    MoinMoin - macro to collect data from definition lists from pages
    into a databrowser widget table

    will create a on default a table row for every subpage of the current page
    and a table column for each key and fills the cells with data from each
    key value pair of a definition list. You can change the search_expression
    keyword to any regex you want. All attributes to the macro are optional.
    You can give as an attribute to the macro the name of the template page
    the definition list page depends on.
    You can also list the desired keys with the attribute column_heading.
    In the latter case the table colunms will have the same order as the keys
    The macro can finally also use the definition list from another pagename.
    By setting a parser one can use a different parser than moinmoin's default
    like for example wikimarkup.
    With the attribute filter_selection you can use the filter method of the
    databrowser widget (this needs javascript enabled).
    By using a different filter_column_value than the default empty one,
    eg. name:: Cohen you get only rows shown where that name was found.
    If you want to rename your column titles later on that can be done
    by adding the dictionary keyword pointing on a page with aliases
    for your labels as definition list.
    With sort_column_name given as list you can sort the table by
    multiple columns. And sort_reverse=True makes it reverse.
    By using the keyword transpose the table is shown transposed.
    Until transpose is not part of the databrowser widget itselfs we
    don't support every feature of this macro e.g. filter_selection.
