    tdf#118058 sw, sections in tables: no split for multiple columns
    
    The original use-case was "group a few paragraphs together" for the
    split sections inside tables, i.e. it's safe to not split when the
    section has multiple columns.
    
    And the multiple columns case would mean that we don't find where to put
    the follow section inside a table, resulting in a layout loop.
