One of the easiest ways to vary the line width in your tables is with the booktabs package, which provides lines (or rules) of predefined width. The lines *\toprule*, *\midrule*, and *\bottomrule* are great to use for a table. Each rule can also be specified, locally or globally, for your own weighting preferences.

**Table using hline:**

```
\begin{document}
\begin{tabular}{ccc}
\hline
1 & 2 & 3 \\
\hline
4 & 5 & 6 \\
\hline
7 & 8 & 9 \\
\hline
\end{tabular}
\end{document}
```

**Output:**

**Table using booktabs:**

```
usepackage{booktabs}
\begin{document}
\begin{tabular}{ccc}
\toprule
1 & 2 & 3 \\
\midrule
4 & 5 & 6 \\
\midrule
7 & 8 & 9 \\
\bottomrule
\end{tabular}
\end{document}
```
