basic table in latex

Here is a quite basic plus table creation in latex

\begin{tabular}{|l|l|l|l|l|l|l|l|}  \hline
& & &\multicolumn{5}{|c|}{Internalsinl}  \\ \cline{4-8}
ID&Art&Test&         aa1,12bb&aa1,100bb&aa1,1ujbb&aa1,1uj0bb&aa1,1ujbb $\cup$  \\
&          &           &       &       &        &         & aa1001,1uj0bb \\ \hline
Axd &Thi s time &Ex spr & hjtp & hjtp & hjtp & hjtp & hjtp  \\ \cline{3-8}

\end{tabular}

• First line {|l ....|} determines the column, possible value "l/r/c", and without "|" means without vertical line
  
• "&" separate each item in column
  
• "cline" line on certain column
  
• "hline" horizontal line entire column
  
• beware of the number of "&" on each line,
  
• every line ends with "\\"
