How to properly align numbers enclosed in parentheses?

I want to align positive numbers and negative numbers enclosed in parentheses using CSS to achieve the following result:

 431,000
 (26,000)
  94,000
 (57,000)

Using text-align:right; on table cells returns the following result instead:

 431,000
(26,000)
  94,000
(57,000)

But this is imperfect.

Is there an easy way to do this in such a way that parentheses have not effect on the alignment.

I want to align the numbers so that commas are on top of each other.

Thanks!!
