Write a Markdown table from pandas.DataFrame
instance
``from_dataframe`` method of writer classes will set up tabular data from ``pandas.DataFrame``:
:Sample Code:
.. code-block:: python
from textwrap import dedent
import pandas as pd
import io
from pytablewriter import MarkdownTableWriter
def main():
csv_data = io.StringIO(dedent("""\
"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 = MarkdownTableWriter()
writer.from_dataframe(df)
writer.write_table()
if __name__ == "__main__":
main()
:Output:
.. code-block::
| 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|
Adding a column of the DataFrame index if you specify ``add_index_column=True``:
:Sample Code:
.. code-block:: python
import pandas as pd
from pytablewriter import MarkdownTableWriter
def main():
writer = MarkdownTableWriter()
writer.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()
if __name__ == "__main__":
main()
:Output:
.. code-block::
# add_index_column

Write a markdown table from a space-separated values
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
:Sample Code:
.. code-block:: python

def main():
writer = pytablewriter.MarkdownTableWriter()
writer.table_name = "ps"
writer.from_csv(
dedent("""\

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
def main():
writer = pytablewriter.MarkdownTableWriter()
writer.headers = ["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"],
]
print(writer.dumps())
if __name__ == "__main__":
main()
:Output:
.. code-block::

|-10|-9.90| |False| NaN|2017-01-01 00:00:00+0900|
Configure table styles
------------------------
Column styles
~~~~~~~~~~~~~~~
Writers can specify
`Style <https://pytablewriter.rtfd.io/en/latest/pages/reference/style.html>`__
for each column by ``column_styles`` attribute of writer classes.
:Sample Code:
.. code-block:: python
from pytablewriter import MarkdownTableWriter
from pytablewriter.style import Style
def main():
writer = MarkdownTableWriter()
writer.table_name = "set style by column_styles"
writer.headers = [
"auto align",
"left align",
"center align",
"bold",
"italic",
"bold italic ts",
]
writer.value_matrix = [
[11, 11, 11, 11, 11, 11],
[1234, 1234, 1234, 1234, 1234, 1234],
]
# specify styles for each column
writer.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=","),
]
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 <https://github.com/thombashi/pytablewriter/tree/master/docs/pages/examples/style/output.md>`__
You can also set ``Style`` to a specific column with 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
~~~~~~~~~~~~~~
``set_theme`` method can set predefined style filters.
The following command will install themes:
::
pip install pytablewriter[theme]
``altrow`` theme will colored rows alternatively:
:Sample Code:
.. code-block:: python
writer = TableWriterFactory.create_from_format_name("markdown")
writer.headers = ["INT", "STR"]
writer.value_matrix = [[1, "hoge"], [2, "foo"], [3, "bar"]]
writer.margin = 1
writer.set_theme("altrow")
writer.write_table()
:Output:

Make tables for specific applications
---------------------------------------
Render a table on Jupyter Notebook
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Table formatting for Jupyter Notebook
Multibyte character support
-----------------------------
Write a table using multibyte character
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
You can use multibyte characters as table data.
Multibyte characters also properly padded and aligned.
:Sample Code:
.. code-block:: python
import pytablewriter
def main():
writer = pytablewriter.RstSimpleTableWriter()
writer.table_name = "生成に関するパターン"
writer.headers = ["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()
if __name__ == "__main__":
main()
:Output:
.. figure:: https://cdn.jsdelivr.net/gh/thombashi/[email protected]/docs/pages/examples/multibyte/ss/multi_byte_char.png
:scale: 100%
:alt: https://github.com/thombashi/pytablewriter/blob/master/docs/pages/examples/multibyte/ss/multi_byte_char.png
Output of multi-byte character table
Multi processing
------------------
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 to use 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()
