Examples
========

Write a Markdown table
----------------------

.. code:: python

import pytablewriter

writer = pytablewriter.MarkdownTableWriter()
writer.table_name = "example_table"
writer.header_list = ["int", "float", "str", "bool", "mix", "time"]
writer.value_matrix = [
[0, 0.1, "hoge", True, 0, "2017-01-01 03:04:05+0900"],
[2, "-2.23", "foo", False, None, "2017-12-23 45:01:23+0900"],
[3, 0, "bar", "true", "inf", "2017-03-03 33:44:55+0900"],
[-10, -9.9, "", "FALSE", "nan", "2017-01-01 00:00:00+0900"],
]

writer.write_table()

.. code::

# example_table
int|float|str |bool | mix | time
--:|----:|----|-----|-------:|------------------------
0| 0.10|hoge|True | 0|2017-01-01 03:04:05+0900
2|-2.23|foo |False| |2017-12-23 12:34:51+0900

Write a table with JavaScript format (as a nested list variable definition)
---------------------------------------------------------------------------

.. code:: python

import pytablewriter

writer = pytablewriter.JavaScriptTableWriter()
writer.table_name = "example_table"
writer.header_list = ["int", "float", "str", "bool", "mix", "time"]
writer.value_matrix = [
[0, 0.1, "hoge", True, 0, "2017-01-01 03:04:05+0900"],

Write a table using multibyte character
---------------------------------------

You can use multibyte character as table data.

.. code:: python

import pytablewriter

writer = pytablewriter.RstSimpleTableWriter()
writer.table_name = "生成に関するパターン"
writer.header_list = ["パターン名", "概要", "GoF", "Code Complete[1]"]
writer.value_matrix = [
["Abstract Factory", "関連する一連のインスタンスを状況に応じて、適切に生成する方法を提供する。", "Yes", "Yes"],
["Builder", "複合化されたインスタンスの生成過程を隠蔽する。", "Yes", "No"],
["Factory Method", "実際に生成されるインスタンスに依存しない、インスタンスの生成方法を提供する。", "Yes", "Yes"],
["Prototype", "同様のインスタンスを生成するために、原型のインスタンスを複製する。", "Yes", "No"],
["Singleton", "あるクラスについて、インスタンスが単一であることを保証する。", "Yes", "Yes"],
]
writer.write_table()

Write a table from ``pandas.DataFrame`` instance
------------------------------------------------


.. code:: python

import pandas as pd
import pytablewriter
from StringIO import StringIO

csv_data = StringIO(u""""i","f","c","if","ifc","bool","inf","nan","mix_num","time"
1,1.10,"aa",1.0,"1",True,Infinity,NaN,1,"2017-01-01 00:00:00+09:00"
2,2.20,"bbb",2.2,"2.2",False,Infinity,NaN,Infinity,"2017-01-02 03:04:05+09:00"
3,3.33,"cccc",-3.0,"ccc",True,Infinity,NaN,NaN,"2017-01-01 00:00:00+09:00"
""")
df = pd.read_csv(csv_data, sep=',')

writer = pytablewriter.MarkdownTableWriter()
writer.from_dataframe(df)
writer.write_table()


.. code::

i | f | c | if |ifc|bool | inf |nan|mix_num | time
--:|---:|----|---:|---|-----|--------|---|-------:|-------------------------
1|1.10|aa | 1.0|1 |True |Infinity|NaN| 1|2017-01-01 00:00:00+09:00
2|2.20|bbb | 2.2|2.2|False|Infinity|NaN|Infinity|2017-01-02 03:04:05+09:00
