Bases: UIElement[Union[List[str], List[int]], Union[List[JSONType], IntoDataFrame]]

A table component with selectable rows.

Get the selected rows with table.value. The table data can be supplied as:

a list of dicts, with one dict for each row, keyed by column names;
a list of values, representing a table with a single column;
a Pandas dataframe; or
a Polars dataframe; or
an Ibis dataframe; or
a PyArrow table.

Examples:

Create a table from a list of dicts, one for each row:

table = mo.ui.table(
    data=[
        {"first_name": "Michael", "last_name": "Scott"},
        {"first_name": "Dwight", "last_name": "Schrute"},
    ],
    label="Users",
)

Create a table from a single column of data:

table = mo.ui.table(
    data=[
        {"first_name": "Michael", "last_name": "Scott"},
        {"first_name": "Dwight", "last_name": "Schrute"},
    ],
    label="Users",
)

Create a table from a dataframe:

# df is a Pandas or Polars dataframe
table = mo.ui.table(
    data=df,
    # use pagination when your table has many rows
    pagination=True,
    label="Dataframe",
)

Create a table with format mapping:

# format_mapping is a dict keyed by column names,
# with values as formatting functions or strings
def format_name(name):
    return name.upper()


table = mo.ui.table(
    data=[
        {"first_name": "Michael", "last_name": "Scott", "age": 45},
        {"first_name": "Dwight", "last_name": "Schrute", "age": 40},
    ],
    format_mapping={
        "first_name": format_name,  # Use callable to format first names
        "age": "{:.1f}".format,  # Use string format for age
    },
    label="Format Mapping",
)

In each case, access the table data with table.value.

data `property` ¶

data: TableData

Get the original table data.

RETURNS	DESCRIPTION
`TableData`	The original data passed to the table constructor, in its original format (list, dict, dataframe, etc.). TYPE: `TableData`

text `property` ¶

text: str

A string of HTML representing this element.

value `property` `writable` ¶

value: T

The element's current value.

batch ¶

batch(**elements: UIElement[JSONType, object]) -> batch

Convert an HTML object with templated text into a UI element.

This method lets you create custom UI elements that are represented by arbitrary HTML.

Example

user_info = mo.md(
    '''
    - What's your name?: {name}
    - When were you born?: {birthday}
    '''
).batch(name=mo.ui.text(), birthday=mo.ui.date())

In this example, user_info is a UI Element whose output is markdown and whose value is a dict with keys 'name' and 'birthday' (and values equal to the values of their corresponding elements).

PARAMETER	DESCRIPTION
`elements`	the UI elements to interpolate into the HTML template. TYPE: `UIElement[JSONType, object]` DEFAULT: `{}`

callout ¶

callout(
    kind: Literal[
        "neutral", "danger", "warn", "success", "info"
    ] = "neutral"
) -> Html

Create a callout containing this HTML element.

A callout wraps your HTML element in a raised box, emphasizing its importance. You can style the callout for different situations with the kind argument.

Examples:

mo.md("Hooray, you did it!").callout(kind="success")

mo.md("It's dangerous to go alone!").callout(kind="warn")

center ¶

center() -> Html

Center an item.

Example

mo.md("# Hello, world").center()

RETURNS	DESCRIPTION
`Html`	An `Html` object.

form ¶

form(
    label: str = "",
    *,
    bordered: bool = True,
    loading: bool = False,
    submit_button_label: str = "Submit",
    submit_button_tooltip: Optional[str] = None,
    submit_button_disabled: bool = False,
    clear_on_submit: bool = False,
    show_clear_button: bool = False,
    clear_button_label: str = "Clear",
    clear_button_tooltip: Optional[str] = None,
    validate: Optional[
        Callable[[Optional[JSONType]], Optional[str]]
    ] = None,
    on_change: Optional[
        Callable[[Optional[T]], None]
    ] = None
) -> form[S, T]

Create a submittable form out of this UIElement.

Creates a form that gates submission of a UIElement's value until a submit button is clicked. The form's value is the value of the underlying element from the last submission.

Examples:

Convert any UIElement into a form:

prompt = mo.ui.text_area().form()

Combine with HTML.batch to create a form made out of multiple UIElements:

form = (
    mo.ui.md(
        '''
    **Enter your prompt.**

    {prompt}

    **Choose a random seed.**

    {seed}
    '''
    )
    .batch(
        prompt=mo.ui.text_area(),
        seed=mo.ui.number(),
    )
    .form()
