At this moment you can do autorefresh only one way. Create Boolean tag, bind this tag to the output of the Script object - Multivibrator. Value of this tag will be changed from the FALSE to TRUE. Bind this tag to the one of the property of the Table (for example Visibility) and make the condition of the property always TRUE (for example for boolean value !=2). Table will be refresh every time when tag's value will be changed from FALSE to TRUE.
I think in the next version we'll add some property in History Table to make it more comfortable to set up conditions of refresh.
