That is, you can share the information about whether the user has taken whatever action you need.

To find out whether a figure has a table on it or not, try something like

handleList = findobj(1, 'type', 'table') 
handleList = findobj(1, 'type', 'uitable')

Not sure which one it is, if it is even any of those, but it might be worth giving it a try.

If a table is not there, handleList should be empty.
