Behavior unexpected

so the datatable has been pre-filtered and i plan to stop the datatable header filter event. But once i attempt to type in the datatable header filter, the datatable reverted my initial filter instead of doing nothing (which is intended). Need help.

Hello @Human,
Please note that onBeforeFilter not only prevents filtering, but also resets it, because of this, your initial filter disappears.

Also, as a solution, you can upload data to the dataCollection and filter it. In the table, filters will work only with data that came from the dataCollection (with filtering results).
In addition, table filters can be disabled either through onBeforeFilter or combined with dataCollection filtering.
