verify-if-table-exists-in-database-wordpress.php

<?php 
include '../../../../wp-load.php';

global $wpdb;
$table_name = "wp_posts";

if($wpdb->get_var("SHOW TABLES LIKE '$table_name'") == $table_name) {
      //Your code here
}

?>

This will kill your website if you have a significant number of blogs.

Better use
$table_name = $wpdb->posts;
