Everywhere I’ve checked for this information suggested installing additional plugins to enable support for this feature, or said that it was a lengthy and complicated process … but that is not true.
Simply set show_admin_column to true on your taxonomy in functions.php:
function main_taxonomy() {
register_taxonomy(
'my_tax',
array('as_many', 'taxonomies', 'as_you_need'),
array(
'label' => __( 'Tax Types' ),
'rewrite' => array( 'slug' => 'my_tax' ),
'hierarchical' => true,
'query_var' => true,
'show_ui' => true,
'show_in_menu' => true,
'show_admin_column' => true, // where the magic happens
)
);
}
add_action ( 'init', 'main_taxonomy' );
