  LABEL is a string used in #+COLUMNS definition describing the
  summary type.  It can contain any character but \"}\".  It is
  case-sensitive.

  SUMMARIZE is a function called with two arguments.  The first
  argument is a non-empty list of values, as non-empty strings.
  The second one is a format string or nil.  It has to return
  a string summarizing the list of values.

  COLLECT is a function called with one argument, a property
  name.  It is called in the context of a headline and must
  return the collected property, or the empty string.  You can
  use this to only collect a property if a related conditional
  properties is set, e.g., to return VACATION_DAYS only if
  CONFIRMED is true.

Note that the return value can become one value for an higher
order summary, so the function is expected to handle its own
output.

Types defined in this variable take precedence over those defined
in `org-columns-summary-types-default', which see."

    List of tags to exclude from column view table.

`:format'

    When non-nil, specify the column view format to use.

`:hlines'

    When non-nil, insert a hline before each item.  When
    a number, insert a hline before each level inferior or equal
    to that number.

`:indent'

    When non-nil, indent each ITEM field according to its level.

`:match'

    When set to a string, use this as a tags/property match filter.

`:maxlevel'

    When set to a number, don't capture headlines below this level.

`:skip-empty-rows'

    When non-nil, skip rows where all specifiers other than ITEM
    are empty.

`:vlines'

    When non-nil, make each column a column group to enforce
    vertical lines."
