To use this, download, install, and activate the Extension like a regular WordPress plugin. Then, on the page where you want to show the table, insert the extended Shortcode

[table id=123 datatables_button_filter=true /]

and change the 123 to the desired table ID. After that, you can add HTML code like

<button class="table-123-filter" data-filterterm="searchterm">Button text</button>

anywhere on the page, to create a button that will run the filter when clicked. You will need to adjust the table ID (123 in the example) and the value for the data-filterterm attribute.
