Hi,
The measures are accuracy of placement and height and spin. You could put targets on the table and a string across above the net to see if they are hitting their target and keeping the ball low under the string.
Spin can be measured by the flight of the ball and the path it takes on the second, third and subsequent bounces. You could track the path of the ball after service.
