Math & Science ⇒ Neaten up an Array

[Philosophaie]

This array is all bunched together.
Is there any way of having the columns grouped together and many spaces between columns?
Also if possible put vertical lines on each side.

Code: Select all

\begin{align*}
        C_x = \begin{array}{c}%
                \hat{i} \hat{j} \hat{k}\\
                X1 Y1 Z1\\
                X2 Y2 Z2\\
        \end{array}\\
\end{align*}

[Johannes_B]

Are you looking for a matrix?

Code: Select all

\documentclass[12pt]{article}
\usepackage{mathtools}
\begin{document}
\begin{align*}
	C_x = \begin{vmatrix}%
		\hat{i}& \hat{j}& \hat{k}\\
		X1&Y1&Z1\\X2&Y2&Z2\\
	\end{vmatrix}
\end{align*}
\end{document}

Please always post complete and compilable examples. Makes testing much easier.

By the way, you could post a hand drawn image (Paint?) or a photo of a hand made drawing to explain the desired output, if you like. Posts can have image attachments. Sometimes a picture says more than words. Just to mention the possibility.
