Hi @marketemp
You can find information of formatting numerical data in a Dash DataTable here: https://dash.plotly.com/datatable/typing
and in this thread:
https://community.plotly.com/t/dash-table-formatting-decimal-place
When the column type is set to numeric and it’s formatted as described in the links, then the sort_action=native works and there is no need to do custom sorting.
