terminaltables 1.2.0

Generate simple tables in terminals from a nested list of strings.

Easily draw tables in terminal/console applications from a list of lists of strings. Supports multi-line rows.

• Python 2.6, 2.7, PyPy, PyPy3, 3.3, and 3.4 supported on Linux and OS X.

• Python 2.7, 3.3, and 3.4 supported on Windows (both 32 and 64 bit versions of Python).

Tested on Windows XP and Windows 10 technical preview.

Quickstart

Install:

pip install terminaltables

Example Implementations

Source code for examples: example1.py, example2.py, and example3.py

Usage

The below usage information is for AsciiTable which uses simple ASCII characters for the table (e.g. - + |). Use SingleTable for box drawing characters instead. You may also use DoubleTable for double-lined box characters. All three tables have the same methods and properties and work on all platforms.

Simple Usage

from terminaltables import AsciiTable
table_data = [
    ['Heading1', 'Heading2'],
    ['row1 column1', 'row1 column2'],
    ['row2 column1', 'row2 column2'],
    ['row3 column1', 'row3 column2']
]
table = AsciiTable(table_data)
print table.table
+--------------+--------------+
| Heading1     | Heading2     |
+--------------+--------------+
| row1 column1 | row1 column2 |
| row2 column1 | row2 column2 |
| row3 column1 | row3 column2 |
+--------------+--------------+

table_data is a list of lists of strings. The outer list represents the whole table, while the inner lists represents rows. Each row-list holds strings which are the cells of that row.

The first row can be though of the heading, but it doesn’t have to be. You can turn off the heading separator (the only thing that makes the first row a “heading” row) by setting table.inner_heading_row_border = False.

table.inner_heading_row_border = False
print table.table
+--------------+--------------+
| Heading1     | Heading2     |
| row1 column1 | row1 column2 |
| row2 column1 | row2 column2 |
| row3 column1 | row3 column2 |
+--------------+--------------+

Sometimes the last row can be though of a total (summary) row, by default it isn’t. You can turn on the las row separator (the only thing that makes the last row a “total” row) by setting table.inner_footing_row_border = True.

table.inner_heading_row_border = True
table.inner_footing_row_border = True
print table.table
+--------------+--------------+
| Heading1     | Heading2     |
+--------------+--------------+
| row1 column1 | row1 column2 |
| row2 column1 | row2 column2 |
+--------------+--------------+
| row3 column1 | row3 column2 |
+--------------+--------------+

If you want to add colors or bold the heading row, you’ll have to do that yourself. Keep in mind that terminaltables relies on len() and other methods for calculating table borders. I suggest looking at colorclass for supporting colors in terminaltables since it handles color string lengths correctly.

Class Attributes

You can instantiate with AsciiTable(table_data) or AsciiTable(table_data, 'Table Title'). These are available after instantiating any table class.

Name	Description/Notes
table_data	List of list of strings. Same object passed to __init__().
title	Table title string. Default is None for no title.
inner_column_border	Default is True. Separates columns.
inner_footing_row_border	Default is False. This is what makes the last row a “footer row”.
inner_heading_row_border	Default is True. This is what makes the first row a “header row”.
inner_row_border	Default is False. This adds lines between rows.
justify_columns	Dictionary. Keys are column numbers (0 base), values are ‘left’, ‘right’, or ‘center’.
outer_border	Default is True. Toggles the top, bottom, left, and right table borders.
padding_left	Default is 1. Number of spaces to add to the left of the cell.
padding_right	Default is 1. Number of spaces to add to the right of the cell.

Class Methods

These are regular methods available in either class.

Name	Description/Notes
column_max_width	Takes one argument, column number (0 base). Returns The maximum size it will fit in the terminal without breaking the table. Takes other columns into account.

Class Properties

These are read-only properties after you instantiate either class. They are “real-time”. You do not have to re-instantiate if you change any of the class attributes, including table_data.

Name	Description/Notes
column_widths	Returns a list with the current column widths (one int per column) without padding.
ok	Returns True if the table fits within the terminal width, False if the table breaks.
padded_table_data	Returns the padding table data. With spaces and newlines. Does not include borders.
table	Returns a large string, the whole table. This may be printed to the terminal.
table_width	Returns the width of the table including padding and borders.
