I'm looking for a simple, framed, float box-environment that has (or can have by construction) a star equivalent (like figure* or table*) so that it may span both columns in the paracol environment. An enumeration of what I'm looking for:
- Simple environment that may contain text,
- which provides a framed box around that text
- and has a
*equivalent (e.g. figure*) for the purpose of spanning two columns in aparacolenvironment.
Does such an environment exist?
I'm asking this as a means of accomplishing the ultimate goal that motivated two other questions I previously asked:
