How can I make a truth table?

Question

For some questions and answers - I would have liked to make a truth table.

Is there a way to make a truth table OR generally any table?

Answer 1

Yes, tables are possible with MathJax. Here's an example, taken from Mathematics.SE:

$$ \begin{array}{c|lcr} n & \text{Left} & \text{Center} & \text{Right} \\ \hline 1 & 0.24 & 1 & 125 \\ 2 & -1 & 189 & -8 \\ 3 & -20 & 2000 & 1+10i \end{array} $$

This table was created with the following MathJax code:

$$
\begin{array}{c|lcr}
n & \text{Left} & \text{Center} & \text{Right} \\
\hline
1 & 0.24 & 1 & 125 \\
2 & -1 & 189 & -8 \\
3 & -20 & 2000 & 1+10i
\end{array}
$$

So, here's a simple truth table example:

$$ p \land q \\ \begin{array}{c|c} p & q & p \land q \\ \hline T & T & T \\ T & F & F \\ F & T & F \\ F & F & F \\ \end{array} $$

$$
p \land q \\
\begin{array}{c|c}
p & q & p \land q \\ \hline
T & T & T \\
T & F & F \\
F & T & F \\
F & F & F \\
\end{array}
$$

Answer 2

Doorknob's answer is perfect, but I would like to point to an easy-alternative (useful in some cases): Use Windword/Excel/whatever to create your table. Do a quick screen-shot (CTRL + Print) and cut out the table from the image (to keep file-size small.) Then upload as an image.

(Disadvantages, of course, no copy&paste of the content for readers and not so easy to correct.)
