When using a multi-index dataframe with hierachical=True, Tabulator does not show anything in the index column.
As per docs at Tabulator — Panel v1.4.1
from bokeh.sampledata.population import data as population_data
pop_df = population_data[population_data.Year == 2020].set_index(['Location', 'AgeGrp', 'Sex'])[['Value']]
pn.widgets.Tabulator(value=pop_df, hierarchical=True, aggregators={'Sex': 'sum', 'AgeGrp': 'sum'}, height=200)
If you toggle an index however, you get the first index and it remains. You can’t go back to the blank index row.
I would like the first level to be displayed on the initial display. Not sure there is any way to control the state of the expansion.
