## Installation

```bash
# Check if installed
kpsewhich tabularray.sty

# If not found, install:
sudo tlmgr install tabularray
```

## Basic Usage

```latex
\documentclass{article}
\usepackage{tabularray}  % Modern table package

\begin{document}
% Simple table
\begin{tblr}{colspec={ccc}, hlines, vlines}
  Header 1 & Header 2 & Header 3 \\
  Data 1   & Data 2   & Data 3   \\
\end{tblr}
\end{document}
```

______________________________________________________________________

## Quick Reference Card

```latex
% Minimal table
\begin{tblr}{colspec={ccc}}
  A & B & C \\
\end{tblr}

% With all lines
\begin{tblr}{colspec={ccc}, hlines, vlines}
  A & B & C \\
\end{tblr}

% Fixed widths
\begin{tblr}{colspec={Q[2cm] Q[3cm] Q[2cm]}, hlines}
  A & B & C \\
\end{tblr}

% Bold header
\begin{tblr}{
  colspec={ccc},
  row{1}={font=\bfseries}
}
  Header & Header & Header \\
  Data   & Data   & Data   \\
\end{tblr}
```

## Best Practices

1. Use Q[width] for fixed columns instead of p{width}
2. Specify widths explicitly when text might overflow
3. Use X for flexible columns that should expand
4. Style headers with row{1} instead of manual formatting
5. Use colspec for column properties, not inline commands
6. Check package version: `kpsewhich tabularray.sty` (should be recent)
