Can jQuery supply the text of a table element when the user double clicks on it ?

Can jQuery supply the text of a table element when the user double clicks on it ?

I am new to jQuery, but think it might be able to solve a problem for me.

I am displaying large tables of information on web pages.  These are generated from a database.

I would like to offer the user the chance to double click on any particular cell in the table (which will be delimited by <td> and </td>) to drill down for more information.  To make this work, I need to be able to retrieve the text in the cell.  I can't find a jQuery selector that will let me do this.  I can get the correct routine to fire when someone double clicks on an "enabled" cell, but can not then retrieve the text.

Any ideas - even if it's "you can't do this with jQuery" - will be gratefully received.
