# In Mathjax, how do you get a curly bracket (or brace) to span multiple lines?

How do you align items in an array?

\begin{array}{ccc} a & b & c \\ d & e & f \\ g & h & i \end{array}

To do this, you can make use of the array syntax. The letters can either be r, c or l, depending on if you want the text to be right aligned, center-aligned, or left-aligned

 \begin{array}{ccc} a & b & c \\ d & e & f \\ g & h & i \end{array}
