How to read a dynamic web table value in Loadrunner

I have to read a value from a webtable and use that value to perform a search. I tried to use web_reg_find function but that requires a searchable text. In my scenario, I have to read a dynamic numerical-id and so i'm not able to use that function. Is there a way to read the column/row value (like in QTP)?
I don't want to use QTP in LR because that's limits our testing in different ways. Please suggest.
