Adding Table Column Fields

This simple routine design to emulate EXCEL feature of adding fields in the column.
Routine works in AutoCAD R2005 with Tables. It will add-up fields in table columns (similar to
a picture above). If information in table fields is in decimal units set LUNITS=2 (left side of the table above)
and LUNITS=4 if it is in architectural units (right side of the table above) - prior to using routine.
Load and run routine, Select table, type number of column you wish to add-up,
pick the insertion point for a string of text with result. Routine will use current layer and text settings.
