Detecting mouse click in GtkTable

["Ian Puleston" <ian underpressuredivers com>]

Hi,

I have a GtkTable displaying some data, and I want to pop up a menu when the
user right-clicks a column, dependant on which column the user clicked in.
Is there a reasonably easy way to detect which column of a table a mouse
click was in?

Or (better) is there a way to set a mouse-click signal handler per column,
or per cell of the table?
