如何在 Dash 中使表格的单元格值超链接？ （使用 Plotly、Dash、Pandas 等）

Question

我想将“JobLink”列下的单元格值设置为超链接。当我单击此链接时，它应该导航到新选项卡/窗口中的链接。请帮忙如何实现？ 该表在 Dash 中显示，我发现很难使其超链接。 附截图：https://i.stack.imgur.com/yIAqH.png [![在此处输入图像描述][2]][2] [![Dash 中显示的数据表 http://127.0.0.1:80/ ][1]][1]

我们可以在 Markdown 单元格中使用 HTML 内容。

MWE：

from dash import Dash
from dash_table import DataTable
import pandas as pd

df = pd.DataFrame(
    {
        "Job Link": [
            "<a href='https://www.google.com/' target='_blank'>https://www.google.com/</a>",
            "<a href='https://www.google.com/' target='_blank'>https://www.google.com/</a>",
            "<a href='https://www.google.com/' target='_blank'>https://www.google.com/</a>",
        ]
    }
)

app = Dash(__name__)

app.layout = DataTable(
    id="table",
    data=df.to_dict("records"),
    columns=[
        {"id": "Job Link", "name": "Job Link", "presentation": "markdown"},
    ],
    markdown_options={"html": True},
)

if __name__ == "__main__":
    app.run_server()
