``margin`` attribute can be available for all of the text format writer classes.
Write a GitHub Flavored Markdown (GFM) table
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
If you set ``flavor`` keyword argument of ``MarkdownTableWriter`` class to ``"github"`` or ``"gfm"``, the writer will output markdown tables with GitHub flavor.
GFM can apply some additional styles to tables such as ``fg_color`` (text color).
:Sample Code:
.. code-block:: python
from pytablewriter import MarkdownTableWriter
from pytablewriter.style import Style
writer = MarkdownTableWriter(
column_styles=[
Style(fg_color="red"),
Style(fg_color="green", decoration_line="underline"),
],
headers=["A", "B"],
value_matrix=[
["abc", 1],
["efg", 2],
],
margin=1,
flavor="github",
enable_ansi_escape=False,
)
writer.write_table()
Rendered results can be found at `here `__
Apply styles to GFM table with programmatically
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Applying style filters to GFM allows for more flexible style settings for cells.

:Sample Code:
.. code-block:: python
import pandas as pd
import pytablewriter as ptw
def main():
writer = ptw.MarkdownTableWriter(table_name="add_index_column")
writer.from_dataframe(
pd.DataFrame({"A": [1, 2], "B": [10, 11]}, index=["a", "b"]),
add_index_column=True,
)
writer.write_table()

Get rendered tabular text as str
----------------------------------
``dumps`` method returns rendered tabular text.
``dumps`` only available for text format writers.
:Sample Code:
.. code-block:: python
import pytablewriter as ptw
def main():
writer = ptw.MarkdownTableWriter(
headers=["int", "float", "str", "bool", "mix", "time"],
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"],

|-10|-9.90| |False| NaN|2017-01-01 00:00:00+0900|
Configure table styles
------------------------
Column styles
~~~~~~~~~~~~~~~
Writers can specify
`Style `__
for each column by ``column_styles`` attribute of writer classes.
:Sample Code:
.. code-block:: python
import pytablewriter as ptw
from pytablewriter.style import Style
def main():
writer = ptw.MarkdownTableWriter(
table_name="set style by column_styles",
headers=[
"auto align",
"left align",
"center align",
"bold",
"italic",
"bold italic ts",
],
value_matrix=[
[11, 11, 11, 11, 11, 11],
[1234, 1234, 1234, 1234, 1234, 1234],
],
column_styles=[
Style(),
Style(align="left"),
Style(align="center"),
Style(font_weight="bold"),
Style(font_style="italic"),
Style(font_weight="bold", font_style="italic", thousand_separator=","),
], # specify styles for each column
)
writer.write_table()
if __name__ == "__main__":
main()
:Output:
.. code-block::
# set style by styles
|auto align|left align|center align| bold |italic|bold italic ts|
|---------:|----------|:----------:|-------:|-----:|-------------:|
| 11|11 | 11 | **11**| _11_| _**11**_|
| 1234|1234 | 1234 |**1234**|_1234_| _**1,234**_|
`Rendering result `__
You can also set ``Style`` to a specific column with an index or header by using ``set_style`` method:
:Sample Code:
.. code-block:: python
from pytablewriter import MarkdownTableWriter
from pytablewriter.style import Style
def main():
writer = MarkdownTableWriter()
writer.headers = ["A", "B", "C",]
writer.value_matrix = [[11, 11, 11], [1234, 1234, 1234]]
writer.table_name = "set style by column index"
writer.set_style(1, Style(align="center", font_weight="bold"))
writer.set_style(2, Style(thousand_separator=" "))
writer.write_table()
writer.write_null_line()
writer.table_name = "set style by header"
writer.set_style("B", Style(font_style="italic"))
writer.write_table()
if __name__ == "__main__":
main()
:Output:
.. code-block::
# set style by column index
| A | B | C |
|---:|:------:|----:|
| 11| **11** | 11|
|1234|**1234**|1 234|
# set style by header
| A | B | C |
|---:|-----:|----:|
| 11| _11_| 11|
|1234|_1234_|1 234|
Style filter
~~~~~~~~~~~~~~
You can apply styles to specific cells by using style filters.
Style filters will be written as Python functions.
Examples of a style filter function and how you apply it are as follows:
:Sample Code:
.. code-block:: python
from typing import Any, Optional
from pytablewriter import MarkdownTableWriter
from pytablewriter.style import Cell, Style
def style_filter(cell: Cell, **kwargs: Any) -> Optional[Style]:
if cell.is_header_row():
return None
if cell.col == 0:
return Style(font_weight="bold")
value = int(cell.value)
if value > 80:
return Style(fg_color="red", font_weight="bold", decoration_line="underline")
elif value > 50:
return Style(fg_color="yellow", font_weight="bold")
elif value > 20:
return Style(fg_color="green")
return Style(fg_color="lightblue")
writer = MarkdownTableWriter(
table_name="style filter example",
headers=["Key", "Value 1", "Value 2"],
value_matrix=[
["A", 95, 40],
["B", 55, 5],
["C", 30, 85],
["D", 0, 69],
],
flavor="github",
enable_ansi_escape=False,
)
writer.add_style_filter(style_filter)
writer.write_table()
Rendered results can be found at `here `__
Theme
~~~~~~~
`Theme `
consists of a set of style filters.
The following command will install external predefined themes:
::
pip install pytablewriter[theme]
Themes can be set via the constructor of the writer classes or the ``set_theme`` method.
The following is an example of setting the ``altrow`` theme via the constructor.
``altrow`` theme will be colored rows alternatively:
:Sample Code:

Make tables for specific applications
---------------------------------------
Render a table on Jupyter Notebook
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
All table writer class instances in ``pytablewriter`` can render in Jupyter Notebook.
To render writers at notebook cells, you will require the dependency packages to be installed either by:
- ``pip install pytablewriter[html]`` or
- ``pip install pytablewriter[all]``
Jupyter Notebook code examples can be found `here `__:

Multibyte character support
-----------------------------
Write a table using multibyte character
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
You can use multibyte characters as table data.
Multibyte characters are also properly padded and aligned.
:Sample Code:
.. code-block:: python
import pytablewriter as ptw
def main():
writer = ptw.RstSimpleTableWriter(
table_name="生成に関するパターン",
headers=["パターン名", "概要", "GoF", "Code Complete[1]"],
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()
if __name__ == "__main__":
main()
:Output:
.. figure:: https://cdn.jsdelivr.net/gh/thombashi/pytablewriter@master/docs/pages/examples/multibyte/ss/multi_byte_char.png

Multiprocessing
-----------------
You can increase the number of workers to process table data via ``max_workers`` attribute of a writer.
The more ``max_workers`` the less processing time when tabular data is large and the execution environment has available cores.
If you increase ``max_workers`` larger than one, recommend using main guarded as follows to avoid problems caused by multi-processing:
.. code-block:: python
from multiprocessing import cpu_count
import pytablewriter as ptw
def main():
writer = ptw.MarkdownTableWriter()
writer.max_workers = cpu_count()
...
if __name__ == "__main__":
main()
