definition. If the cursor is somewhere inside the outline, this command
searches the hierarchy, up from point, for a :COLUMNS:
property that
defines a format. When one is found, the column view table is established
for the tree starting at the entry that contains the :COLUMNS:
property. If no such property is found, the format is taken from the
#+COLUMNS
line or from the variable org-columns-default-format
,
and column view is established for the current entry and its subtree.
