Как установить tabulate python
Pretty-print tabular data in Python, a library and a command-line utility.
The main use cases of the library are:
To install the Python library and the command line utility, run:
The command line utility will be installed as tabulate to bin on Linux (e.g. /usr/bin ); or as tabulate.exe to Scripts in your Python installation on Windows (e.g. C:\Python27\Scripts\tabulate.exe ).
You may consider installing the library only for the current user:
In this case the command line utility will be installed to
/.local/bin/tabulate on Linux and to %APPDATA%\Python\Scripts\tabulate.exe on Windows.
To install just the library on Unix-like operating systems:
The following tabular data types are supported:
Examples in this file use Python2. Tabulate supports Python3 too.
The second optional argument named headers defines a list of column headers to be used:
There is more than one way to format a table in plain text. The third optional argument named tablefmt defines how the table is formatted.
Supported table formats are:
plain tables do not use any pseudo-graphics to draw lines:
simple is the default format (the default may change in future versions). It corresponds to simple_tables in Pandoc Markdown extensions:
github follows the conventions of GitHub flavored Markdown. It corresponds to the pipe format without alignment colons:
grid is like tables formatted by Emacs’ table.el package. It corresponds to grid_tables in Pandoc Markdown extensions:
fancy_grid draws a grid using box-drawing characters:
presto is like tables formatted by Presto cli:
pretty attempts to be close to the format emitted by the PrettyTables library:
psql is like tables formatted by Postgres’ psql cli:
pipe follows the conventions of PHP Markdown Extra extension. It corresponds to pipe_tables in Pandoc. This format uses colons to indicate column alignment:
orgtbl follows the conventions of Emacs org-mode, and is editable also in the minor orgtbl-mode. Hence its name:
jira follows the conventions of Atlassian Jira markup language:
rst formats data like a simple table of the reStructuredText format:
mediawiki format produces a table markup used in Wikipedia and on other MediaWiki-based sites:
moinmoin format produces a table markup used in MoinMoin wikis:
youtrack format produces a table markup used in Youtrack tickets:
textile format produces a table markup used in Textile format:

latex format creates a tabular environment for LaTeX markup, replacing special characters like _ or \ to their LaTeX correspondents:
latex_raw behaves like latex but does not escape LaTeX commands and special characters.
latex_booktabs creates a tabular environment for LaTeX markup using spacing and style from the booktabs package.
latex_longtable creates a table that can stretch along multiple pages, using the longtable package.
tabulate is smart about column alignment. It detects columns which contain only numbers, and aligns them by a decimal point (or flushes them to the right if they appear to be integers). Text columns are flushed to the left.
Aligning by a decimal point works best when you need to compare numbers at a glance:
Compare this with a more common right alignment:
Custom column alignment
tabulate allows to define custom number formatting applied to all columns of decimal numbers. Use floatfmt named argument:
floatfmt argument can be a list or a tuple of format strings, one per column, in which case every column may have different number formatting:
By default, tabulate removes leading and trailing whitespace from text columns. To disable whitespace removal, set the global module-level flag PRESERVE_WHITESPACE :
Wide (fullwidth CJK) symbols
To properly align tables which contain wide characters (typically fullwidth glyphs from Chinese, Japanese or Korean languages), the user should install wcwidth library. To install it together with tabulate :
Most table formats support multiline cell text (text containing newline characters). The newline characters are honored as line break characters.
Multiline cells are supported for data rows and for header rows.
Further automatic line breaks are not inserted. Of course, some output formats such as latex or html handle automatic formatting of the cell content on their own, but for those that don’t, the newline characters in the input cell text are the only means to break a line in cell text.
Note that some output formats (e.g. simple, or plain) do not represent row delimiters, so that the representation of multiline cells in such formats may be ambiguous to the reader.
The following examples of formatted output use the following table with a multiline cell, and headers with a multiline cell:
Multiline cells are not well supported for the other table formats.
While tabulate supports data passed in with multiines entries explicitly provided, it also provides some support to help manage this work internally.
The maxcolwidths argument is a list where each entry specifies the max width for it’s respective column. Any cell that will exceed this will automatically wrap the content. To assign the same max width for all columns, a singular int scaler can be used.
Use None for any columns where an explicit maximum does not need to be provided, and thus no automate multiline wrapping will take place.
This example demonstrates usagage of automatic multiline wrapping, though typically the lines being wrapped would probably be significantly longer than this.
Usage of the command line utility
Such features as decimal point alignment and trying to parse everything as a number imply that tabulate :
It may not be suitable for serializing really big tables (but who’s going to do that, anyway?) or printing tables in performance sensitive applications. tabulate is about two orders of magnitude slower than simply joining lists of values with a tab, comma, or other separator.

Contributions should include tests and an explanation for the changes they propose. Documentation (examples, docstrings, README.md) should be updated accordingly.
This project uses pytest testing framework and tox to automate testing in different environments. Add tests to one of the files in the test/ folder.
To run tests on all supported Python versions, make sure all Python interpreters, pytest and tox are installed, then run tox in the root of the project source tree.

To enable NumPy and Pandas tests, run:
(this may take a long time the first time, because NumPy and Pandas will have to be installed in the new virtual environments)
