I would like to show one table row at the time.
With `\pause` it should be easy.
With `tabular`, it works perfectly but, with `tlbr`, it produces a strange output.
```
\documentclass{beamer}
\usepackage{tabularray}
\begin{document}
\begin{frame}{With tabular works}
\begin{tabular}{cc}
first & tabular\pause \\
second & tabular \\
\end{tabular}
\end{frame}
\begin{frame}{With tblr doesn't work}
\begin{tblr}{cc}
first & tblr\pause \\
second & tblr \\
\end{tblr}
\end{frame}
\end{document}
```

One could use the following hacky workaround (for a cleaner solution, please see https://github.com/lvjr/tabularray/issues/226#issuecomment-1086623661):
```
\documentclass{beamer}
\usepackage{tabularray}
\makeatletter
\newcommand{\slideinframe}{\beamer@slideinframe}
\makeatother
\begin{document}
\begin{frame}
\frametitle{With tblr doesn't work}
\begin{tblr}{
vlines = {1-\slideinframe}{solid},
colspec={cc}
}
first & tblr \\
\visible<\value{rownum}->{second} & \visible<\value{rownum}->{tblr}\\
\visible<\value{rownum}->{second} & \visible<\value{rownum}->{tblr}\\
\visible<\value{rownum}->{second} & \visible<\value{rownum}->{tblr}\\
\visible<\value{rownum}->{second} & \visible<\value{rownum}->{tblr}\\
\end{tblr}
\end{frame}
\end{document}
```
Caveat:
the numbers in `1-\slideinframe` might need tweaking depending on the situation. It assumes that a) there are no previous overlays on this slide and b) that each row is uncovered step by step.

Putting together the solution provided by the package author when I opened the issue: https://github.com/lvjr/tabularray/issues/226#issuecomment-1086623661
with samcarter's solution:
https://topanswers.xyz/tex?q=2000#a2241
Here is another solution:
```
\documentclass{beamer}
\makeatletter
\newcommand{\slideinframe}{\beamer@slideinframe}
\makeatother
\usepackage{tabularray}
\UseTblrLibrary{counter}
\begin{document}
\begin{frame}{With tblr does work, too!}
\begin{tblr}{colspec={cc},
vlines = {1-\slideinframe}{solid},
cells={cmd=\onslide<\arabic{rownum}->}}
first & tblr \\
second & tblr \\
\end{tblr}
\end{frame}
\end{document}
```
