      Link the item headlines in the table to their origins.
 
-- :narrow ::
+- =:narrow= ::
 
      An integer to limit the width of the headline column in the Org

-- :indent ::
+- =:indent= ::
 
      Indent each headline field according to its level.
 
-- :tcolumns ::
+- =:tcolumns= ::

-- :tags ::
+- =:tags= ::
 
      When this flag is non-~nil~, show the headline's tags.
 
-- :properties ::

      inherited.
 
-- :formula ::
+- =:formula= ::
 
      Content of a =TBLFM= keyword to be added and evaluated.  As

      clock table survives updates and is evaluated.

+- =:formatter= ::
 
      A function to format clock data and insert it into the buffer.
