/**
* GtkTreeViewColumn:
*
* A visible column in a [class@Gtk.TreeView] widget
*
* The `GtkTreeViewColumn` object represents a visible column in a `GtkTreeView` widget.
* It allows to set properties of the column header, and functions as a holding pen
* for the cell renderers which determine how the data in the column is displayed.
*
* Please refer to the [tree widget conceptual overview](section-tree-widget.html)
* for an overview of all the objects and data types related to the tree widget and
* how they work together, and to the [class@Gtk.TreeView] documentation for specifics
* about the CSS node structure for treeviews and their headers.
*
* Deprecated: 4.10: Use [class@Gtk.ColumnView] and [class@Gtk.ColumnViewColumn]
* instead of [class@Gtk.TreeView] to show a tabular list
