Column Selection using a Disconnected table

Hello,

I am having trouble with creating some sort of selector that will display each different type of date period and their corresponding sums in a single table. I am not too sure whether that is possible through the use of a disconnected table or if I must display the values in seperate tables. 

I have been trying to use some sort of Switch statement to display the date periods and the premium values but am unable to get it to work.

Any help with or guidance would be much appreciated. 

Thanks in advance.
