It tells you that _ can only be used in math mode for subscripts. If 
you want the _ to print, you have to use it with \: sv\_gravity (also 
with #: \#). This typesets fine:

\begin{tabular}{|r|l|}
\hline
   Set Gravity & sv\_gravity  \\
  Shows FPS Rate & cl\_showfps 1 \\
  Shows all available levels & Maps * \\
  Load specified map & map nameofmap.bsp \\
  Walk through walls  & Noclip \\
  NPCs can't see you, won't fire at you, etc. & notarget \\
  Spawn a buggy & Impulse 82 \\
  Give yourself all weapons & Impulse 101 \\
  God mode & God \\
  First person view & Firstperson \\
  Third person view & Thirdperson (causes general movement wonkiness) \\
  See through walls & Mat\_depthbias\_normal 1 \\
  Change difficulty level  & Skill \# (1, 2, or 3) \\
  \hline
  \end{tabular}
\end{document}

Best regards,

Axel
