How to Create Tables with MathJax/LaTeX

[Eli]

We can easily create tables, such as this one,

\[
\begin{array}{|c|c|c|}
\hline
\text{Set} & \text{Operation} & \text{Identity} \\
\hline
\mathbb{Z} & + & 0 \\
\hline
\mathbb{Q} & + & 0 \\
\hline
\mathbb{R} & + & 0 \\
\hline
\mathbb{Z} & \times & 1 \\
\hline
\mathbb{Q} & \times & 1 \\
\hline
\mathbb{R} & \times & 1 \\
\hline
\end{array}
\]

by using LaTeX/MathJax.

The code that produces this table is:

Code: [Select all] [Expand/Collapse]

1. \[
2. \begin{array}{|c|c|c|}
3. \hline
4.  \text{Set} & \text{Operation} & \text{Identity} \\
5. \hline
6.   \mathbb{Z} & + & 0 \\
7. \hline
8.   \mathbb{Q} & + & 0 \\
9. \hline
10.   \mathbb{R} & + & 0 \\
11. \hline
12.   \mathbb{Z} & \times & 1 \\
13. \hline
14.   \mathbb{Q} & \times & 1 \\
15. \hline
16.   \mathbb{R} & \times & 1 \\
17. \hline
18. \end{array}
19. \]

Enjoy.
