If you must typeset this in math mode, you can use the array
environment as a replacement for tabular.
$$
\begin{array}{lcl}
\bf\text{Name} & \bf\text{Date} & \bf\text{Formula} \\
\text{Newton} & 1687 & F = ma \\
\text{Einstein} & 1905 & E = mc^2
\end{array}
$$
I'm not sure what you mean by embedding fonts in your LaTeX code. To
get bold, use {\bf ...} or \mathbf{...}, for example. For double-
struck characters, use \Bbb{...} or \mathbb{...}. Not sure quite what
you have in mind. Can you be more specific?
