[ncl-talk] Remove white-spaces from write_table output

[Rabah Hachelaf]

Hi Mary and Karin,

Adding white-spaces by default is a limitation if we need to write some
data using a FORTRAN format.
We could bypass this "issue" by removing one character starting from the
2nd variable but we would have liked to keep the same format between
FORTRAN and NCL

Regards,

Rabah
