I need to keep both a List of Tables and a Table of Figures. However, most
of the figures will simply be software programmer's code shown in a 1-cell
table. When I insert a caption and choose Figure instead of the automatic
Table, it updates all my tables as figures. I can't seem to separate these.

I'd like to either find a way to use a 1-cell table as a figure separate
from all other tables, or find another way to display the code in a box with
gray shading/black border.
