python-tabulate
|
|
===============
|
|
|
|
Pretty-print tabular data in Python, a library and a command-line
|
|
utility.
|
|
|
|
The main use cases of the library are:
|
|
|
|
- printing small tables without hassle: just one function call,
|
|
formatting is guided by the data itself
|
|
- authoring tabular data for lightweight plain-text markup: multiple
|
|
output formats suitable for further editing or transformation
|
|
- readable presentation of mixed textual and numeric data: smart
|
|
column alignment, configurable number formatting, alignment by a
|
|
decimal point
|
|
|
|
Installation
|
|
------------
|
|
|
|
To install the Python library and the command line utility, run:
|
|
|
|
pip install tabulate
|
|
|
|
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:
|
|
|
|
pip install tabulate --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:
|
|
|
|
TABULATE_INSTALL=lib-only pip install tabulate
|
|
|
|
On Windows:
|
|
|
|
set TABULATE_INSTALL=lib-only
|
|
pip install tabulate
|
|
|
|
The module provides just one function, `tabulate`, which takes a list of
|
|
lists or another tabular data type as the first argument, and outputs a
|
|
nicely formatted plain-text table:
|
|
|
|
>>> from tabulate import tabulate
|
|
|
|
>>> table = [["Sun",696000,1989100000],["Earth",6371,5973.6],
|
|
... ["Moon",1737,73.5],["Mars",3390,641.85]]
|
|
>>> print(tabulate(table))
|
|
----- ------ -------------
|
|
Sun 696000 1.9891e+09
|
|
Earth 6371 5973.6
|
|
Moon 1737 73.5
|
|
Mars 3390 641.85
|
|
----- ------ -------------
|
|
|
|
The following tabular data types are supported:
|
|
|
|
- list of lists or another iterable of iterables
|
|
- list or another iterable of dicts (keys as columns)
|
|
- dict of iterables (keys as columns)
|
|
- two-dimensional NumPy array
|
|
- NumPy record arrays (names as columns)
|
|
- pandas.DataFrame
|
|
|
|
Examples in this file use Python2. Tabulate supports Python3 too.
|
|
|
|
### Headers
|
|
|
|
The second optional argument named `headers` defines a list of column
|
|
headers to be used:
|
|
|
|
>>> print(tabulate(table, headers=["Planet","R (km)", "mass (x 10^29 kg)"]))
|
|
Planet R (km) mass (x 10^29 kg)
|
|
-------- -------- -------------------
|
|
Sun 696000 1.9891e+09
|
|
Earth 6371 5973.6
|
|
Moon 1737 73.5
|
|
Mars 3390 641.85
|
|
|
|
If `headers="firstrow"`, then the first row of data is used:
|
|
|
|
>>> print(tabulate([["Name","Age"],["Alice",24],["Bob",19]],
|
|
... headers="firstrow"))
|
|
Name Age
|
|
------ -----
|
|
Alice 24
|
|
Bob 19
|
|
|
|
If `headers="keys"`, then the keys of a dictionary/dataframe, or column
|
|
indices are used. It also works for NumPy record arrays and lists of
|
|
dictionaries or named tuples:
|
|
|
|
>>> print(tabulate({"Name": ["Alice", "Bob"],
|
|
... "Age": [24, 19]}, headers="keys"))
|
|
Age Name
|
|
----- ------
|
|
24 Alice
|
|
19 Bob
|
|
|
|
### Row Indices
|
|
|
|
By default, only pandas.DataFrame tables have an additional column
|
|
called row index. To add a similar column to any other type of table,
|
|
pass `showindex="always"` or `showindex=True` argument to `tabulate()`.
|
|
To suppress row indices for all types of data, pass `showindex="never"`
|
|
or `showindex=False`. To add a custom row index column, pass
|
|
`showindex=rowIDs`, where `rowIDs` is some iterable:
|
|
|
|
>>> print(tabulate([["F",24],["M",19]], showindex="always"))
|
|
- - --
|
|
0 F 24
|
|
1 M 19
|
|
- - --
|
|
|
|
### Table format
|
|
|
|
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"
|
|
- "simple"
|
|
- "github"
|
|
- "grid"
|
|
- "fancy\_grid"
|
|
- "pipe"
|
|
- "orgtbl"
|
|
- "jira"
|
|
- "presto"
|
|
- "pretty"
|
|
- "psql"
|
|
- "rst"
|
|
- "mediawiki"
|
|
- "moinmoin"
|
|
- "youtrack"
|
|
- "html"
|
|
- "unsafehtml"
|
|
- "latex"
|
|
- "latex\_raw"
|
|
- "latex\_booktabs"
|
|
- "latex\_longtable"
|
|
- "textile"
|
|
- "tsv"
|
|
|
|
`plain` tables do not use any pseudo-graphics to draw lines:
|
|
|
|
>>> table = [["spam",42],["eggs",451],["bacon",0]]
|
|
>>> headers = ["item", "qty"]
|
|
>>> print(tabulate(table, headers, tablefmt="plain"))
|
|
item qty
|
|
spam 42
|
|
eggs 451
|
|
bacon 0
|
|
|
|
`simple` is the default format (the default may change in future
|
|
versions). It corresponds to `simple_tables` in [Pandoc Markdown
|
|
extensions](http://johnmacfarlane.net/pandoc/README.html#tables):
|
|
|
|
>>> print(tabulate(table, headers, tablefmt="simple"))
|
|
item qty
|
|
------ -----
|
|
spam 42
|
|
eggs 451
|
|
bacon 0
|
|
|
|
`github` follows the conventions of GitHub flavored Markdown. It
|
|
corresponds to the `pipe` format without alignment colons:
|
|
|
|
>>> print(tabulate(table, headers, tablefmt="github"))
|
|
| item | qty |
|
|
|--------|-------|
|
|
| spam | 42 |
|
|
| eggs | 451 |
|
|
| bacon | 0 |
|
|
|
|
`grid` is like tables formatted by Emacs'
|
|
[table.el](http://table.sourceforge.net/) package. It corresponds to
|
|
`grid_tables` in Pandoc Markdown extensions:
|
|
|
|
>>> print(tabulate(table, headers, tablefmt="grid"))
|
|
+--------+-------+
|
|
| item | qty |
|
|
+========+=======+
|
|
| spam | 42 |
|
|
+--------+-------+
|
|
| eggs | 451 |
|
|
+--------+-------+
|
|
| bacon | 0 |
|
|
+--------+-------+
|
|
|
|
`fancy_grid` draws a grid using box-drawing characters:
|
|
|
|
>>> print(tabulate(table, headers, tablefmt="fancy_grid"))
|
|
╒════════╤═══════╕
|
|
│ item │ qty │
|
|
╞════════╪═══════╡
|
|
│ spam │ 42 │
|
|
├────────┼───────┤
|
|
│ eggs │ 451 │
|
|
├────────┼───────┤
|
|
│ bacon │ 0 │
|
|
╘════════╧═══════╛
|
|
|
|
`presto` is like tables formatted by Presto cli:
|
|
|
|
>>> print(tabulate(table, headers, tablefmt="presto"))
|
|
item | qty
|
|
--------+-------
|
|
spam | 42
|
|
eggs | 451
|
|
bacon | 0
|
|
|
|
`pretty` attempts to be close to the format emitted by the PrettyTables
|
|
library:
|
|
|
|
>>> print(tabulate(table, headers, tablefmt="pretty"))
|
|
+-------+-----+
|
|
| item | qty |
|
|
+-------+-----+
|
|
| spam | 42 |
|
|
| eggs | 451 |
|
|
| bacon | 0 |
|
|
+-------+-----+
|
|
|
|
`psql` is like tables formatted by Postgres' psql cli:
|
|
|
|
>>> print(tabulate(table, headers, tablefmt="psql"))
|
|
+--------+-------+
|
|
| item | qty |
|
|
|--------+-------|
|
|
| spam | 42 |
|
|
| eggs | 451 |
|
|
| bacon | 0 |
|
|
+--------+-------+
|
|
|
|
`pipe` follows the conventions of [PHP Markdown
|
|
Extra](http://michelf.ca/projects/php-markdown/extra/#table) extension.
|
|
It corresponds to `pipe_tables` in Pandoc. This format uses colons to
|
|
indicate column alignment:
|
|
|
|
>>> print(tabulate(table, headers, tablefmt="pipe"))
|
|
| item | qty |
|
|
|:-------|------:|
|
|
| spam | 42 |
|
|
| eggs | 451 |
|
|
| bacon | 0 |
|
|
|
|
`orgtbl` follows the conventions of Emacs
|
|
[org-mode](http://orgmode.org/manual/Tables.html), and is editable also
|
|
in the minor orgtbl-mode. Hence its name:
|
|
|
|
>>> print(tabulate(table, headers, tablefmt="orgtbl"))
|
|
| item | qty |
|
|
|--------+-------|
|
|
| spam | 42 |
|
|
| eggs | 451 |
|
|
| bacon | 0 |
|
|
|
|
`jira` follows the conventions of Atlassian Jira markup language:
|
|
|
|
>>> print(tabulate(table, headers, tablefmt="jira"))
|
|
|| item || qty ||
|
|
| spam | 42 |
|
|
| eggs | 451 |
|
|
| bacon | 0 |
|
|
|
|
`rst` formats data like a simple table of the
|
|
[reStructuredText](http://docutils.sourceforge.net/docs/user/rst/quickref.html#tables)
|
|
format:
|
|
|
|
>>> print(tabulate(table, headers, tablefmt="rst"))
|
|
====== =====
|
|
item qty
|
|
====== =====
|
|
spam 42
|
|
eggs 451
|
|
bacon 0
|
|
====== =====
|
|
|
|
`mediawiki` format produces a table markup used in
|
|
[Wikipedia](http://www.mediawiki.org/wiki/Help:Tables) and on other
|
|
MediaWiki-based sites:
|
|
|
|
>>> print(tabulate(table, headers, tablefmt="mediawiki"))
|
|
{| class="wikitable" style="text-align: left;"
|
|
|+ <!-- caption -->
|
|
|-
|
|
! item !! align="right"| qty
|
|
|-
|
|
| spam || align="right"| 42
|
|
|-
|
|
| eggs || align="right"| 451
|
|
|-
|
|
| bacon || align="right"| 0
|
|
|}
|
|
|
|
`moinmoin` format produces a table markup used in
|
|
[MoinMoin](https://moinmo.in/) wikis:
|
|
|
|
>>> print(tabulate(table, headers, tablefmt="moinmoin"))
|
|
|| ''' item ''' || ''' quantity ''' ||
|
|
|| spam || 41.999 ||
|
|
|| eggs || 451 ||
|
|
|| bacon || ||
|
|
|
|
`youtrack` format produces a table markup used in Youtrack tickets:
|
|
|
|
>>> print(tabulate(table, headers, tablefmt="youtrack"))
|
|
|| item || quantity ||
|
|
| spam | 41.999 |
|
|
| eggs | 451 |
|
|
| bacon | |
|
|
|
|
`textile` format produces a table markup used in
|
|
[Textile](http://redcloth.org/hobix.com/textile/) format:
|
|
|
|
>>> print(tabulate(table, headers, tablefmt="textile"))
|
|
|_. item |_. qty |
|
|
|<. spam |>. 42 |
|
|
|<. eggs |>. 451 |
|
|
|<. bacon |>. 0 |
|
|
|
|
`html` produces standard HTML markup as an html.escape'd str
|
|
with a ._repr_html_ method so that Jupyter Lab and Notebook display the HTML
|
|
and a .str property so that the raw HTML remains accessible.
|
|
`unsafehtml` table format can be used if an unescaped HTML is required:
|
|
|
|
>>> print(tabulate(table, headers, tablefmt="html"))
|
|
<table>
|
|
<tbody>
|
|
<tr><th>item </th><th style="text-align: right;"> qty</th></tr>
|
|
<tr><td>spam </td><td style="text-align: right;"> 42</td></tr>
|
|
<tr><td>eggs </td><td style="text-align: right;"> 451</td></tr>
|
|
<tr><td>bacon </td><td style="text-align: right;"> 0</td></tr>
|
|
</tbody>
|
|
</table>
|
|
|
|
`latex` format creates a `tabular` environment for LaTeX markup,
|
|
replacing special characters like `_` or `\` to their LaTeX
|
|
correspondents:
|
|
|
|
>>> print(tabulate(table, headers, tablefmt="latex"))
|
|
\begin{tabular}{lr}
|
|
\hline
|
|
item & qty \\
|
|
\hline
|
|
spam & 42 \\
|
|
eggs & 451 \\
|
|
bacon & 0 \\
|
|
\hline
|
|
\end{tabular}
|
|
|
|
`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.
|
|
|
|
### Column alignment
|
|
|
|
`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.
|
|
|
|
You can override the default alignment with `numalign` and `stralign`
|
|
named arguments. Possible column alignments are: `right`, `center`,
|
|
`left`, `decimal` (only for numbers), and `None` (to disable alignment).
|
|
|
|
Aligning by a decimal point works best when you need to compare numbers
|
|
at a glance:
|
|
|
|
>>> print(tabulate([[1.2345],[123.45],[12.345],[12345],[1234.5]]))
|
|
----------
|
|
1.2345
|
|
123.45
|
|
12.345
|
|
12345
|
|
1234.5
|
|
----------
|
|
|
|
Compare this with a more common right alignment:
|
|
|
|
>>> print(tabulate([[1.2345],[123.45],[12.345],[12345],[1234.5]], numalign="right"))
|
|
------
|
|
1.2345
|
|
123.45
|
|
12.345
|
|
12345
|
|
1234.5
|
|
------
|
|
|
|
For `tabulate`, anything which can be parsed as a number is a number.
|
|
Even numbers represented as strings are aligned properly. This feature
|
|
comes in handy when reading a mixed table of text and numbers from a
|
|
file:
|
|
|
|
>>> import csv ; from StringIO import StringIO
|
|
>>> table = list(csv.reader(StringIO("spam, 42\neggs, 451\n")))
|
|
>>> table
|
|
[['spam', ' 42'], ['eggs', ' 451']]
|
|
>>> print(tabulate(table))
|
|
---- ----
|
|
spam 42
|
|
eggs 451
|
|
---- ----
|
|
|
|
|
|
To disable this feature use `disable_numparse=True`.
|
|
|
|
>>> print(tabulate.tabulate([["Ver1", "18.0"], ["Ver2","19.2"]], tablefmt="simple", disable_numparse=True))
|
|
---- ----
|
|
Ver1 18.0
|
|
Ver2 19.2
|
|
---- ----
|
|
|
|
|
|
### Custom column alignment
|
|
|
|
`tabulate` allows a custom column alignment to override the above. The
|
|
`colalign` argument can be a list or a tuple of `stralign` named
|
|
arguments. Possible column alignments are: `right`, `center`, `left`,
|
|
`decimal` (only for numbers), and `None` (to disable alignment).
|
|
Omitting an alignment uses the default. For example:
|
|
|
|
>>> print(tabulate([["one", "two"], ["three", "four"]], colalign=("right",))
|
|
----- ----
|
|
one two
|
|
three four
|
|
----- ----
|
|
|
|
### Number formatting
|
|
|
|
`tabulate` allows to define custom number formatting applied to all
|
|
columns of decimal numbers. Use `floatfmt` named argument:
|
|
|
|
>>> print(tabulate([["pi",3.141593],["e",2.718282]], floatfmt=".4f"))
|
|
-- ------
|
|
pi 3.1416
|
|
e 2.7183
|
|
-- ------
|
|
|
|
`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:
|
|
|
|
>>> print(tabulate([[0.12345, 0.12345, 0.12345]], floatfmt=(".1f", ".3f")))
|
|
--- ----- -------
|
|
0.1 0.123 0.12345
|
|
--- ----- -------
|
|
|
|
### Text formatting
|
|
|
|
By default, `tabulate` removes leading and trailing whitespace from text
|
|
columns. To disable whitespace removal, set the global module-level flag
|
|
`PRESERVE_WHITESPACE`:
|
|
|
|
import tabulate
|
|
tabulate.PRESERVE_WHITESPACE = True
|
|
|
|
### 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`:
|
|
|
|
pip install tabulate[widechars]
|
|
|
|
Wide character support is enabled automatically if `wcwidth` library is
|
|
already installed. To disable wide characters support without
|
|
uninstalling `wcwidth`, set the global module-level flag
|
|
`WIDE_CHARS_MODE`:
|
|
|
|
import tabulate
|
|
tabulate.WIDE_CHARS_MODE = False
|
|
|
|
### Multiline cells
|
|
|
|
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:
|
|
|
|
>>> table = [["eggs",451],["more\nspam",42]]
|
|
>>> headers = ["item\nname", "qty"]
|
|
|
|
`plain` tables:
|
|
|
|
>>> print(tabulate(table, headers, tablefmt="plain"))
|
|
item qty
|
|
name
|
|
eggs 451

Usage of the command line utility
|
|
---------------------------------
|
|
|
|
Usage: tabulate [options] [FILE ...]
|
|
|
|
FILE a filename of the file with tabular data;
|
|
if "-" or missing, read data from stdin.
|
|
|
|
Options:
|
|
|
|
-h, --help show this message
|
|
-1, --header use the first row of data as a table header
|
|
-o FILE, --output FILE print table to FILE (default: stdout)
|
|
-s REGEXP, --sep REGEXP use a custom column separator (default: whitespace)
|
|
-F FPFMT, --float FPFMT floating point number format (default: g)
|
|
-f FMT, --format FMT set output table format; supported formats:
|
|
plain, simple, github, grid, fancy_grid, pipe,
|
|
orgtbl, rst, mediawiki, html, latex, latex_raw,
|
|
latex_booktabs, latex_longtable, tsv
|
|
(default: simple)
|
|
|
|
Performance considerations
|
|
--------------------------
|
|
|
|
Such features as decimal point alignment and trying to parse everything
|
|
as a number imply that `tabulate`:
|
|
|
|
- has to "guess" how to print a particular tabular data type
|
|
- needs to keep the entire table in-memory
|
|
- has to "transpose" the table twice
|
|
- does much more work than it may appear
|
|
|
|
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.
|
|
|
|
At the same time, `tabulate` is comparable to other table
|
|
pretty-printers. Given a 10x10 table (a list of lists) of mixed text and
|
|
numeric data, `tabulate` appears to be slower than `asciitable`, and
|
|
faster than `PrettyTable` and `texttable` The following mini-benchmark
|
|
was run in Python 3.8.3 in Windows 10 x64:
|
|
|
|
================================= ========== ===========
|
|

|
|
PrettyTable (0.7.2) 879.1 70.6
|
|
texttable (1.6.2) 1352.2 108.6

How to contribute
|
|
-----------------
|
|
|
|
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](https://docs.pytest.org/) testing
|
|
framework and [tox](https://tox.readthedocs.io/) 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.
|
|
|
|
On Linux `tox` expects to find executables like `python2.6`,
|
|
`python2.7`, `python3.4` etc. On Windows it looks for
|
|
`C:\Python26\python.exe`, `C:\Python27\python.exe` and
|
|
`C:\Python34\python.exe` respectively.
|
|
|
|
To test only some Python environments, use `-e` option. For example, to
|
|
test only against Python 2.7 and Python 3.8, run:
|
|
|
|
tox -e py27,py38
|
|
|
|
in the root of the project source tree.
|
|
|
|
To enable NumPy and Pandas tests, run:
|
|
|
|
tox -e py27-extra,py38-extra
|
|
|
|
(this may take a long time the first time, because NumPy and Pandas will
|
|
have to be installed in the new virtual environments)
|
|
|
|
To fix code formatting:
|
|
|
|
tox -e lint
|
|
|
|
See `tox.ini` file to learn how to use to test
|
|
individual Python versions.
