Valid parameters include:
:query An Org QL query expression in either sexp or string
form.
:columns A list of columns, including `heading', `todo',
`property', `priority', `deadline', `scheduled'.
Each column may also be specified as a list with the
second element being a header string. For example,
to abbreviate the priority column: (priority \"P\").
For certain columns, like `property', arguments may
be passed by specifying the column type itself as a
list. For example, to display a column showing the
values of a property named \"milestone\", with the
header being abbreviated to \"M\":
((property \"milestone\") \"M\").
:sort One or a list of Org QL sorting methods
(see `org-ql-select').
:take Optionally take a number of results from the front (a
positive number) or the end (a negative number) of
the results.
:ts-format Optional format string used to format
timestamp-based columns.
For example, an org-ql dynamic block header could look like:
