Specify locations of headers/rows
----------------------------------

With known locations of headers, rows, or cells, you can configure a :class:`.TATRFormattedTable` of your choice. 
One option is through the :meth:`.TATRFormattedTable.from_dict()` method. 
To see the necessary format, check out `github <https://github.com/conjuncts/gmft/blob/main/test/refs/tatr_tables.info>`_.

This example is taken from the `internal test for serialization <https://github.com/conjuncts/gmft/blob/main/test/test_serial.py>`_.

    table = TATRFormattedTable.from_dict(tiny_info, page)

These are the labels for bboxes: (the source location is :attr:`.TATRFormattedTable.id2label`)

.. code-block:: python
    
    id2label = {
        0: 'table',
        1: 'table column',
        2: 'table row',
        3: 'table column header',
        4: 'table projected row header',
        5: 'table spanning cell',
        6: 'no object',
    }

The ``fctn_results`` field of a FormattedTable can also be specified with the appropriate structure. 
Changing the bboxes in this way should affect subsequent calls to :meth:`.FormattedTable.df()`.
