Common errors in generating directories

Format error: Some people often ignore the format requirements of the table of contents, such as not uniformly using Arabic numerals or Roman numerals for grading, or ignoring the relationship between the titles of each level and their corresponding page numbers. These format errors may lead to the failure of directory generation, making it difficult for readers to find the content of the article.

Irregular title naming: Some people have irregular title naming in the text, which makes the computer directory generation algorithm unable to accurately identify its hierarchical relationship, resulting in errors in the generated directory. For example, in the same semantic context, some people may use different titles, such as "summary", "conclusion" and "research summary", which will make the program go wrong and make it impossible to generate the directory correctly.

Typesetting: When writing an article, some people may mark the titles of different levels with different formats, such as bold, small font or mixed Chinese and English. This will make the computer unable to recognize the hierarchical relationship of each title, which will lead to directory generation errors.
