Tables

Rich’s Table class offers a variety of ways to render tabular data to the terminal.

To render a table, construct a Table object, add columns with add_column(), and rows with add_row() – then print it to the console.

Here’s an example:

from rich.console import Console
from rich.table import Table

table = Table(title="Star Wars Movies")

table.add_column("Released", justify="right", style="cyan", no_wrap=True)
table.add_column("Title", style="magenta")
table.add_column("Box Office", justify="right", style="green")

table.add_row("Dec 20, 2019", "Star Wars: The Rise of Skywalker", "$952,110,690")
table.add_row("May 25, 2018", "Solo: A Star Wars Story", "$393,151,347")
table.add_row("Dec 15, 2017", "Star Wars Ep. V111: The Last Jedi", "$1,332,539,889")
table.add_row("Dec 16, 2016", "Rogue One: A Star Wars Story", "$1,332,439,889")

console = Console()
console.print(table)

This produces the following output:

                           Star Wars Movies                           
┏━━━━━━━━━━━━━━┳━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┳━━━━━━━━━━━━━━━━┓

Rich will calculate the optimal column sizes to fit your content, and will wrap text to fit if the terminal is not wide enough to fit the contents.

Note

You are not limited to adding text in the add_row method. You can add anything that Rich knows how to render (including another table).

Table Options

There are a number of keyword arguments on the Table constructor you can use to define how a table should look.

  • title Sets the title of the table (text show above the table).

  • caption Sets the table caption (text show below the table).

  • width Sets the desired width of the table (disables automatic width calculation).

  • min_width Sets a minimum width for the table.

  • box Sets one of the Box styles for the table grid, or None for no grid.

  • safe_box Set to True to force the table to generate ASCII characters rather than unicode.

  • padding A integer, or tuple of 1, 2, or 4 values to set the padding on cells.

  • collapse_padding If True the padding of neighboring cells will be merged.

  • pad_edge Set to False to remove padding around the edge of the table.

  • expand Set to True to expand the table to the full available size.

  • show_header Set to True to show a header, False to disable it.

  • show_footer Set to True to show a footer, False to disable it.

  • show_edge Set to False to disable the edge line around the table.

  • show_lines Set to True to show lines between rows as well as header / footer.

  • leading Additional space between rows.

  • style A Style to apply to the entire table, e.g. “on blue”

  • row_styles Set to a list of styles to style alternating rows. e.g. ["dim", ""] to create zebra stripes

  • header_style Set the default style for the header.

  • footer_style Set the default style for the footer.

  • border_style Set a style for border characters.

  • title_style Set a style for the title.

  • caption_style Set a style for the caption.

  • title_justify Set the title justify method (“left”, “right”, “center”, or “full”)

  • caption_justify Set the caption justify method (“left”, “right”, “center”, or “full”)

  • highlight Set to True to enable automatic highlighting of cell contents.

Border Styles

You can set the border style by importing one of the preset Box objects and setting the box argument in the table constructor. Here’s an example that modifies the look of the Star Wars table:

from rich import box
table = Table(title="Star Wars Movies", box=box.MINIMAL_DOUBLE_HEAD)

See Box for other box styles.

You can also set box=None to remove borders entirely.

The Table class offers a number of configuration options to set the look and feel of the table, including how borders are rendered and the style and alignment of the columns.

Lines

By default, Tables will show a line under the header only. If you want to show lines between all rows add show_lines=True to the constructor.

You can also force a line on the next row by setting end_section=True on the call to add_row(), or by calling the add_section() to add a line between the current and subsequent rows.

Empty Tables

Printing a table with no columns results in a blank line. If you are building a table dynamically and the data source has no columns, you might want to print something different. Here’s how you might do that:

if table.columns:
    print(table)
else:
    print("[i]No data...[/i]")

Adding Columns

You may also add columns by specifying them in the positional arguments of the Table constructor. For example, we could construct a table with three columns like this:

table = Table("Released", "Title", "Box Office", title="Star Wars Movies")

This allows you to specify the text of the column only. If you want to set other attributes, such as width and style, you can add a Column class. Here’s an example:

from rich.table import Column
table = Table(
    "Released",
    "Title",
    Column(header="Box Office", justify="right"),
    title="Star Wars Movies"
)

Column Options

There are a number of options you can set on a column to modify how it will look.

  • header_style Sets the style of the header, e.g. “bold magenta”.

  • footer_style Sets the style of the footer.

  • style Sets a style that applies to the column. You could use this to highlight a column by setting the background with “on green” for example.

  • justify Sets the text justify to one of “left”, “center”, “right”, or “full”.

  • vertical Sets the vertical alignment of the cells in a column, to one of “top”, “middle”, or “bottom”.

  • width Explicitly set the width of a row to a given number of characters (disables automatic calculation).

  • min_width When set to an integer will prevent the column from shrinking below this amount.

  • max_width When set to an integer will prevent the column from growing beyond this amount.

  • ratio Defines a ratio to set the column width. For instance, if there are 3 columns with a total of 6 ratio, and ratio=2 then the column will be a third of the available size.

  • no_wrap Set to True to prevent this column from wrapping.

Vertical Alignment

You can define the vertical alignment of a column by setting the vertical parameter of the column. You can also do this per-cell by wrapping your text or renderable with a Align class:

table.add_row(Align("Title", vertical="middle"))

Grids

The Table class can also make a great layout tool. If you disable headers and borders you can use it to position content within the terminal. The alternative constructor grid() can create such a table for you.

For instance, the following code displays two pieces of text aligned to both the left and right edges of the terminal on a single line:

from rich import print
from rich.table import Table

grid = Table.grid(expand=True)
grid.add_column()
grid.add_column(justify="right")
grid.add_row("Raising shields", "[bold magenta]COMPLETED [green]:heavy_check_mark:")

print(grid)
