We can use a Button component with a script on it to refresh the component with the query binding on it. Typically the button is placed close by the query bound component, and will say something like "Refresh Data". The script is actually fairly simple, and can be placed on the actionPerformed event of the Button.
Add in this script, which will force the Table's data property to refresh.
# Will force the Power Table's Data property to run the query again. system.db.refresh(event.source.parent.getComponent('Power Table'), "data")
