How can I remove the WordPress term description column from WordPress term manage page (edit-tags.php)
You can use filter – manage_edit-post_tag_columns to remove WordPress term description column.
add_filter('manage_edit-taxonomy_name_columns', function ( $columns ) {
if( isset( $columns['description'] ) )
unset( $columns['description'] );
return $columns;
});
taxonomy_name should be your taxonomy name like post_tag
