How to add space following individual row in table Latex

Question

I'm trying to add .2cm of space following an individual row in a table in LaTeX. Earlier "\[.2cm]" worked, but since updating my system, I'm no longer getting any spacing difference. Can anyone explain this? Some example code is provided below.

\begin{tabular}[t]{>{\labels[]}llll}
col 1 & col2 & col3 & col4 \\
text & text & text & text \\
text & text & text & text \\[.2cm] 
text & text & text & text \\
text & text & text & text \\
\end{tabular}
