Is classical wordpress eidtor a good option for me to include a large table with a large number of images on my webpage?

I am a beginner at using WordPress for my website. I generally design my website using the classical editor provided by WordPress and by installing very few plugins such as Beaver Builder and code syntax highlighter. I am not well aware of doing coding in PHP, CSS, etc.

Currently, I need to include a large table of (thousands of) rows with at least 7 columns. Some of the columns include images and the others include strings are numbers.

I can able to generate the table using python code, I just want to place the output into the web page.

The browser is getting slow when I try to copy thousands of lines using the WordPress classical editor. So I am getting the doubt whether the classical editor is a good option to do my task.

Is the classical editor of WordPress is a good option to work for in my task or do I need to work with any other plugin?
