How to rotate a table in "tabularray" environment with "\begin{turn}{180}" in LaTeX?

Question

I want to rotate a table of tabularray environment by rotating package in LaTeX. When I tested, I found that there is an error about tabularray. For example:

\documentclass{article}
\usepackage{tabularray}
\usepackage{rotating} % <-- HERE
\begin{document}
\begin{turn}{180}
blabla dummy text
\begin{table}
        \begin{talltblr}[
            caption={1},
            label={tab:1}
            ]{
                colsep=0.3pt
            }
            Hello
        \end{talltblr}
\end{table}
\end{turn}
\end{document}

And the error is:

Is there a way to combine rotation with tabularray?

Answer 1

Just remove the table environment.

%! TEX program = lualatex
\documentclass{article}
\usepackage{tabularray}
\usepackage{rotating} % <-- HERE
\begin{document}
\begin{turn}{180}
blabla dummy text
        \begin{talltblr}[
            caption={1},
            label={tab:1}
            ]{
                colsep=0.3pt
            }
            Hello
        \end{talltblr}
\end{turn}
\end{document}

Explanation: looking up what the error message means you can easily come across ! LaTeX Error: Not in outer par mode ...

then it's written in e.g. LaTeX unofficial reference manual that table is a floating environment. So you can't use table inside turn.

Alternatively, you can turn the table itself while keeping it floating by putting the turn environment inside the table environment.

%! TEX program = lualatex
\documentclass{article}
\usepackage{tabularray}
\usepackage{rotating} % <-- HERE
\begin{document}
blabla dummy text
\begin{table}
\begin{turn}{180}
        \begin{talltblr}[
            caption={1},
            label={tab:1}
            ]{
                colsep=0.3pt
            }
            Hello Hello Hello Hello
        \end{talltblr}
\end{turn}
\end{table}
\end{document}

Another alternative is to put both the text and the table inside the floating environment.
