I used Smart TOC to add a directory to the HTML file exported by Typora, but I found that its directory recognition was inaccurate. He can only accurately recognize the first level title '<h1>', and cannot recognize other levels of titles properly. Moreover, the content appearing in the directory is from '<p><strong class=""><span>xxx</span></strong></p>'. This may cause exceptions in some files, but it can be displayed normally in some files.
