Mange users columns

Add columns:

function new_modify_user_table( $column ) {
    $column['phone'] = 'Phone';
    $column['xyz'] = 'XYZ';
    return $column;
}
add_filter( 'manage_users_columns', 'new_modify_user_table' );

function new_modify_user_table_row( $val, $column_name, $user_id ) {
    switch ($column_name) {
        case 'phone' :
            return get_the_author_meta( 'phone', $user_id );
        case 'xyz' :
            return '';
        default:
    }
    return $val;
}
add_filter( 'manage_users_custom_column', 'new_modify_user_table_row', 10, 3 );

Remove columns:

$c = array( ‘cb’ => ‘<input type=”checkbox” />’, ‘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;
}
