I am trying to implement (and build upon) your video using a spreadsheet to create new slides in keynote. I already have the slides in place, but I would like to know if there is a script I could write to change the value in a cell with the same table name on each slide.

I'm not going to be of much direct help there. That video is from 2 years back and I haven't worked with JavaScript to generate Keynote slides since. I think you can only set the contents of the default items on a slide, but changing other items might not work.
If there is a way to do it, you'll find it by carefully combing through the documentation. Run the Script Editor app, then choose Window, Library. Double-click on Keynote in the Library window to open the documentation for it. Be sure to switch from AppleScript to JavaScript at the top.
