Comment (by xkon):

 As mentioned by @TimothyBlynJacobs in [comment:25] filtering the column
 names is already provided. In the PR provided an extra action is added to
 the `column_default()` of `WP_Privacy_Requests_Table` to allow custom
 column data to be added as well.

 For consistency instead of using the `$this->request_type` from previous
 patches & comments, I'm using the `$this->screen->id` instead to keep the
 action & filter naming convention aligned.

 **Testing:**
 You can test the PR provided by adding this code in a mu-plugin and you
 should see the new columns being created on the Personal Data Export &
 Erasure tables.

 {{{
 <?php
 add_filter(
         'manage_export-personal-data_columns',
         function ( $columns ) {
                 $columns['my_export_column'] = __( 'Custom Column EX' );
                 return $columns;
         }
 );

 add_action(
         'manage_export-personal-data_custom_column' ,
         function( $columns, $item ) {
                 switch( $columns ) {
                         case 'my_export_column':
                                 echo 'Something';
                         break;
                 }
         },
         10,
         2
 );

 add_filter(
         'manage_erase-personal-data_columns',
         function ( $columns ) {
                 $columns['my_erase_column'] = __( 'Custom Column ER' );
                 return $columns;
         }
 );

 add_action(
         'manage_erase-personal-data_custom_column',
         function( $columns, $item ) {
                 switch( $columns ) {
                         case 'my_erase_column':
                                 echo 'Something Else';
                         break;
                 }
         },
         10,
         2
 );
 }}}
