how to fill empty vertical lines!

What's wrong with my code?

Solution

When using \multirow, you have to include empty cells in each row that you want the multirow to span. This means that the line

    & SA  & 224 & 0.10 & 0.304 \\

actually should read as

    & SA  & 224 & 0.10 & 0.304 & & \\

This should give the desired result!

Two additional remarks:

• You might want to reconsider the usage of the \makecell-command, which is in my opinion not necessary.
• It was not easy to answer your question as you did not provide the following defintion, which you have probably used: \newcolumntype{M}[1]{>{\centering\arraybackslash}m{#1}}

Here is the entire code i used

\documentclass[a4paper,11pt]{article}
\usepackage[a4paper,text={160mm,255mm},centering,headsep=5mm,footskip=10mm]{geometry}
\usepackage[english]{babel}
\usepackage[utf8x]{inputenc}
\usepackage{array}
\usepackage{multirow}

\newcolumntype{M}[1]{>{\centering\arraybackslash}m{#1}}

\begin{document}
\begin{table}[c]

\begin{tabular}{|M{4.5cm}|M{1.5cm}|M{1.5cm}|M{1.5cm}|M{1.75cm}|M{1.5cm}|M{2.5cm}|}
\hline
    & \textbf{Variance} & \textbf{Sum of the squares} & 
        \textbf{Degrees of Freedom } & \textbf{Average Squares} &
        \textbf{P Value} & \textbf{Statistical  significance } \\ 
\hline
  \multirow{3}{*}{Q11.2} & UK &122 & 0.14 & 0.348 & 
        \multirow{3}{*}{0.978} & \multirow{3}{*}{0.329}\\  
\cline{2-5}
             & SA  & 224 & 0.10 & 0.304 & & \\
\cline{2-5}
             & SA  & 224 & 0.10 & 0.304 & & \\ 
\hline
\end{tabular}
\end{table}
\end{document}
