How to focus parts of table on a beamer

Question

I have a table that contains lots of number on it. I want to use it in a beamer presentation and I wonder whether it is possible to focus different regions at different slides. This is the code I use for creating the table:

\documentclass{article}
\usepackage{booktabs,caption}

\begin{document}
\begin{table}
\captionsetup{font=small,skip=0.333\baselineskip}
\caption*{Data statistics Treebanks} 
\medskip
\setlength\tabcolsep{0pt}
\begin{tabular*}{\textwidth}{@{\extracolsep{\fill}}
    *{2}{l*{5}{r}}}

ir &     &   &    &     &     \\
\bottomrule
\end{tabular*}
\end{table}
\end{document}

It creates the following table:

So, I want to focus on lets say here in one slide:

And this part in another slide:

Is there a way to do that like this ?

with tikzmark library? search for question with this tag. here is many similar question ... — Zarko, May 26 '18 at 17:50
Yes, with \framezoom. (Or with the spy library in TikZ.) — , May 26 '18 at 17:50

The focus could be a color background ?

\documentclass[xcolor=table]{beamer}
\usepackage[size=custom,width=5,height=5,scale=.5,debug]{beamerposter}
\def\grco{}\def\reco{}
\begin{document}

\begin{frame}

\only<2,4>{\def\grco{\rowcolor{green!30}}}
\only<3,4>{\def\reco{\rowcolor{red!30}}}

\begin{tabular}{llll}
    11 & 12 & 13 & 14\\\grco
    21 & 22 & 23 & 24\\
    31 & 32 & 33 & 34\\\reco
    41 & 42 & 43 & 44\\
\end{tabular}
\end{frame}
\end{document}

I also wonder weather is it possible to highlight background as in the first screenshot I shared in my question? I mean half of the two rows (consecutive or not) the half of the lines that starts with ar and bg – zwlayer May 27 '18 at 18:34

@zwlayer You can use \cellcolor instead of \rowcolor in the definition of \grco, for instance, then use in every \grco highlighted cell, e.g., \grco 11 & \clco 12 & 12 & 14 \\ .... – Fran May 27 '18 at 19:53

A rather simple way is to use the \framezoom command.

The second slide will then be

If you remove the \only thingy, the last third slide will be zoom of the relevant part.

If you don't want to guess the coordinates and/or not zoom, you could do as @Zarko suggests, namely draw the boundary with TikZ.
