Python Dash: Fitting a table and a graph in one row of a grid

问题

以下是您提供的代码的翻译部分：

我正在尝试将表格和图形放在网格的同一行中。我已经尝试通过设置 `style` 来调整它们的大小以适应，但由于某种奇怪的原因，表格被放置在图形的下方。

这是代码。是什么引起了这个问题？

I am trying to fit a table and a graph in one single row of a grid. I have tried to resize both of them to fit by setting the style, but for some odd reason the table is placed beneath the graph.

Here is the code. What is it caused by?

以下是您要翻译的代码部分：

For better control of the components of your Dash app, you should consider using `dbc.Col` components within `dbc.Row()` components. If you exchange your:

app.layout = html.Div([
    html.H1("USD", style={'textAlign': 'center'}),
    html.Div(children=[
        html.Div([dcc.Graph(id="1", figure=f1, style=aa),
                 dcc.Graph(id="2", figure=f2, style=aa)]),
        html.Div([

            html.Div([
                dash_table.DataTable(id="table", data=df_a.to_dict('records'), columns=[{"name": i, "id": i} for i in df_a.columns])], style=aa),

            html.Div([dbc.Container([
                dbc.Row(
                    dbc.Col([dropdown_country_a, dropdown_country_b], lg=6, sm=12)),
                dbc.Row(dbc.Col(dcc.Graph(id="asd"), lg=6, sm=12))])], style=aa)
        ])
    ])
])

With:

app.layout = html.Div([
    html.H1("USD", style={'textAlign': 'center'}),
    html.Div(children=[
        html.Div([dcc.Graph(id="1", figure=f1, style=aa),
                 dcc.Graph(id="2", figure=f2, style=aa)]),
        dbc.Row([dbc.Col([dropdown_country_a, dropdown_country_b], lg=6, sm=12)]),
        dbc.Row([dbc.Col([dash_table.DataTable(id="table", data=df_a.to_dict(
            'records'), columns=[{"name": i, "id": i} for i in df_a.columns])]), dbc.Col([dcc.Graph(id="asd")])])

    ])
])

然后，您将获得以下设置：

从这里，您可以使用dbc.Col组件的width属性调整您的应用程序的布局。

])

Then you'll get the following setup:

From here you can tweak the layout of your app with the width attribute of your dbc.Col components.
