[Tex/LaTex] Controlling vertical space within a “tabbing” environment

algorithmsspacingtabbing

I'm using the "tabbing" environment to typeset algorithms. Because I'm using math formulas within the algorithms (yes I know about specific packages to do this), the vertical space needs a bit of (manual, case by case) tweaking, yet I have been unable to affect the vertical spacing of individual lines.

Any reference to vertical spacing and "tabbing" I could find were about how to suppress the spacing at the beginning and end of the environment—which is not my concern.

Below is some (I believe) minimal code snippet to reproduce the problem. On my system, this renders as a list of "test" lines, with the spacing always the same everywhere.

\documentclass{article}

\begin{document}

\begin{tabbing}
  \=X \= X \= XXX\= XXX \= XXX\=\kill
  \>\>test\\
  \>\>test\\
  \>\>test\\\vspace{10cm}
  \>\>test\\
  \>\>test\vspace{10cm}\\
  \>\>test\\
  \>\>test\bigskip\\
  \>\>test\\\bigskip
  \>\>test
\end{tabbing}

\end{document}

You can use the optional argument for \\:

\documentclass{article}

\begin{document}

\begin{tabbing}
  \=X \= X \= XXX\= XXX \= XXX\=\kill
  \>\>test\\
  \>\>test\\
  \>\>test\\[1cm]
  \>\>test\\
  \>\>test\\
  \>\>test\\[2ex]
  \>\>test\\
  \>\>test\\
  \>\>test
\end{tabbing}

\end{document}
