Scroller is a plug-in for DataTables which enhances built-in scrolling features to allow large amounts of data to be rendered on page very quickly. This is done by Scroller through the use of a virtual rendering technique that will render only the part of the table that is actually required for the current view. Scroller assumes that all rows are of the same height (in order to preform the required calculations). Demo data in this example has 2,500 rows.

Scroller also supports DataTable's Buttons extension. Buttons can be initialised very easily though the buttons object which can be given as an array of the buttons that you wish to display. The B option in the dom parameter will instruct DataTables where the buttons should be placed in the document - in this case, at the top right. This example shows the copy, csv, excel, pdf and print buttons being used to display data export options for the DataTable.

Scroller will automatically integrate with DataTables in order to save the scrolling position of the table, if state saving is enabled in the DataTable (stateSave). This example shows that in practice - to demonstrate, scroll the table and then reload the page. When the page is reloaded, the table's state will be altered to match what they had previously set up.

This example shows a trivial use of the API methods that Scroller adds to the DataTables API to scroll to a row once the table's data has been loaded. In this case scroller().scrollToRow() is used to jump to row 1000. DataTables' info control element is automatically updated and shows the current visible row. Table height is configurable through scrollY string.
