How to add a caption under simple table

[mxa]

Traditionally the captions works just like this:

\begin{table}
    \centering
    <table data>
    \caption{The caption}\label{thelabel}
\end{table}

with tabularray I will get errors if I mimic the same syntax.

\begin{tblr}
    \centering
    <table data>
    \caption{The caption}\label{thelabel}
\end{tblr}

The tabularray documentation only covers captions for long tables, if I apply this style to normal tables it isn't shown

\begin{tblr}[caption = {The Caption}]
    \centering
    <table data>
\end{tblr}

Solution:

\begin{table}
    \begin{center}
        \begin{tblr}
        <table data>
        \end{tblr}
    \caption{The caption}\label{thelabel}
    \end{center}
\end{table}

\end{centering} should be \end{center}

Better solution:

\begin{table}[!htpb]
  \centering
  \begin{tblr}{lcr}
    1 & 2 & 3 \\
    3 & 4 & 5
  \end{tblr}
  \caption{The caption}
  \label{thelabel}
\end{table}

or

\SetTblrTemplate{head}{empty}
\DefTblrTemplate{foot}{default}{
  \UseTblrTemplate{caption}{default}
}
\begin{table}[!htpb]
  \centering
  \begin{talltblr}[
    caption = {The caption},
    label = {thelabel},  
  ]{lcr}
    1 & 2 & 3 \\
    3 & 4 & 5
  \end{talltblr}
\end{table}

In the second snippet, use of \UseTblrTemplate{caption} is incomplete. Should be \UseTblrTemplate{caption}{default}.

Originally reported by @MicPellegrino in #186 (comment).

Fixed. I typed the comment on my phone and didn't compile it.

That would be good to add to the documentation.

Hi,
None of these solutions seem to work on Overleaf.
The caption doesn't shown when using \begin{center} or \centering, whereas the second solution of @lvjr just gives me an error:

Missing \endcsname inserted.
<to be read again> 
                   \group_end: 
l.312   \end
            {talltblr}
The control sequence marked <to be read again> should
not appear between \csname and \endcsname.
Use of \??? doesn't match its definition.
<argument> \???  
                 ! LaTeX Error: Erroneous variable \l__tblr_template_caption...
l.312   \end
            {talltblr}
If you say, e.g., `\def\a1{...}', then you must always
put `1' after `\a', since control sequence names are
made up of letters only. The macro here has not been
followed by the required stuff, so I'm ignoring it.
Extra \endcsname.
\exp_args:Nc ...>\exp_after:wN #1\cs:w #2\cs_end: 
                                                  
l.312   \end
            {talltblr}
I'm ignoring this, since I wasn't doing a \csname.

There was an incomplete use of \UseTblrTemplate. It takes two mandatory arguments so should be used as \UseTblrTemplate{caption}{default}, not \UseTblrTemplate{caption}. I've added a reply #186 (reply in thread).

BTW the output is still not good enough, when the table is narrow.

Full example

\documentclass{article}
\usepackage{tabularray}

\begin{document}
\SetTblrTemplate{head}{empty}
\DefTblrTemplate{foot}{default}{%
  \UseTblrTemplate{caption}{default}%
}
\begin{table}[!htpb]
  \centering
  \begin{talltblr}[
    caption = {The caption},
    label = {thelabel},  
  ]{lcr}
    1 & 2 & 3 \\
    3 & 4 & 5
  \end{talltblr}
\end{table}
\end{document}
