Developped by a M. Eng. student in AI & Data science, who usually find himself preparing reports of projects using LaTex. This implies summarizing results in tables, as we can find in a lot of scientific papers. In the context of Machine Learning projects, the results are most probably the output of a python code. So why copying them from python and have a painful time creating the table in LaTeX ?

The goal is to use python to translate these results directly into LaTeX format with a reasonable amount of customization while still working with Python!

• Work with multilevel column.
• Load data from dataframe, csv file or dictionary.
• Automatically highlight max/min by rows/cols.

You can clone the repository or simply installing it from PyPI using pip

pip install pytabtex

For the moment, the specific use case of this library is tables assembling results.

The columns parameter is a dictionary where each key is the name of the columns, the value is 0 if there are no subcolulmns, or a list of subcolumns names if there are subcolumns.

Example (simple columns) :

Desired output :

Python code :

columns = {"column 1" : 0, "column 2" : 0, "column 3" : 0, "column 4" : 0}

Example (multilevel columns) :

Desired output :

Python code :

columns = {"column 1" : ["Sub-column 1", "Sub-column 2"],\
           "column 2" : 0,
           "column 3" : 0}

The body of the table can be a dictionary, a pandas Dataframe or a csv file path.

Example

Dictionary

{
    "id 1" : [29, 31, 90],
    "id 2" : [97, 78, 67]
}

Dataframe

if the dataframe has a header, don't include it.

CSV file

if the dataframe has a header, don't include it.

csv_file = "path\to\csv"

• columns : columns defined in the format specified above.
• body : table rows in one of the different formats.
• title : title of the table if needed.
• highlight : {func : axis} defined as follows - max by rows : {max: 0}, max by cols : {min: 0}, min by rows : {min: 0}, min by cols : {min: 1}
• orientation : "P" for portrait and "L" for landscape
• position of the table : htbp by default, check latex for other positions.
• align cols : "c" center, "l" left, "r" right.

from pytabtex import Table

table = Table(columns = columns,\
              body = body,\
              title=None,\
              highlight=None,\
              caption=None,\
              orientation="P",\
              position="htbp",\
              align_cols="c"
            )
