Fix for #19860 (comment)

I do not know how to test the changes as those were working with the doc builder previously.

@javiereguiluz Looks like this change did not work. I'm wondering how can I test the change before it goes live? What is the official site using? Why the rendering is that much different?

@homersimpsons that's odd because you applied the same trick as I did in my PR. The table I changed is being rendered as expected. See https://symfony.com/doc/current/notifier.html#sms-channel

I can't see any difference in your RST table ... but when rendered it doesn't work as expected: https://symfony.com/doc/current/reference/formats/expression_language.html#operators-precedence

The best way to render the docs locally is to:

• Clone this repo
• cd _build/
• composer install
• php build.php

The generated docs use a very different design ... but just browse the page reference/formats/expression_language.html and check if the HTML structure of the generated table is correct.

check if the HTML structure of the generated table is correct

I did not check the HTML structure, I will check this.
