$post_columns(string[])

An associative array of columns (their keys and names). For example, the default array for “Posts” looks like this:

Array (
	[cb] => <input type="checkbox" />
	[title] => Title
	[author] => Author
	[categories] => Categories
	[tags] => Tags
	[comments] => <span class="vers comment-grey-bubble" title="Comments"><span class="screen-reader-text">Comments</span></span>
	[date] => Date
)

$post_type(string)

The post type slug, for example, post, news, product, and so on.

Examples

#1 Change a column name

Suppose you registered a post type named “Services” with the “service” slug and now want to rename the “Title” column to “Service name”:

add_filter( 'manage_posts_columns', 'change_title_in_table_services', 10, 2 );

function change_title_in_table_services( $post_columns, $post_type ) {
	if ( 'service' === $post_type ) {
		$post_columns['title'] = 'Service name';
	}

	return $post_columns;
}
