I'm writing my thesis, and I use some acronyms in it.

For example "MDBs" = "Multilateral Development Banks".

Usually, I write "Multilateral Development Banks (MDBs)" the first time I cite it and then use "MDBs".

Now I have the case where the first time I use this acronym is in a table. In the ordinary text following the table I wrote "Multilateral Development Banks (MDBs)", but should I put a footnote also in the table?
