Welcome to the community. I guess you are referring to the click functionality in http://tabulator.info/docs/5.1/callbacks#cell
.
This is currently not supported. But please create a request on github. I believe this could be generally useful.
What is currently supported is row selection.
For example something like
import panel as pn
import pandas as pd
pn.extension("tabulator")
df = pd.DataFrame([[1, 2, 3], [4, 5, 6]], columns=['a', 'b', 'c'])
tbl = pn.widgets.Tabulator(df, selectable=1)
def update_selection(event):
return event
update_selection=pn.bind(update_selection, tbl.param.selection)
pn.Column(tbl, update_selection).servable()
