描述

Although PapaParse has a delimiter guessing mechanism, the method is far from being accurate. Actually, the research on this subject is on its way. Libraries like CleverCSV implements robust dialect sniffing strategies, backed by scientific research.

However, it is actually really difficult to separate the delimiters guessing mechanism from the Python's CleverCSV library. A recent research has pointed out a new universal method that can be integrated into whatever CSV parser, proved far more reliable than CleverCSV, as its research paper demonstrate.

The proposal is to implement the Table Uniformity Method, already implemented in Python and being considered to be implemented in Rust, by code porting. In this way, the wonderful PapaParse project will have an state of the art delimiter guessing strategy, improving significantly the automation in CSV processing.

研究方向: The issue proposes implementing the Table Uniformity Method for automatic delimiter detection in PapaParse. Start by reviewing the existing delimiter guessing mechanism in PapaParse's source code (likely in the main parser file). Then study the referenced Python implementation of the method (https://github.com/ws garcia/CSVsniffer/tree/main/python) and the research paper (https://doi.org/10.3233/DS 240062) to understand the algorithm. The goal is to port the method to JavaScript, integrating it into PapaParse's parsing logic. Look at any existing discussions in the issue comments for additional context.
