Regex Tester & Validator

This regular expression is designed to match an HTML `<table>` element containing an `id` attribute, capturing the tag's attributes and the table's inner HTML content. It uses lazy matching (`.*?`) to locate the `id` attribute anywhere within the opening tag, followed by a literal double quote (with an odd `"{0}"` construct that effectively evaluates to a single double quote). It is typically used for basic HTML scraping or parsing tasks where you need to extract specific tables by their identifier, though it is not recommended for parsing complex or nested HTML.
