-# tableformatter
+tableformatter: tabular data formatter
+======================================
+tableformatter is a tabular data formatter allowing printing from both arbitrary tuples of strings or object inspection.
+It converts your data into a string form suitable for pretty-printing as a table.  The goal is to make it quick and easy
+for developers to display tabular data in an aesthetically pleasing fashion.  It provides a simple public API, but allows
+fine-grained control over almost every aspect of how the data is formatted.
+
+Main Features
+-------------
+- Easy to display simple tables with just one function call when you don't need the fine-grained control
+- Fine-grained control of almost every aspect of how data is formatted when you want it
+- Tables with column headers
+- Flexible grid style
+- Transposed tables with rows and columns swapped
+- Colored output using either [colorama](https://github.com/tartley/colorama) or [colored](https://github.com/dslackw/colored)
+- Good unicode support including for characters which are more than 1 visual character wide
+- Support for Python 3.4+ on Windows, macOS, and Linux
+
+Installation
+============
+```Bash
+pip install tableformatter
+```
+
+Dependencies
+------------
+``tableformatter`` requires that at least one of the following two modules are installed to support table colors:
+* [colorama](https://github.com/tartley/colorama)
+* [colored](https://github.com/dslackw/colored)
+
+**pip** will treat ``colorama`` as a dependency and install if it isn't already installed.  However, if ``colored`` is
+installed, then it will be used instead of ``colorama``.
+
+
+Usage
+=====
+For simple cases, you only need to use a single function from this module: ``generate_table``.  The only required argument
+to this function is ``rows`` which is an Iterable of Iterables such as a list of lists or another tabular data type like 
+a 2D [numpy](http://www.numpy.org) array.  ``generate_table`` outputs a nicely formatted table:
+
+```Python
+>>> from TableFormatter import generate_table
+
+>>> rows = [('A1', 'A2', 'A3', 'A4'),
+...         ('B1', 'B2\nB2\nB2', 'B3', 'B4'),
+...         ('C1', 'C2', 'C3', 'C4'),
+...         ('D1', 'D2', 'D3', 'D4')]
+>>> print(generate_table(rows))
+╔════╤════╤════╤════╗
+║ A1 │ A2 │ A3 │ A4 ║
+║ B1 │ B2 │ B3 │ B4 ║
+║    │ B2 │    │    ║
+║    │ B2 │    │    ║
+║ C1 │ C2 │ C3 │ C4 ║
+║ D1 │ D2 │ D3 │ D4 ║
+╚════╧════╧════╧════╝
+```
+
+Column Headers
+--------------
+The second argument to ``generate_table`` named ``columns`` is optional and defines a list of column headers to be used.
+
+```Python
+>>> cols = ['Col1', 'Col2', 'Col3', 'Col4']
+>>> print(generate_table(rows, cols))
+╔══════╤══════╤══════╤══════╗
+║ Col1 │ Col2 │ Col3 │ Col4 ║
+╠══════╪══════╪══════╪══════╣
+║ A1   │ A2   │ A3   │ A4   ║
+║ B1   │ B2   │ B3   │ B4   ║
+║      │ B2   │      │      ║
+║      │ B2   │      │      ║
+║ C1   │ C2   │ C3   │ C4   ║
+║ D1   │ D2   │ D3   │ D4   ║
+╚══════╧══════╧══════╧══════╝
+```
+
+Grid Style
+----------
+The third argument to ``generated`` table named ``grid_style`` is optional and specifies how the table lines are drawn.
+
+Supported grid sytles are:
+
+* **AlternatingRowGrid** - generates alternating black/gray background colors for rows to conserve vertical space (defalt)
+* **FancyGrid** - fancy table with grid lines dividing rows and columns
+* **SparseGrid** - sparse grid with no lines at all to conserve both vertical and horizontal space
+
+```Python
+>>> from TableFormatter import FancyGrid
+
+>>> print(generate_table(rows, grid_style=FancyGrid))
+╔════╤════╤════╤════╗
+║ A1 │ A2 │ A3 │ A4 ║
+╟────┼────┼────┼────╢
+║ B1 │ B2 │ B3 │ B4 ║
+║    │ B2 │    │    ║
+║    │ B2 │    │    ║
+╟────┼────┼────┼────╢
+║ C1 │ C2 │ C3 │ C4 ║
+╟────┼────┼────┼────╢
+║ D1 │ D2 │ D3 │ D4 ║
+╚════╧════╧════╧════╝
+```
+
+Transposed Tables
+-----------------
+Normally the "rows" are displayed left-to-right and "columns" are displayed up-to-down.  However, if you want to transpose
+this and print "rows" up-to-down and "columns" left-to-right then that is easily done using the fourth (optional) argument
+to ``generate_table``:
+
+```Python
+>>> print(generate_table(rows, cols, transpose=True))
+╔══════╦════╤════╤════╤════╗
+║ Col1 ║ A1 │ B1 │ C1 │ D1 ║
+║ Col2 ║ A2 │ B2 │ C2 │ D2 ║
+║      ║    │ B2 │    │    ║
+║      ║    │ B2 │    │    ║
+║ Col3 ║ A3 │ B3 │ C3 │ D3 ║
+║ Col4 ║ A4 │ B4 │ C4 │ D4 ║
+╚══════╩════╧════╧════╧════╝
+```
