Customizing captions of floating environments using the caption package
Axel Sommerfeldt · 2008
The caption package offers customization of captions in floating environments such figure and table and cooperates with many other packages. Please note: Many document classes already have build-in options and commands for customizing captions. If these possibilities are sufficient for you, there is usually no need for you to use the caption package at all. And if you are just interested in using the command \\captionof, loading of the very small capt-of package is usually sufficient.
