 There is a special case for remote pagination, even you only specified the pagination need to handle as remote, `react-bootstrap-table2` will handle all the table changes(filter, sort etc) as remote mode, because `react-bootstrap-table2` only know the data of current page, but filtering, searching or sort need to work on overall data.

+`true` to indicate your bootstrap version is 4. Default version is 3.

 ### <a name='loading'>loading - [Bool]</a>
 Telling if table is loading or not, for example: waiting data loading, filtering etc. It's **only** valid when [`remote`](#remote) is enabled.
 When `loading` is `true`, `react-bootstrap-table2` will attend to render a overlay on table via [`overlay`](#overlay) prop, if [`overlay`](#overlay) prop is not given, `react-bootstrap-table2` will ignore the overlay rendering.
