具有多个标题或合并列的表Plotly Python

Question

我正在尝试使用回调函数在表中构建表，我正在使用Go.Table但无法创建多个标题

Answer 1

If I was correct read docs , you can not create multiple headers.

First possible solution is to move headers to values:

import plotly
import plotly.graph_objs as go

trace = go.Table(
    header=dict(values=['Version', 'Baseline', 'Promo', 'VDP+']),
    cells=dict(values=[['', '08/20 to 08/27','08/13 to 08/20', '08/06 to 08/13',\
                        '07/30 to 08/06'],
                       ['Current Month: Aug 18', '', '', '', ''],
                       ['Current Month: Aug 18', '', '', '', ''],
                       ['Current Month: Aug 18', '', '', '', '']]))

data = [trace] 
plotly.offline.plot(data, filename = 'basic_table.html')

Looks like:

But you can not operate with them such as columns what is not great.

Second possible solution is to specify prefix (or suffix - depends what would you like more):

import plotly
import plotly.graph_objs as go

trace = go.Table(
    header=dict(values=['Version', '.Baseline', '.Promo', '.VDP+'], 
                prefix = ['','Current_Month:_Aug_18', 'Current_Month:_Aug_18',\
                          'Current_Month:_Aug_18'],
                ),
    cells=dict(values=[['08/20 to 08/27', '08/13 to 08/20', '08/06 to 08/13', \
                        '07/30 to 08/06'],
                       ['', '', '', ''],
                       ['', '', '', ''],
                       ['', '', '', '']]))

data = [trace] 
plotly.offline.plot(data, filename = 'basic_table.html')

And in this case, you can add your columns as prefix or suffix.

Looks like:

Update: Yep, you can create an empty row (just do not specify headers ):

Update: Currently I found the way to get what you need:

import plotly
import plotly.graph_objs as go

trace = go.Table(
    header=dict(values=[['Version', ''],
                        ['Baseline', 'Current Month: Aug 18'],
                        ['Promo', 'Current Month: Aug 18'],
                        ['VDP+', 'Current Month: Aug 18']]),
    cells=dict(values=[['08/20 to 08/27', '08/13 to 08/20', '08/06 to 08/13', \
                        '07/30 to 08/06'],
                       ['', '', '', ''],
                       ['', '', '', ''],
                       ['', '', '', '']]))

data = [trace] 
plotly.offline.plot(data, filename = 'basic_table.html')

Looks like:

I can not hide one line but the whole lines of headers(add line = dict(width=0) after headers values): Or set the color of lines but for all the lines again (with same results as above)
