'RRV_______________.__' adding leading spaces in the amount column

     Hi All,

I have used 'RRV_______________.__' for displaying '-' sign at the left of the amount column which is coming correct, but now issue is that its adding unnecessary spaces between '-' sign and the amount.

How should I remove those spaces.

its showing like this: -            372.38

but it want like this : -372.38

Thanks and regards,
