Plotly Python-更改表格的字体

我有一张用plotly制作的表格，我想把字体改为“Gill Sans”

我很难改变它。这可能吗

这是我的代码：

groupA = new_df.groupby('Call').agg({'TotalGrantValue':sum, 'FirstReceivedDate':'count'}).rename(columns={'FirstReceivedDate':'Count'})
groupA['TotalGrantValue'] = groupA['TotalGrantValue'].map('{:,.2f}'.format)

colorscale = [[0, '#7f7f7f'],[.5, '#F1EDED'],[1, '#ffffff']]

table = ff.create_table(groupA, index=True,colorscale=colorscale, height_constant=14, index_title='Date')
table.layout.width = 700
for i in range(len(table.layout.annotations)):
    table.layout.annotations[i].font.size = 10
plotly.offline.iplot(table, config={"displayModeBar": False}, show_link=False, filename='index_table_pd')

您需要定义布局参数，如中所述

在同一页中，有一个示例代码可以帮助您：

layout = go.Layout(
    xaxis=dict(
        title='AXIS TITLE',
        titlefont=dict(
            family='Arial, sans-serif',
            size=18,
            color='lightgrey'
        ),
        showticklabels=True,
        tickangle=45,
        tickfont=dict(
            family='Old Standard TT, serif',
            size=14,
            color='black'
        ),
        exponentformat='e',
        showexponent='All'
    ),
    yaxis=dict(
        title='AXIS TITLE',
        titlefont=dict(
            family='Arial, sans-serif',
            size=18,
            color='lightgrey'
        ),
        showticklabels=True,
        tickangle=45,
        tickfont=dict(
            family='Old Standard TT, serif',
            size=14,
            color='black'
        ),
        exponentformat='e',
        showexponent='All'
    )
)
fig = go.Figure(data=data, layout=layout)
py.iplot(fig, filename='axes-labels')
