gradio.Dataframe(···)
This component displays a table of value spreadsheet-like component. Can be used to display data as an output component, or as an input to collect data from the user.
As input component: Passes the uploaded spreadsheet data as a pandas.DataFrame
, numpy.array
, polars.DataFrame
, or native 2D Python list[list]
depending on type
Your function should accept one of these types:
def predict(
value: pd.DataFrame | np.ndarray | pl.DataFrame | list[list]
)
...
As output component: Expects data any of these formats: pandas.DataFrame
, pandas.Styler
, numpy.array
, polars.DataFrame
, list[list]
, list
, or a dict
with keys 'data' (and optionally 'headers'), or str
path to a csv, which is rendered as the spreadsheet.
Your function should return one of these types:
def predict(···) -> pd.DataFrame | Styler | np.ndarray | pl.DataFrame | list | list[list] | dict | str | None
...
return value
Parameter | Description |
---|---|
value pd.DataFrame | Styler | np.ndarray | pl.DataFrame | list | list[list] | dict | str | Callable | None default: None | Default value to display in the DataFrame. If a Styler is provided, it will be used to set the displayed value in the DataFrame (e.g. to set precision of numbers) if the |
headers list[str] | None default: None | List of str header names. If None, no headers are shown. |
row_count int | tuple[int, str] default: (1, 'dynamic') | Limit number of rows for input and decide whether user can create new rows. The first element of the tuple is an |
col_count int | tuple[int, str] | None default: None | Limit number of columns for input and decide whether user can create new columns. The first element of the tuple is an |
datatype str | list[str] default: "str" | Datatype of values in sheet. Can be provided per column as a list of strings, or for the entire sheet as a single string. Valid datatypes are "str", "number", "bool", "date", and "markdown". |
type Literal[('pandas', 'numpy', 'array', 'polars')] default: "pandas" | Type of value to be returned by component. "pandas" for pandas dataframe, "numpy" for numpy array, "polars" for polars dataframe, or "array" for a Python list of lists. |
latex_delimiters list[dict[str, str | bool]] | None default: None | A list of dicts of the form |
label str | None default: None | The label for this component. Appears above the component and is also used as the header if there are a table of examples for this component. If None and used in a |
show_label bool | None default: None | if True, will display label. |
every float | None default: None | If |
height int default: 500 | The maximum height of the dataframe, specified in pixels if a number is passed, or in CSS units if a string is passed. If more rows are created than can fit in the height, a scrollbar will appear. |
scale int | None default: None | relative size compared to adjacent Components. For example if Components A and B are in a Row, and A has scale=2, and B has scale=1, A will be twice as wide as B. Should be an integer. scale applies in Rows, and to top-level Components in Blocks where fill_height=True. |
min_width int default: 160 | minimum pixel width, will wrap if not sufficient screen space to satisfy this value. If a certain scale value results in this Component being narrower than min_width, the min_width parameter will be respected first. |
interactive bool | None default: None | if True, will allow users to edit the dataframe; if False, can only be used to display data. If not provided, this is inferred based on whether the component is used as an input or output. |
visible bool default: True | If False, component will be hidden. |
elem_id str | None default: None | An optional string that is assigned as the id of this component in the HTML DOM. Can be used for targeting CSS styles. |
elem_classes list[str] | str | None default: None | An optional list of strings that are assigned as the classes of this component in the HTML DOM. Can be used for targeting CSS styles. |
render bool default: True | If False, component will not render be rendered in the Blocks context. Should be used if the intention is to assign event listeners now but render the component later. |
key int | str | None default: None | if assigned, will be used to assume identity across a re-render. Components that have the same key across a re-render will have their value preserved. |
wrap bool default: False | If True, the text in table cells will wrap when appropriate. If False and the |
line_breaks bool default: True | If True (default), will enable Github-flavored Markdown line breaks in chatbot messages. If False, single new lines will be ignored. Only applies for columns of type "markdown." |
column_widths list[str | int] | None default: None | An optional list representing the width of each column. The elements of the list should be in the format "100px" (ints are also accepted and converted to pixel values) or "10%". If not provided, the column widths will be automatically determined based on the content of the cells. Setting this parameter will cause the browser to try to fit the table within the page width. |
Class | Interface String Shortcut | Initialization |
---|---|---|
| "dataframe" | Uses default values |
| "numpy" | Uses type="numpy" |
| "matrix" | Uses type="array" |
| "list" | Uses type="array", col_count=1 |
Event listeners allow you to capture and respond to user interactions with the UI components you've defined in a Gradio Blocks app. When a user interacts with an element, such as changing a slider value or uploading an image, a function is called.
The Dataframe component supports the following event listeners. Each event listener takes the same parameters, which are listed in the Event Arguments table below.
Listener | Description |
---|---|
| Triggered when the value of the Dataframe changes either because of user input (e.g. a user types in a textbox) OR because of a function update (e.g. an image receives a value from the output of an event trigger). See |
| This listener is triggered when the user changes the value of the Dataframe. |
| Event listener for when the user selects or deselects the Dataframe. Uses event data gradio.SelectData to carry |
Parameter | Description |
---|---|
fn Callable | None | Literal['decorator'] default: "decorator" | the function to call when this event is triggered. Often a machine learning model's prediction function. Each parameter of the function corresponds to one input component, and the function should return a single value or a tuple of values, with each element in the tuple corresponding to one output component. |
inputs Component | list[Component] | set[Component] | None default: None | List of gradio.components to use as inputs. If the function takes no inputs, this should be an empty list. |
outputs Component | list[Component] | None default: None | List of gradio.components to use as outputs. If the function returns no outputs, this should be an empty list. |
api_name str | None | Literal[False] default: None | defines how the endpoint appears in the API docs. Can be a string, None, or False. If set to a string, the endpoint will be exposed in the API docs with the given name. If None (default), the name of the function will be used as the API endpoint. If False, the endpoint will not be exposed in the API docs and downstream apps (including those that |
scroll_to_output bool default: False | If True, will scroll to output component on completion |
show_progress Literal[('full', 'minimal', 'hidden')] default: "full" | If True, will show progress animation while pending |
queue bool | None default: None | If True, will place the request on the queue, if the queue has been enabled. If False, will not put this event on the queue, even if the queue has been enabled. If None, will use the queue setting of the gradio app. |
batch bool default: False | If True, then the function should process a batch of inputs, meaning that it should accept a list of input values for each parameter. The lists should be of equal length (and be up to length |
max_batch_size int default: 4 | Maximum number of inputs to batch together if this is called from the queue (only relevant if batch=True) |
preprocess bool default: True | If False, will not run preprocessing of component data before running 'fn' (e.g. leaving it as a base64 string if this method is called with the |
postprocess bool default: True | If False, will not run postprocessing of component data before returning 'fn' output to the browser. |
cancels dict[str, Any] | list[dict[str, Any]] | None default: None | A list of other events to cancel when this listener is triggered. For example, setting cancels=[click_event] will cancel the click_event, where click_event is the return value of another components .click method. Functions that have not yet run (or generators that are iterating) will be cancelled, but functions that are currently running will be allowed to finish. |
every float | None default: None | Run this event 'every' number of seconds while the client connection is open. Interpreted in seconds. |
trigger_mode Literal[('once', 'multiple', 'always_last')] | None default: None | If "once" (default for all events except |
js str | None default: None | Optional frontend js method to run before running 'fn'. Input arguments for js method are values of 'inputs' and 'outputs', return should be a list of values for output components. |
concurrency_limit int | None | Literal['default'] default: "default" | If set, this is the maximum number of this event that can be running simultaneously. Can be set to None to mean no concurrency_limit (any number of this event can be running simultaneously). Set to "default" to use the default concurrency limit (defined by the |
concurrency_id str | None default: None | If set, this is the id of the concurrency group. Events with the same concurrency_id will be limited by the lowest set concurrency_limit. |
show_api bool default: True | whether to show this event in the "view API" page of the Gradio app, or in the ".view_api()" method of the Gradio clients. Unlike setting api_name to False, setting show_api to False will still allow downstream apps as well as the Clients to use this event. If fn is None, show_api will automatically be set to False. |
