DataTables processing Option

  • Last Updated : 31 May, 2021

DataTables is jQuery plugin that can be used for adding interactive and advanced controls to HTML tables for the webpage. This also allows the data in the table to be searched, sorted, and filtered according to the needs of the user. The DataTable also exposes a powerful API that can be further used to modify how the data is displayed.

The processing option is used to specify whether the processing indicator is enabled or not. This indicator is shown when the DataTable is busy doing some operation that would take some time. This is useful for tables that have a huge amount of data and take a lot of time to perform any operation. This indicator would be able to notify the user that an operation is going on and has not got stuck. A true value displays the indicator and a false value removes it.
