How can I reveal one column at a time?

```
\documentclass{beamer}
\usepackage{tabularray}
\usepackage{changepage}
\usepackage{multirow}
\usepackage{tabularx}
\usepackage{makecell}


\begin{document}

	
\begin{frame}{Title}

	\begin{adjustwidth}{-1em}{-1em}
		\begin{tblr}{
				hlines,
				colspec={XXX},
				row{1}={font=\bfseries,halign=c},
				row{2-Z}={font=\small}
			}
			\large Day 1 & \large Day 2 & \large Day 3 \\ 
			\SetColumn{blue7} &  \SetColumn{green7}    & \SetColumn{red7}  \\ 
			 & \\ 
			&  & \\ 
			&  & \\ 
		\end{tblr}
	\end{adjustwidth}

\end{frame}

	
\end{document}

```

I would like just the first column showing in the first transition, the first two in the next and all three in the last. I will have text in the table eventually.

How can you do that?

You could use the same technique as in @Carlatex's answer https://topanswers.xyz/tex?q=2000#a2242

```
\documentclass{beamer}
\usepackage{tabularray}
\UseTblrLibrary{counter}

\begin{document}

\begin{frame}
\frametitle{Title}
\begin{tblr}{
  hlines,
  colspec={X[bg=blue7]X[bg=green7]X[bg=red7]},
  row{1}={font=\bfseries\large,halign=c},
  row{2-Z}={font=\small},
  cells={cmd=\onslide<\arabic{colnum}->}
}
Day 1 & Day 2 & Day 3 \\ 
& & \\ 
& & \\ 
& & \\ 
& & \\ 
\end{tblr}
\end{frame}

\end{document}
```

(if it bothers you that the background and lines are visible from the start, then best remove them. The table will look much better without)
