question (ipyvuetify): Specify different colors for a button in each row of the DataTable

[imanbabaei]

I am trying to link the ipyvuetify data table with a FigureWidget in Plotly. I wanted to display the colors of each line in the corresponding row in the table. I tried to use v_slots, but I couldn't customize the color for each row. I know the hex code every time I plot.

import ipyvuetify as v
import  plotly.express as px

class Figure_Data(v.DataTable):
    def __init__(self, *args, **kwargs):
        self.colors = px.colors.qualitative.Plotly   
        # ['#636EFA', '#EF553B', '#00CC96', '#AB63FA', '#FFA15A', '#19D3F3', '#FF6692', '#B6E880', '#FF97FF', '#FECB52']
        self.color_id = 0

        item_key = 'id'
        dense = True
        style_ = 'width:30%'
        hide_default_footer=True
        show_select=True

        super().__init__(item_key=item_key,
                         dense=dense,
                         style_=style_,
                         hide_default_footer=hide_default_footer,
                         show_select=show_select,
                         *args, **kwargs)

         # a header 
        self.headers = [
            { 'text': 'Name', 'value': 'name', 'width':'75%'},
            { 'text': 'Unit', 'value': 'unit', 'width':'20%'},
            { 'text': 'Color', 'value': 'color', 'width':'5%', 'sortable':False},
        ]

        # 2 initial items
        self.items = [
            {
                'name' : 'Data 1',
                'unit' : '-',
                'color': '#636EFA', # <-- color code
                'id'   : 0,
            },
            {
                'name' : 'Data 2',
                'unit' : '-',
                'color': '#EF553B',
                'id'   : 1,
            },
        ]

        self.v_slots=[{
                      'name': 'item.color',
                      'variable': 'color',
                      'children':  v.Btn(color='color', #?
                                         block=True,
                                         ripple=False, 
                                         elevation=2, 
                                         style_='height:80%; overflow: hide')
                }]

my_table = Figure_Data()
my_table

I know this is possible in Vue. (https://vuetifyjs.com/en/components/data-tables/#item) Is there any way to get the value of the color row using v_slots in ipyvuetify?

The slot functionality of ipyvuetify does not have feature parity with Vue. You can't make use of the variables passed in the slot from python.

You can work around this by using the template version of ipyvuetify: https://ipyvuetify.readthedocs.io/en/latest/template_usage.html
