TABLE DataType in SmartDashboard

Hi -

Our team is trying to write a SmartDashboard widget that instead of using a single value, uses a combination of two values. I was hoping that I could use the TABLE DataType to pass the two values in key-value pairs. Is this possible?

If not, do we have to use a custom Data Packet from the cRIO? If so, can someone give me a pointer to an example project showing how to do this?
