    [html-table][API] deprecate gnc:html-table-append-column!
    
    This function is inefficient. Each column appended will require
    scanning every row of existing html-table, scanning the row's elements
    and appending the desired data.

commit ef8f8bdcd79a78ca4cd87e7c05eb546a585b2abd

    Reports: don't use gnc:html-table-append-column!
    
    This function is inefficient. Each column appended will require
    scanning every row of existing html-table, scanning the row's elements
    and appending the desired data.
    
    It is much more efficient to build a html-table by append rows instead
    -- html-table rows are stored in reverse, and each appended row is
    built using (cons newrow existing-rows).
