Title: BUG: summary2 use float_format

when creating `_simple_tables` setting float_format is ignored
see #1964

However, this is incomplete as fix, since there are three dictionaries in `settings`, that have been appended in different methods or functions.

Should there only be one, or is this on purpose?
