Smartdashboard types and values

[Varriount]

My team is trying to display a list of subsystem data (like the speed of a motor) on the smartdashboard. To do this, we have overridden the subsystem class's getTable functions and variables to add extra values to the subsystem table. The tables are updated every .02 seconds (or thereabout) via a thread, however the smartdashboard will only show the command running. Is there something that needs to be changed in order for the dashboard to show multiple values?
