Utilizing the column approach within Protractor

I've been going through the documentation trying to figure out exactly what the column method does, but I can't seem to find a clear explanation. Can anyone shed some light on its functionality?

Here's the code I'm working with:

var phoneNameColumn = element.all(by.repeater('phone in phones').column('phone.name'));
  var query = element(by.model('query'));

  function getNames() {
    return phoneNameColumn.map(function(elm) {
      return elm.getText();
    });
  }

  query.sendKeys('tablet'); //narrowing down the dataset for concise test assertions

  expect(getNames()).toEqual([
    "Motorola XOOM\u2122 with Wi-Fi",
    "MOTOROLA XOOM\u2122"
  ]);

column() is a helpful method for extracting columns from a repeater based on binding. In the context of a table created by a repeater, the columns represent the fields in your model, while the rows correspond to instances of the model.

For instance, if you need to retrieve all the book names from a repeater:

element.all(by.repeater('book in library').column('book.name'));

You can also target a specific row to fetch a single book name:

element(by.repeater('book in library').row(0).column('book.name'));
