Is there any way to specify the format of the output from debug.trace function?

What I want to be able to do is to print out variables and have them appear in fixed fields.

Example: if I=5, j=100 and I call debug.trace(i + j,1)

then what I get is

5 100

but what I would want is

5 100

i.e. let the space taken up by the variables be some fixed size.
