What exactly do "FilterProperty" and "FilterValue" in the columns properties of a DataGrid

hello, I have a Inline DataGrid, and when I click on "Edit columns" I see all my columns and their property.
Each column has "FilterProperty" and "FilterValue", and I'm not sure how these are used and what exactly are they for.

Could someone provide me with an example so I can understand it better? Thank you
