 Note, however, that not all features of

-.B @g@tbl

+.B gtbl

 can be wrapped into a macro because

-.B @g@tbl

+.B gtbl

 sees the input earlier than 

 .BR @g@troff .

 For example, number formatting with vertically aligned decimal points

 fails if those numbers are passed on as macro parameters because

 decimal point alignment is handled by

+.B gtbl

 itself: It only sees `\[rs]$1', `\[rs]$2', etc., and therefore can't

 recognize the decimal point.
