HELP.. BUTTONCELL - How to put Image on ButtonCell??????

[Joshua Carey]

I have a table that has a button on everyrow.  This button actually launches a PDF browser to display an image.  How can I put an ICON IMAGE on a BUTTONCELL object?  I have a regular PUSHBUTTON outside of my table that I am able to load an IMAGE on, but I don't see any options in GWT to use PUSHBUTTON within my table.  So currently I am using a BUTTONCELL to put a button on each row of my table.  CAN I PUT A ICON IMAGE on the BUTTONCELL?  If not, how can I put a button on every row in my table that DOES have an image?

Thanks,

Joshua
