Align the entire table developed by tabularray to the left

horizontal alignmenttablestabularray

I have a table developed by tabularray, but I could not find in the documentation how to align the entire table to the left to let the entire table being centered again.

This is the code:

\documentclass{article}
\usepackage{tabularray}
\usepackage[table]{xcolor}
\begin{document}


\begin{tblr}{
colspec={cccccccc},
rowspec={Q[gray!20]Q[]Q[gray!10]Q[]Q[gray!10]Q[]Q[gray!10]Q[]}, 
vline{2-8} = {0-1}{0.3pt,gray!50},
vline{2-8} = {2-7}{0.3pt,gray!30},
hline{1,2,8} = {0.1pt,azure5}}
Dataset  & \# clusters & \# Train neurons & \# Test neurons & \# Extra neurons & Architectures & Train loss & Test loss\\
1  & Beta & Gamma & Alpha & Beta & Gamma & Beta & Gamma\\
2  & Beta & Gamma & Alpha & Beta & Gamma & Beta & Gamma\\
3  & Beta & Gamma & Alpha & Beta & Gamma & Beta & Gamma\\
4  & Beta & Gamma & Alpha & Beta & Gamma & Beta & Gamma\\
5  & Beta & Gamma & Alpha & Beta & Gamma & Beta & Gamma\\
6  & Beta & Gamma & Alpha & Beta & Gamma & Beta & Gamma\\

\end{tblr}

Your table is too large to be shown in the same line so I have two solutions for you :

Reduce the size of the table like this

\documentclass{article}
\usepackage[table]{xcolor}
\usepackage{tabularray}
\usepackage{graphicx}
\begin{document}
\scalebox{0.7}{
\begin{tblr}{
colspec={cccccccc},
rowspec={Q[gray!20]Q[]Q[gray!10]Q[]Q[gray!10]Q[]Q[gray!10]Q[]}, 
vline{2-8} = {0-1}{0.3pt,gray!50},
vline{2-8} = {2-7}{0.3pt,gray!30},
hline{1,2,8} = {0.1pt,azure5}}
Dataset  & \# clusters & \# Train neurons & \# Test neurons & \# Extra neurons & Architectures & Train loss & Test loss\\
1  & Beta & Gamma & Alpha & Beta & Gamma & Beta & Gamma\\
2  & Beta & Gamma & Alpha & Beta & Gamma & Beta & Gamma\\
3  & Beta & Gamma & Alpha & Beta & Gamma & Beta & Gamma\\
4  & Beta & Gamma & Alpha & Beta & Gamma & Beta & Gamma\\
5  & Beta & Gamma & Alpha & Beta & Gamma & Beta & Gamma\\
6  & Beta & Gamma & Alpha & Beta & Gamma & Beta & Gamma\\

\end{tblr}}

\end{document}

Change the borders of the page :

\documentclass{article}
\usepackage[table]{xcolor}
\usepackage{tabularray}
\usepackage[a4paper,bindingoffset=0.2in,%
left=0.1in,right=0.5in,top=0.6in,bottom=0.5in,%
footskip=.1in]{geometry}
\begin{document}
\begin{tblr}{
colspec={cccccccc},
rowspec={Q[gray!20]Q[]Q[gray!10]Q[]Q[gray!10]Q[]Q[gray!10]Q[]}, 
vline{2-8} = {0-1}{0.3pt,gray!50},
vline{2-8} = {2-7}{0.3pt,gray!30},
hline{1,2,8} = {0.1pt,azure5}}
Dataset  & \# clusters & \# Train neurons & \# Test neurons & \# Extra neurons & Architectures & Train loss & Test loss\\
1  & Beta & Gamma & Alpha & Beta & Gamma & Beta & Gamma\\
2  & Beta & Gamma & Alpha & Beta & Gamma & Beta & Gamma\\
3  & Beta & Gamma & Alpha & Beta & Gamma & Beta & Gamma\\
4  & Beta & Gamma & Alpha & Beta & Gamma & Beta & Gamma\\
5  & Beta & Gamma & Alpha & Beta & Gamma & Beta & Gamma\\
6  & Beta & Gamma & Alpha & Beta & Gamma & Beta & Gamma\\

\end{tblr}

\end{document}

Just use:

\raggedright

right after \begin{document}

The flushleft environment effectively sets text in a ragged right list environment. It is defined as:

\def\flushleft{\trivlist \raggedright\item\relax} 
\def\endflushleft{\endtrivlist}

The \raggedright command does the actual work:

\def\raggedright{%
   \let\\\@centercr\@rightskip\@flushglue \rightskip\@rightskip
   \leftskip\z@skip
   \parindent\z@}

Setting text this way will lead to some ugly looking lines. The ragged2e package provides the \RaggedRight command (and corresponding) FlushLeft environment that solves some of these problems. I would recommend using it instead of just \raggedright.

To see the differences between \raggedright and \RaggedRight here's a small sample document:

\documentclass{article}
\usepackage[english]{babel}
\usepackage[margin=1in]{geometry}
\usepackage{hyphenat}
\usepackage{ragged2e}
\usepackage{blindtext}

\begin{document}
\begin{minipage}[t]{.4\textwidth}
\textbf{raggedright with no hyphenation}\par
\raggedright
\blindtext
\end{minipage}
\hfill
\begin{minipage}[t]{.4\textwidth}
\textbf{RaggedRight with hyphenation}\par
\RaggedRight
\blindtext
\end{minipage}
\end{document}

output of code

Both \raggedright and \RaggedRight set the paragraph indent to zero. With ragged2e this is controllable with the length \RaggedRightParindent which can be set to equal the regular \parindent in the following way:

\setlength{\RaggedRightParindent}{\parindent}

To do this with regular \raggedright you could do the following:

\usepackage{etoolbox}
\newlength{\rrindent}
\setlength{\rrindent}{\parindent}
\apptocmd{\raggedright}{\setlength{\parindent}{\rrindent}}{}{}

Tabularray: align tabular with text

From tabularray version 2022A (2022-03-01), \firsthline and \lasthline commands are deprecated in favor of baseline=T and baseline=B specifications. You can write baseline option as either an inner specification or an outer specification. And when baseline=T/B is an outer specification, you can omit the key name and write the value only:

\documentclass{article}
\usepackage{tabularray}
\usepackage{array}
\begin{document}

\section{Tabularray}

Test 1
\begin{tblr}[T]{vlines, colspec={c}}
\hline
  Test 2 \\
\hline
  Test 3 \\
\hline
\end{tblr}
Test 1
\begin{tblr}[B]{vlines, colspec={c}}
\hline
  Test 2 \\
\hline
  Test 3 \\
\hline
\end{tblr}

\section{Tabular}

Test 1
\begin{tabular}[t]{|c|}
\firsthline
  Test 2 \\
\hline
  Test 3 \\
\hline
\end{tabular}
Test 1
\begin{tabular}[b]{|c|}
\hline
  Test 2 \\
\hline
  Test 3 \\
\lasthline
\end{tabular}

\end{document}

But you can still roll back to version 2021Q with \usepackage{tabularray}[=v2021], so that you can use \firsthline and \lasthline commands in tblr environment. The usage is the same as in tabular environment:

\documentclass{article}
\usepackage{tabularray}[=v2021]
\usepackage{array}
\begin{document}

\section{Tabularray}

Test 1
\begin{tblr}[t]{vlines, colspec={c}}
\firsthline
  Test 2 \\
\hline
  Test 3 \\
\hline
\end{tblr}
Test 1
\begin{tblr}[b]{vlines, colspec={c}}
\hline
  Test 2 \\
\hline
  Test 3 \\
\lasthline
\end{tblr}

\section{Tabular}

Test 1
\begin{tabular}[t]{|c|}
\firsthline
  Test 2 \\
\hline
  Test 3 \\
\hline
\end{tabular}
Test 1
\begin{tabular}[b]{|c|}
\hline
  Test 2 \\
\hline
  Test 3 \\
\lasthline
\end{tabular}

\end{document}
