WP_List_Table::get_sortable_columns()

Gets a list of sortable columns.

Description

The format is:

  • 'internal-name' => 'orderby'
  • 'internal-name' => array( 'orderby', 'asc' ) – The second element sets the initial sorting order.
  • 'internal-name' => array( 'orderby', true ) – The second element makes the initial order descending.

Return

(array)

More Information

This method should be overridden to return an associative array of columns that you want to make sortable. The associative array should follow the format 'column_slug'=>array('sortby',true), where the second property states whether the field is presorted. This is frequently used to provide part of the _column_headers property.
