I have posted a question Different width for caption and floatfoot with floatrow (which contains a MWE) regarding setting caption and
\floatfoot width in the
floatrow package, which was answered so wonderfully! I was not sure if proper etiquette is to create a new question although related, so please feel free to let me know if I should have simply added this as a comment in the previous answer.
In any case, I was wondering what the best way to set a custom width of the caption is, with regards to the method used in the previous question. I did some research and found Caption and footnote width with ctable, but it seems to pertain specifically to the
ctable package and environment.
So I was wondering what the best way to obtain a specific width for my caption in the first link would be. I wasn't sure if something like
minipage or such would be a proper solution, or what the best/most proper way to define the width would be.
