JavaFX TableView: Select the whole TableColumn and get the index

Assume that we have a simple Tableview with 3 columns (A, B, C). Each Column contains some data which is not important at the moment.

I wondered if it would be possible to make only a whole column selectable (no matter where the user clicks in the column) and retrieve the ID and/or index of that column selected by the user?

For example, the user clicks somewhere in the area of column B. In that case the whole column should be marked and index 2 should be returned.

Any help would be appreciated ;)
