Numbers: Is it possible to import animated gifs? I wanted to know if there is any chance to run an animated gif or somekind of video within a numbers table?
Yes on macOS you can add movies and animated gifs into a Numbers table. By simply drag and drop movies and/or animated gifs into Numbers.   

I dropped it next to the table. After it was imported I positioned it on top of the right cell. Not in the cell but on top of the cell.
