Nobody is suggesting that you should be an expert on data frames "through divine intervention". But the place to expect to learn about those things is the many articles, tutorials, courses, and books on the subject, not the website of one specific new tool in the space.
If you're really interested in learning about this, a fairly canonical place to start would be "Python for Data Analysis"[0] by Wes McKinney, the creator of pandas and one of the creators of the arrow in-memory columnar data format that most of these projects build atop now.
This is a (multiple-) book length topic, not a project landing page length topic.
"Python for Data Analysis 2nd ed" (Wes McKinney, 2018)
If you want to up your skills in this area, Wes McKinney's "Python for Data Analysis" is pretty great.
And Wes (the creator of the Pandas library) has made the book available for free on his website!
