Need advise on how to create extractor pattern for data in html table format?

Hi,

I am new to this. But very excited to learn more. I have a simple question with regards of how to create extractor pattern when my source html stores data in html table format ? Example,

Above is in html table format, I have tried to use dataRecord to extract the entire table, then use sub-extractor pattern to identify the first cell which is (Day 1, A), but I cant get the rest of the data for the Row 1 Record.

I think because the cell does not have some unique identifier for me to match the pattern...any suggestion?

thks in advance !
