Configure a link column in st.dataframe or st.data_editor.
The cell values need to be string and will be shown as clickable links. This command needs to be used in the column_config parameter of st.dataframe or st.data_editor. When used with st.data_editor, editing will be enabled with a text input widget.
| Function signature[source] | |
|---|---|
st.column_config.LinkColumn(label=None, *, width=None, help=None, disabled=None, required=None, pinned=None, default=None, max_chars=None, validate=None, display_text=None) | |
| Parameters | |
label (str or None) | The label shown at the top of the column. If this is None (default), the column name is used. |
width ("small", "medium", "large", or None) | The display width of the column. If this is None (default), the column will be sized to fit the cell contents. Otherwise, this can be one of the following:
|
help (str or None) | An optional tooltip that gets displayed when hovering over the column label. If this is None (default), no tooltip is displayed. |
disabled (bool or None) | Whether editing should be disabled for this column. If this is None (default), Streamlit will decide: indices are disabled and data columns are not. If a column has mixed types, it may become uneditable regardless of disabled. |
required (bool or None) | Whether edited cells in the column need to have a value. If this is False (default), the user can submit empty values for this column. If this is True, an edited cell in this column can only be submitted if its value is not None, and a new row will only be submitted after the user fills in this column. |
pinned (bool or None) | Whether the column is pinned. A pinned column will stay visible on the left side no matter where the user scrolls. If this is None (default), Streamlit will decide: index columns are pinned, and data columns are not pinned. |
default (str or None) | Specifies the default value in this column when a new row is added by the user. This defaults to None. |
max_chars (int or None) | The maximum number of characters that can be entered. If this is None (default), there will be no maximum. |
validate (str or None) | A JS-flavored regular expression (e.g. "^https://.+$") that edited values are validated against. If the user input is invalid, it will not be submitted. |
display_text (str or None) | The text that is displayed in the cell. This can be one of the following:
For more complex cases, you may use Pandas Styler's format function on the underlying dataframe. Note that this makes the app slow, doesn't work with editable columns, and might be removed in the future. Text formatting from column_config always takes precedence over text formatting from pandas.Styler. |
Examples
import pandas as pd import streamlit as st data_df = pd.DataFrame( { "apps": [ "https://roadmap.streamlit.app", "https://extras.streamlit.app", "https://issues.streamlit.app", "https://30days.streamlit.app", ], "creator": [ "https://github.com/streamlit", "https://github.com/arnaudmiribel", "https://github.com/streamlit", "https://github.com/streamlit", ], } ) st.data_editor( data_df, column_config={ "apps": st.column_config.LinkColumn( "Trending apps", help="The top trending Streamlit apps", validate=r"^https://[a-z]+\.streamlit\.app$", max_chars=100, display_text=r"https://(.*?)\.streamlit\.app" ), "creator": st.column_config.LinkColumn( "App Creator", display_text="Open profile" ), }, hide_index=True, )
