Use Gtk::CellRendererText#markup=.

Pango Text Attribute Markup Language is similer HTML/CSS and you can
apply it to Gtk::Widgets which have #markup= method.

http://developer.gnome.org/doc/API/2.0/pango/PangoMarkupFormat.html

---------------------------------------
require 'gtk2'

Gtk.init

model = Gtk::TreeStore.new(String)
tv = Gtk::TreeView.new(model)

cell = Gtk::CellRendererText.new
column = Gtk::TreeViewColumn.new("Title", cell, :markup => 0)
tv.append_column(column)

msg = %Q[
<b>bold</b>
<span foreground="#dddddd">Grey colored</span>
<u>Underlined</u>
]

2.times do
  iter = model.append(nil)
  model.set_value(iter, 0, msg)
end

window = Gtk::Window.new.add(tv).set_default_size(300,300).show_all
