Hey I noticed that some formulas do not with in tables.
Seems like code blocks don’t either 
I noticed this too 
would be nice to have this functionality.
Very little formatting works in tables - you can’t have lists or images either. One way around is to use LaTeX arrays:
$$
\begin{array}{|l|l|}
\hline
\textbf{Constant} & \textbf{Estimate} \\
\hline
\rho_{c,0} & 10^{-26}\text{ kg m}^{-3} \\
\hline
\Omega_{\Lambda,0} & 0.7\pm 0.05 \\
\hline
\Omega_{b,0}\text{(baryons)} & 0.045 \pm 0.005 \\
\hline
\Omega_{r,0}\text{(CMB)} & 5\times 10^{-5} \\
\hline
\Omega_\text{star light} & 10^{-6} \\
\hline
\Omega_\text{dust emission} & 10^{-6} \\
\hline
\end{array}
$$
That’s sad 
I hope this can be fixed at some point.
