Regex Tester & Validator

This regular expression captures an entire HTML `<table>` element, including its opening tag, closing tag, and all content in between. It uses the character class `[\s\w\W]` to match absolutely any character, allowing it to span across multiple lines. It is commonly used for extracting HTML tables during web scraping or data parsing tasks, though it may greedily over-match if multiple tables exist without proper nesting.
