# How to get multiple multirows in a table?

I want to render a table with results of experiments. There are 6 experiments (multirows) described by 2 columns and each of them is performed 5 times (rows).

My code:

\begin{tabular}{l r | l || r r}
Vzorka & Výskyty & Algoritmus & Porovnania & Prístupy \\ \hline
\multirow{5}{*}{Gabriel} & \multirow{5}{*}{8}
& NAIVE BINARY          & 158   & 44 \& NAIVE BINARY_LCP      & 174 & 92 \& NAIVE INTERPOLATION   & 168 & 78 \& LESS NAIVE BINARY       & 98    & 26 \& LESS NAIVE BINARY_LCP & 124   & 58 \\ \hline
...
\end{tabular}


This code produces what I want only for the first row:

successful rows after the first one are shifted and overlapping the "8" number. Can you please help me?

\begin{tabular}{l r | l || r r}
