The link didn't lead to anywhere. Is this a fraud?

You're right. How could I miss *?

If I try to typeset

\documentclass{article}
\usepackage[inline]{enumitem}
\begin{document}
\begin{enumerate*}[label=\arabic)]
\item ohai
\item yes
\end{enumerate*}
\end{document}

I see the following error:

ERROR: Missing number, treated as zero.

I felt that egreg's answer was overly complex in the preamble.
It should take a while to understand what the preamble of egreg's answer contains.

Sir, I cannot find Enrico on that web page.

I asked a question on http://tex.stackexchange.com/q/286883/82730.
A few valid answers came up, but they all seemed overly complex for a beginner or suboptimal.

Can anyone think of a concise and elegant way to typeset an abbreviated truth table?

Great.

Thanks. That clarifies things.

It seems to make no difference in visual output. Why do people add @{}?

What is \thetab? Ah, it's defined in preamble.
Why do you insert @{} in preamble of tabularx? It doesn't seem to make a difference.
