    If the new custom column is only for the default post type, then it needs to check the post type.

    function my_add_new_columns($columns) {
    $post_type = get_post_type();
    if ( $post_type == 'post' ) {
        $new_columns = array(
            'my_featured' => esc_html__( 'Featured', 'text_domain' ),
        );
        return array_merge($columns, $new_columns);
    }
}
add_filter( 'manage_posts_columns',  'my_add_new_columns' );

    To add a custom column, hook into this filter, and add an item to the $post_columns array. The key should be a string ID, and the value should be the human-readable text to display in the column’s header.

    <?php
namespace DemoPlugin;

const COLUMN_ID = 'publisher';

/**
 * Register the custom column.
 *
 * @param array $columns Existing columns.
 * @return array Columns with custom column added.
 */
function register_column( array $columns ) : array {
	$columns[ COLUMN_ID ] = __( 'Publisher', 'demo-plugin' );
	return $columns;
}
add_action( 'manage_posts_columns', __NAMESPACE__ . '\\register_column' );

// You will likely also want to hook into 'manage_posts_custom_column' to
// output the column's value.
function render_column( string $column_id ) {
	if ( $column_id !== COLUMN_ID ) {
		return;
	}

	$post = get_post();
	echo esc_html( get_post_meta( $post->ID, '_demo_publisher', true ) );
}
add_action( 'manage_posts_custom_column',  __NAMESPACE__ . '\\render_column' );

    Example: To add custom featured image thumbnail column in the post.

    function wpdocs_posts_thumb_columns( $columns ) {

    );
    return array_merge( $columns, $post_new_columns );
}
add_filter( 'manage_posts_columns', 'wpdocs_posts_thumb_columns', 5 );

function wpdocs_posts_custom_columns( $column_name, $id ) {
    if ( 'post_thumbs' === $column_name ) {
        the_post_thumbnail( 'thumbnail' );
    }
