Tables
======

Rich's :class:`~rich.table.Table` class offers a variety of ways to render tabular data to the terminal.

To render a table, construct a :class:`~rich.table.Table` object, add columns with :meth:`~rich.table.Table.add_column`, and rows with :meth:`~rich.table.Table.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:

Rich is quite smart about rendering the table. It will adjust the column widths to fit the contents and will wrap text if it doesn't fit. You can also add anything that Rich knows how to render as a title or row cell (even another table)!

You can set the border style by importing one of the preset :class:`~rich.box.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 :ref:`appendix_box` for other box styles.

The :class:`~rich.table.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.


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 :class:`~rich.table.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 an :class:`~rich.table.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"
    )

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.

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 :meth:`~rich.table.Table.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)
