Greek Letters in Latex Table

Question

I have been using online latex editor for generating equations for my blog. I am kind of novice to Latex. Now I want to generate a table for the first time. But when I try to write a greek letter into a table cell I get invalid equation error.

A sample code is:

\begin{tabular}{|l|c|r|} 
\hline
2 & \alpha & 4 \\
\hline
\end{tabular}

This \alpha generates the "invalid equation" error, I want a greek alpha letter there.

Sorry if it is too simple but after half an hour I am still stuck. Thanks in advance...

Answer 1

Table cells are not in math mode. You need to add a math environment around mathematical contents. Try this:

\begin{tabular}{|l|c|r|}
\hline
$2$ & $\alpha$ & $4$ \\
\hline
\end{tabular}
