[Tex/LaTex] Booktabs and longtable – strange spaces between lines

booktabslongtabletables

I needed to make some horizontal table lines bold so I used booktabs package. However if I use \toprule command to make line bold I get strange outcome – there are some spaces between bold line and vertical table lines (please take a look at screen )

code used to generate table looks this way 

    \begin{longtable}{|c|c|c|c|c|c|c|c|c|}
\caption{Wyniki rozpoznawania obrazów dla obrazu zapytania 022\_0007.jpg oraz kategorii $budda$}
\label{tab:budda}
\\
\toprule
\multicolumn{2}{|c|}{\textbf{Obraz zapytanie}} & \multicolumn{3}{|c|}{\textbf{Obraz przetwarzany}} & \multicolumn{4}{|c|}{\textbf{Wynik}} \\
\toprule
\textbf{Nazwa} & \textbf{N} & \textbf{Katalog} & \textbf{Nazwa} & \textbf{N} & \textbf{ $J_{b}$} & \textbf{$J_{a}$} & \textbf{Czas[s]} & \textbf{Gęstość} \\ \hline
...
..
..
\end{longtable}

PS
Is it possible to make horizontal lines bold ??

EDIT
I decied to resign from booktabs and I used solution presented in here
LaTeX tables: How do I make thicker or thinner horizontal lines (typically \hline)? (pluton answer)
now I have a horizontal bold lines and I also managed to make vertical lines bold. The problem however is horizontal line length. My table's length is a bit bigger than length of page (from one margin to another) and I think it makes the horizontal lines look like that
enter image description here

Is it possible to somehow adjust this command

    \def\hlinewd#1{%
\noalign{\ifnum0=`}\fi\hrule \@height #1 %
\futurelet\reserved@a\@xhline}

so that it adjust length of the bolded line to the length of the table

Here is compilable code snipet

Best Answer

I think I finally found a solution for making booktabs and hrules work so that is why I make an answer to my own question I created my own command 

\newcommand{\mytoprule}{\specialrule{2pt}{0em}{0em}}
\newcommand{\mybottomrule}{\specialrule{2pt}{0em}{0em}}

and now everyting looks fine.
