一、Reuable Comopnents

By writing our makup in Python, we can create complex reusable components like tables without switching contexts or languages.

from dash import Dash, html
import pandas as pd

df = pd.read_csv('https://raw.githubusercontent.com/GarciaShanCW/DATA/main/usa-agricultural-exports-2011.csv')

def generate_table(dataframe, max_rows=10):
    return html.Table([
        html.Thead(
            html.Tr([html.Th(col) for col in dataframe.columns])
        ),
        html.Tbody([
            html.Tr([
                html.Td(dataframe.iloc[i][col]) for col in dataframe.columns
            ]) for i in range(min(len(dataframe), max_rows))
        ])
    ])


app = Dash(__name__)

app.layout = html.Div([
    html.H4(children='US Agriculture Exports (2011)'),
    generate_table(df)
])

if __name__ == '__main__':
    app.run(debug=True)
