When working with a blog post, you may or may not use a tag to tag your post. in my case, I used a long list of tags for each post and when it showed under the posts list, it is really annoying to see a long list of tags. I decided to remove them so I can browse the posts list more quickly and with less scrolling.

here’s a quick solution if you want to remove columns in the posts list
add the following code to your functions.php

if( !function_exists('wp_remove_wp_columns') ):
function wp_remove_wp_columns( $columns ) {
  unset($columns['tags']);
  return $columns;
}
function wp_remove_wp_columns_init() {
add_filter( 'manage_posts_columns' , 'wp_remove_wp_columns' );
}
add_action( 'admin_init' , 'wp_remove_wp_columns_init' );
endif;

Here’s the before and after the result from the added code.

you certainly can notice how many spaces and scrolling were saved.
