[Tex/LaTex] Table – remove row lines in column to furthest right

Question

How do I remove row lines in the column to furthest to the right.
I have seen examples where they do it the left. I would like the "powers" from the table here to be on the right side instead of the left.

I have the following code:

\documentclass[a4paper,oneside,11pt]{memoir}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage{multirow}
\begin{document}
\renewcommand{\arraystretch}{1.5}%controls the space between the rows
\begin{table}[h!]
    \begin{center}
            \begin{tabular}{ | l | l | l | l |}
            \hline
            \textbf{header one} & \textbf{header two} & \textbf{header three} & \textbf{header four}\\ \hline
             r1c1 & r1c2 & r1c3 &  \multirow{4}{*}{ no row lines in the first four rows}\\ \hline
            r2c1 & r2c2 & r2c3 & \\ \hline
            r3c1 & r3c2 & r3c3 &\\ \hline
            r4c1 & r4c2 & r4c3 &\\ \hline
            r5c1 & r5c2 & r5c3 &\\ \hline
            r6c1 & r6c2 & r6c3 &\\ \hline
            r7c1 & r7c2 & r7c3 &\\ \hline
            \end{tabular}
        \caption{my caption}
        \label{tab:test}
    \end{center}
\end{table}
\end{document}

The text "no row lines in the first four rows" should have… well no row lines – it should be one "big box" :o)
All help is greatly appricated!

Use

\cline{1-3}

in rows 2-4 instead of \hline

% arara: pdflatex
\documentclass{article}
\usepackage{multirow}
\begin{document}
\renewcommand{\arraystretch}{1.5}%controls the space between the rows
\begin{table}[h!]
    \begin{center}
            \begin{tabular}{ | l | l | l | l |}
            \hline
            \textbf{header one} & \textbf{header two} & \textbf{header three} & \textbf{header four}\\ \hline
            r1c1 & r1c2 & r1c3 &  \multirow{4}{*}{ no row lines in the first four rows}\\ \cline{1-3}
             r2c1 & r2c2 & r2c3 & \\ \cline{1-3}
             r3c1 & r3c2 & r3c3 &\\\cline{1-3}
            r4c1 & r4c2 & r4c3 &\\ \hline
            r5c1 & r5c2 & r5c3 &\\ \hline
            r6c1 & r6c2 & r6c3 &\\ \hline
            r7c1 & r7c2 & r7c3 &\\ \hline
            \end{tabular}
        \caption{my caption}
        \label{tab:test}
    \end{center}
\end{table}
\end{document}

Further enhancements to your table can be made by employing the booktabs package, and also noting the answers from

• Should I use center or centering for figures and tables?
• Why should a table caption be placed above the table?
• Why not use vertical lines ('|') in a tabular?
