 In order for filtering and sorting to work you need to set their modes to `server`.
 You can find out more information about how to do that on the [server-side filter page](/x/react-data-grid/filtering/#server-side-filter) and on the [server-side sorting page](/x/react-data-grid/sorting/#server-side-sorting).
