org-table-sum

org-table-sum is an interactive autoloaded compiled Lisp function in `org-table.el'.


(org-table-sum &optional BEG END NLAST)

Sum numbers in region of current table column.
The result will be displayed in the echo area, and will be available
as kill to be inserted with C-y.

If there is an active region, it is interpreted as a rectangle and all
numbers in that rectangle will be summed. If there is no active
region and point is located in a table column, sum all numbers in that
column.

If at least one number looks like a time HH:MM or HH:MM:SS, all other
numbers are assumed to be times as well (in decimal hours) and the
numbers are added as such.

If NLAST is a number, only the NLAST fields will actually be summed.
