# Description @fdncred found another histogram based algorithm to detect columns, and rewrite it in rust: https://github.com/fdncred/guess-width I have tested it manually, and it works good with `df`, `docker ps`, `^ps`. This pr is going to use the algorithm in `detect columns` Fix: #4183 The pitfall of new algorithm: 1. it may not works well if there isn't too much rows of input 2. it may not works well if the length of value is less than the header to value, e.g: ``` c1 c2 c3 c4 c5 a b c d e g h i j k g a a q d a v c q q | detect columns ``` In this case, users might need to use ~~`--old`~~ `--legacy` to make it works well. # User-Facing Changes User might need to add ~~`--old`~~ `--legacy` to scripts if they find `detect columns` in their scripts broken. # Tests + Formatting Done # After Submitting NaN |
