This tutorial explains in detail how to efficiently embed HTML tables exported by Pandas in a web page. In view of the limitations of traditional client import methods, this article focuses on the method of using server-Side Includes (SSI) technologies such as PHP. Through specific steps and code examples, we aim to help developers understand and apply server-side solutions, ensuring seamless integration of table content and laying the foundation for subsequent client interactions (such as filtering).

To automatically refresh the page using meta tags in HTML, you need to add it in part, which will make the page refresh every 5 seconds; if you need to redirect, you can write it as, which means that you will jump to the specified URL after 5 seconds; the refresh time is in seconds, and 0 means refreshing or redirecting immediately; but this method is not conducive to SEO and may affect the user experience. It is recommended to use it as a temporary solution only when static hosting or the server cannot be configured. In modern development, JavaScript or WebSockets are recommended to achieve dynamic updates.

SVG graphics can be embedded directly into HTML files and implemented by writing SVG code inline in HTML. This method can completely control styles and interactions through CSS and JavaScript, and reduce HTTP requests. 1. Use inline SVG code: Copy and paste elements from the SVG file into the desired location in the HTML, like in the example to create a red circle and overlay white text. 2. Beautify SVG with CSS: Since SVG belongs to the DOM structure, you can set the style through CSS, such as adding the transition effect of the circle color changing from blue to green when hovering. 3. Implement responsive design: remove the fixed width and height attribute, and use the viewBox attribute to set the width and height ratio with CSS to make the SVG on different screens

The way to write HTML comments is to wrap the content with 1. It can be used to add instructions to developers, such as marking the starting position of the navigation menu; 2. The code can be temporarily commented for debugging, such as hidden paragraphs; 3. The page structure can be divided to improve readability, such as identifying the head, main body, and tail area; it should be noted that the comments will not be displayed on the page but can be seen in the source code, cannot be nested and double hyphens are avoided. Correct use can significantly improve code maintenance.
