Conditional formating numerical column

I think you just need to change filter_query to filter. In my case, I also set the filter (as you defined) on the style_cell_conditional parameter (vice style_data_conditional).

Also, based on the documentation,

To use even/odd or other styling based on row_index you must use style_data_conditional

I suspect the use of style_data_conditional much include a reference to the row index, but I’m not certain.
