format-table: add ability to set cell attributes within table_add_many()

Browse Source 
table_add_many() is so much shorter and easier to read than
table_add_cell() with its accessors. Let's teach table_add_many() more
tricks, so that reverting to table_add_cell() is not needed that often
anymore.
