"""
Provides a simple table class.  A SimpleTable is essentially
a list of lists plus some formatting functionality.

Dependencies: the Python 2.5+ standard library.

Installation: just copy this module into your working directory (or
   anywhere in your pythonpath).

Basic use::

   mydata = [[11,12],[21,22]]  # data MUST be 2-dimensional
   myheaders = [ "Column 1", "Column 2" ]
   mystubs = [ "Row 1", "Row 2" ]
   tbl = SimpleTable(mydata, myheaders, mystubs, title="Title")
   print( tbl )
   print( tbl.as_csv() )

A SimpleTable is inherently (but not rigidly) rectangular.
You should create it from a *rectangular* (2d!) iterable of data.
Each item in your rectangular iterable will become the data
of a single Cell.  In principle, items can be any object,
not just numbers and strings.  However, default conversion
during table production is by simple string interpolation.
(So you cannot have a tuple as a data item *and* rely on
the default conversion.)

A SimpleTable allows only one column (the first) of stubs at
initilization, concatenation of tables allows you to produce tables
with interior stubs.  (You can also assign the datatype 'stub' to the
cells in any column, or use ``insert_stubs``.) A SimpleTable can be
concatenated with another SimpleTable or extended by another
SimpleTable. ::

    table1.extend_right(table2)
    table1.extend(table2)


A SimpleTable can be initialized with `datatypes`: a list of ints that
provide indexes into `data_fmts` and `data_aligns`.  Each data cell is
assigned a datatype, which will control formatting.  If you do not
specify the `datatypes` list, it will be set to ``range(ncols)`` where
`ncols` is the number of columns in the data.  (I.e., cells in a
column have their own datatype.) This means that you can just specify
`data_fmts` without bothering to provide a `datatypes` list.  If
``len(datatypes)<ncols`` then datatype assignment will cycle across a
row.  E.g., if you provide 10 columns of data with ``datatypes=[0,1]``
then you will have 5 columns of datatype 0 and 5 columns of datatype
1, alternating.  Corresponding to this specification, you should provide
a list of two ``data_fmts`` and a list of two ``data_aligns``.

Cells can be assigned labels as their `datatype` attribute.
You can then provide a format for that lable.
Us the SimpleTable's `label_cells` method to do this.  ::

    def mylabeller(cell):
        if cell.data is np.nan:
            return 'missing'

    mytable.label_cells(mylabeller)
    print(mytable.as_text(missing='-'))


Potential problems for Python 3
-------------------------------

- Calls ``next`` instead of ``__next__``.
  The 2to3 tool should handle that no problem.
  (We will switch to the `next` function if 2.5 support is ever dropped.)
- Let me know if you find other problems.

:requires: Python 2.5.1+
:note: current version
:note: HTML data format currently specifies tags
:todo: support a bit more of http://www.oasis-open.org/specs/tr9503.html
:todo: add labels2formatters method, that associates a cell formatter with a
       datatype
:todo: add colspan support to Cell
:since: 2008-12-21
:change: 2010-05-02 eliminate newlines that came before and after table
:change: 2010-05-06 add `label_cells` to `SimpleTable`
