Is is possible to style a cell based on the info that is in the cell next to it?
I would like to get the same color to match the cell to the right
Sure - the easiest way is to apply the same formatting to the column and the one to it’s left, for example:
import dash
import dash_table
import pandas as pd
import numpy as np
df = pd.DataFrame(np.random.randn(6,4), columns=list('ABCD'))
app = dash.Dash(__name__)
app.layout = dash_table.DataTable(
id='table',
columns=[{"name": i, "id": i} for i in df.columns],
data=df.to_dict('records'),
style_data_conditional=[
{
'if': {
'filter_query': '{C} > 0',
'column_id': ['B', 'C']
},
'backgroundColor': 'dodgerblue',
'color': 'white'
},
]
)
if __name__ == '__main__':
app.run_server(debug=True)
And note - ability to use a list for column_id , row_index , and header_index was added in Dash 1.12.0
Thank you so much!!! This worked great and gave me lots of good ideas on how to use formatting. Great help!!
Super - glad it helped! 
A lot of great examples were added to the tutorial recently. The latest release had many cool new features for data tables.
