The License file https://github.com/evrencoskun/TableView/blob/master/LICENSE and now the artifact are licensed with the MIT License

BUT some (a lot) of the source files like https://github.com/evrencoskun/TableView/blob/master/tableview/src/main/java/com/evrencoskun/tableview/TableView.java

have a copyright header of

Which is for Apache 2.0 License

I suggest aligning the copyright headers with the main License file. (If that is the correct license you want to use)

I suggest that you look at your editors copyright auto header generator and change that to the correct License

If a lot of the source files need changing is probably a background task to do when another change are made.
