Remove column from WordPress users list

How to remove column from WordPress users list? You may don’t wish to show some column to the non-admin users with access to the users list, for example.
WordPress “Users” table has 6 built-in columns: checkbox for row selection, Username, Name, E-mail, Role, Posts. Every column has its ID.
Look as them are defined at the WP_Users_List_Table::get_columns() method of wp-admin/includes/class-wp-users-list-table.php, line #269:

$c = array(
	'cb'       => '',
	'username' => __( 'Username' ),
	'name'     => __( 'Name' ),
	'email'    => __( 'E-mail' ),
	'role'     => __( 'Role' ),
	'posts'    => __( 'Posts' )
);

If for example you need to remove E-mail column you should unset a column with ’email’ ID. Let’s go to the final step:

add_filter('manage_users_columns','remove_users_columns');
function remove_users_columns($column_headers) {
    if (current_user_can('moderator')) {
      unset($column_headers['email']);
    }
    
    return $column_headers;
}

We use manage_users_columns filter to achieve this purpose. This code removes ‘E-mail’ folder for users with ‘moderator’ role. Replace it with your own one.
In order to remove other column replace ’email’ column ID to that column ID: role, posts, etc.

Other variant for the list of roles:

add_filter('manage_users_columns','remove_users_columns');
function remove_users_columns($column_headers) {
    $roles = array('moderator', 'users-list-viewer');
    foreach($roles as $role) {
        if (current_user_can($role)) {
            unset($column_headers['email']);
            break;
        }
    }
    
    return $column_headers;
}

Another variant for the list of users ID:

add_filter('manage_users_columns','remove_users_columns');
function remove_users_columns($column_headers) {
    global $current_user;
    
    $users = array(27, 70530, 70531, 70532);
    
    if (in_array($current_user->ID, $users)) {
        unset($column_headers['email']);
    }    
    
    return $column_headers;
}

Put a selected variant of a code to your active theme functions.php file or into .php file at the wp-content/mu-plugins/ folder in order to start use it at your site.

A strange thing – manage_users_columns filter was not documented. I think that a reason is its complex definition. Look into the WP_List_Table class constructor:

add_filter( "manage_{$this->screen->id}_columns", array( $this, 'get_columns' ), 0 );

This shows that there are a lot of useful filters which may help to manage columns list of any WordPress items list: posts, pages, media library items, any custom post type. What you should know in order to use such filter is just a screen ID of that table list. For example:

List	Screen ID	Filter	Columns ID
Posts	edit-post	manage_edit-post_columns	cb, title, author, categories, tags, ‘taxonomy-‘ . $taxonomy, comments, date
Media	upload	manage_upload_columns	cb, title, author, categories, tags, ‘taxonomy-‘ . $taxonomy, parent, comments, date
Pages	edit-page	manage_edit-page_columns	cb, title, author, comments, date
Comments	edit-comments	manage_edit-comments_columns	cb, author, comment, response
Plugins	plugins	manage_plugins_columns	cb, name, description
Users	users	manage_users_columns	cb, username, name, email, role, posts

For custom post types you may use this filter: “manage_{$post_type}_posts_columns”.
