Display configured mock data as a grid

when you are configuring mock data, the complete data set can sometimes become quite cluttered. Also, you cannot immediately see which results are returned by an expression. I would like to see a tab next to the 'column values', or in another place if that makes more sense, with 'data', where the result of the complete mock data set can be displayed. Then we wouldn't have to click back and forth through all the configured rows to see the result of the mock data set and look for where an expression is incorrect or data is wrong, for example.
