Are you just using the Data Table from URL Definition for ease of use? If yes I really would suggest again that you use the Data Table from Instance Definition widget instead. I linked a really good article on how to customize that widget in my first post. Having looked at the code for Data Table from URL Definition there appears to no great way to place the filter you are looking for; someone correct me if I am wrong. You would have to edit the Data Table widget and make a conditional checking for if the table name was 'task' then add the encoded query as we discussed. The reason I say it doesnt look easy to configure the URL Definition widget is due to (highlighted in yellow)
you might be able add another line under the orange arrow calling gr.addEncodedQuery(encodedQuery) and pass in the variable as previously mentioned. In my experience using Data Table from Instance Definition is the way to go; especially if this is just being used as a static table. If you have anymore questions I am happy to offer my two cents but I don't have as much experience using Data Table from URL Definition.
