Strange Line Below Table in Subfigure Graphic

Question

I am relatively new to TeX and I am trying to create a subfigure graphic with 3 figures and one table. I managed to do that beside one problem: Below the table is a strange line (see picture) and I can not find a solution how I could delete it.

Here is my current code:

\begin{landscape}

\begin{figure}[H]

    \centering
    \subfigure{\includegraphics[width=0.49\linewidth]{./graphic1}}
    \subfigure{\includegraphics[width=0.49\linewidth]{./graphic2}}\\[-5ex]

    \begin{subfigure}{\begin{tabular}{|ccc|ccc|}\\[-47ex]

                \hline
                Wert & Modell & Ausfall & HD & PMM & PMM HD\\
                \hline

                KIRate & UM & MAR 2 & 9.6 & 93.4 & 95.3\\
                KIRate & UM & MAR 3 & 0.0 & 58.4 & 64.2\\
                \hline
                KIRate & RM & MAR 2 & 0.0 & 6.1 & 20.5\\
                KIRate & RM & MAR 3 & 0.0 & 0.0 & 0.0\\
                \hline
                KIBreite & UM & MAR 2 & 0.87 & 2.28 & 2.29\\
                KIBreite & UM & MAR 3 & 0.87 & 2.16 & 2.15\\
                \hline
                KIBreite & RM & MAR 2 & 0.87 & 1.20 & 1.20\\
                KIBreite & RM & MAR 3 & 0.86 & 1.03 & 1.09\\
                \hline

            \end{tabular}}
        \end{subfigure}\hspace{0.02\textwidth}
        \subfigure{\includegraphics[width=0.49\linewidth]{./graphic3}}\hspace{-0.11\textwidth}
        \vspace{-2em}
        \caption{Some text} 

    \end{figure} 

\end{landscape}

Here, I found a similar topic: longtable - strange lines at the end of table But unfortunately I can not figure out the problem in my specific case.

How could I delete that line? I guess there must be a very easy solution, which I can not find. Thank you very much in advance!

The culprit is the double backslash starting the table, in \\[-47ex]. It starts a new table line with a vertical bar, then the remaining lines are shifted upwards. — gernot, Mar 05 '17 at 16:19
Thank you @ gernot for the detection of the problem! Originally, I added the \ to be able to insert the [-47ex] afterwards. Without the [-47ex] there appears a big gap between the table and the first graphic. — Joachim Schork, Mar 06 '17 at 07:57
@ Zarko and Kurt, sorry for the missing code. Next time I will add a preamble! — Joachim Schork, Mar 06 '17 at 07:58

Your code snippet is no of big help it only indicate, that you have problems in preamble of your document, which you didn't show (see Mico Comment). So above MWE is based on guessing, what you like to obtain. Spurious line arise because of unusulay coding. In comparison to your code i made the following changes:

wrote consistent preamble, where I uasume, that for landscape fugure with table is better to use sidewaysfigure from rotating package
for subfigures is used subfigure environment determined by package subcaption (your use of subfigure is not consistent, the same time indicate that you probably use obsolete subfigure package)
deleted are all manually positioning of subfigures and sub tables

If you not need subcaptions, than simply delete \caption{...} in subfigures/subtable.

Thank you for the great answer, that worked pretty good! Next time I will add a preamble to my code. — Joachim Schork, Mar 06 '17 at 07:53
