In gtk+ ( C ):



void
gtk_tree_view_set_grid_lines(GtkTreeView *tree_view, GtkTreeViewGridLines grid_lines);

enum GtkTreeViewGridLines

typedef enum
{
GTK_TREE_VIEW_GRID_LINES_NONE,
GTK_TREE_VIEW_GRID_LINES_HORIZONTAL,
GTK_TREE_VIEW_GRID_LINES_VERTICAL,
GTK_TREE_VIEW_GRID_LINES_BOTH
} GtkTreeViewGridLines;


This for gtkmm ( C++ ):


void Gtk::TreeView::set_grid_lines(TreeViewGridLines grid_lines);


Maybe this will get rid of the column line. But it may also be theme dependent. I haven't tried this myself yet.
