I want to make a table like this table 
I tried this :
\begin{tabular}{ |p{3.7cm}||p{3.7cm}|p{3.7cm}|p{2.9cm}| }
\hline
KeyWords& Google Scholar& IEEEXplore & ScienceDirect\\
\hline
Afghanistan & AF &AFG& 004\\ \hline
Aland Islands& AX & ALA &248\\ \hline
Albania &AL & ALB& 008\\ \hline
Algeria &DZ & DZA& 012\\ \hline
\end{tabular}
As you can see the fields don't have the same height as I want.
