Question about inequality join

dplyr has introduced inequality join since 1.1.0. Does datar have support for that?
I could not find any documentation about that.

I do not think it is the same thing.
I am refering to
https://dplyr.tidyverse.org/reference/join_by.html

This is also related: #189

It was experimental at that time. Looks like it's now official.

The join_by feature could be a bit tricky to implement since pandas does not have built-in support for inequality join.

There is a conditional_join in pyjanitor though.
