jwebunit: how to assert that some row in a table contains the actual values

Question

Hi, My web page displays the following table( in an html format, but simplified here)

Item# Item_Description Price Status

100     COOKIE  $68.00 Eligible 
123     RADIO   $94.00 Eligible 
300 DIAPERS $54.00 Returned

How do I use jwebunit to make an assertion that there is some row in this table with Item#=300 and status = "Returned" . That would in this case be the third row in the table above.
