Doubt regarding uploading Tables and Figures for the accepted manuscript
In my opinion, the guideline regarding tables is outdated, and one can safely ignore it. If you submit your manuscript in LaTeX, put your tables in the main text. This is a current mainstream in (STEM-related) journals, and it is good to delicately push IEEE towards it. In case if they insist on doing this the other way (which I seriously doubt), you can address the questions to their production team.
