You can quickly sort tables in
org-mode by using
C-c ^ with the point inside a table. You’ll be prompted for a sorting type, where you can choose e.g.
a for alphabetic or
n for numeric. You can use capital letter versions of these options to reverse the sort.
The table is sorted based on the column that the point is in, and from the documentation:
The range of lines is the range between the nearest horizontal separator lines, or the entire table of no such lines exist.
