Name of table SE16 uses to save table fields for selection?

Does anyone know the table or tables SE16 uses to store the fields for selection and fields for display?  I know it stores them by table name and user Id.  I have tried to find it using runtime analysis, but just can't seem to find it.  Also, I would prefer finding a FM that reads and update it as well, but just knowing the table name would really help me.

Thanks,

Larry
