Adding £ to the front of one column of a matrix table

Hi all,

Is there a way of adding a £ sign to the front of the right hand column?

I can see there is an option to do this when using a constant sum type matrix table, however I don't need it on the left column, just the right.
Is this something I can do with Java? If so, could someone direct me to the right bit of code please?

Much appreciated!
