Subject: [javascript] rowIndex in Table


Hi All,

I've beat my head against the wall for a couple of days now so it's time 
to ask for help.

Background:
I have a table which I construct on the fly. Simple enough, it just lets 
users record line items on an invoice and when they are through with one 
line they click a button and the line gets added to a dynamic table.  They 
repeat until all lines have been entered - could be 1 line coule be 100.

Problem:
The table contains a delete button in case the user blew the entry.  To 
know which row to delete I need the rowIndex of the button they clicked. 
Do you think I can find a way to get that?  I've tried 100 different 
syntaxes, scoured all the documentation I can find and just can't get it. 
I can find everything but how to get rowIndex.

Could anyone give me a hand with this, I'm just baffled.  Thanks very much 
in advance for anything you can suggest.

Regards,
Peter
