这个是实例的代码, 后面的代码里面有

import dash_html_components as html

html.Div, html.Table

这些东西, 然后我搜索了一下找到了 dash_html_components 这个文件夹, 但是文件夹是这样的, 没有看到 Table 或者 Div 这样的定义,这个问题是怎么处理的?

import dash

import dash_core_components as dcc

import dash_html_components as html

import pandas as pd

df = pd.read_csv(

'https://gist.githubusercontent.com/chriddyp/'

'c78bf172206ce24f77d6363a2d754b59/raw/'

'c353e8ef842413cae56ae3920b8fd78468aa4cb2/'

'usa-agricultural-exports-2011.csv')

def generate_table(dataframe, max_rows=10):

return html.Table(

# Header

[html.Tr([html.Th(col) for col in dataframe.columns])] +

# Body

[html.Tr([

html.Td(dataframe.iloc[i][col]) for col in dataframe.columns

]) for i in range(min(len(dataframe), max_rows))]

)

app = dash.Dash()

app.layout = html.Div(children=[

html.H4(children='US Agriculture Exports (2011)'),

generate_table(df),

dcc.Interval(

id='interval-component',

interval=1*1000, # in milliseconds

n_interval=0

)

])

if __name__ == '__main__':

app.run_server(debug=True)

我看了一下 init.py 的定义, 是不是把那些定义都写到 js 文件里面了。

import os as _os

import dash as _dash

import sys as _sys

from .version import version

_current_path = _os.path.dirname(_os.path.abspath(file))

_components = _dash.development.component_loader.load_components(

_os.path.join(_current_path, 'metadata.json'),

'dash_html_components'

)

_this_module = _sys.modules[name]

_js_dist = [{

"relative_package_path": "bundle.js",

"external_url": (

"https://unpkg.com/[email protected]{}"

"/dash_html_components/bundle.js"

).format(version),

"namespace": "dash_html_components"

}]

for component in _components:

setattr(_this_module, component.name, component)

setattr(component, '_js_dist', _js_dist)
