LaTex: Table numbering begins at 2

Question

My table numbering is not working correctly. I have defined continuous numbers like this:

\usepackage{chngcntr}
\counterwithout{table}{chapter}

which works fine, but for some reason the numbering starts at 2. Only if I place the table at the very start of my document, it begins at 1. Look at this:

\begin{document}
% Deckblatt
\begin{spacing}{1}
    \input{ads/deckblatt}
\end{spacing}
\newpage
\begin{table}
\begin{center}
\begin{tabular}{ c c c }
 cell1 & cell2 & cell3 \ 
 cell4 & cell5 & cell6 \

 cell7 & cell8 & cell9

\end{tabular}
\end{center}
\caption{Test\label{tab:table-test}}
\end{table}
...
\end{document}

It results in Table 2 on page 2 after the cover sheet:

However, if I move the table before the cover sheet, it becomes table 1 (in the center of the page):

So I thought the code in \input{ads/deckblatt} is causing this, however its content doesn't seem to make any changes to numberings:

\begin{titlepage}
    \begin{longtable}{p{.4\textwidth} p{.4\textwidth}}
      {\includegraphics[width=6cm]{images/logo.png}} & 
      {\includegraphics[height=2.6cm]{images/dhbw.png}}
    \end{longtable}
    \enlargethispage{20mm}
    \begin{center}

    \vfill
    \begin{spacing}{1.2}
    \begin{tabbing}

        \textbf{Gutachter}             \>  \gutachter
    \end{tabbing}
    \end{spacing}
\end{titlepage}

Why does the table numbering start at 2 and how can I prevent this from happening? In case thats relevant, I am using documentclass scrreprt.

Answer 1

longtable implements its own captioning command, which allows the table number and caption be printed on every page. To make this work longtable increments the table counter.

(Try putting a table before and after the title page. You will probably see that the first table before is Table 1, and the table after is Table 3 [skipping 2 which is the longtable].)

Why are you using longtable anyways? The pair of logos shouldn't break across page boundaries. You can easily typeset the pair of logos without using any table environment.

Edit: In view of the fact that this is a provided template, the easiest workaround is to just \setcounter{table}{0} after you input your title page.
