How to select specific Row, Col ( TR, TD)

How to select specific Row, Col ( TR, TD)

Hi ,I´m totally new with jQuery as of today.

What i´m needing is to select a specific row inside a table  and a specific cell within that row.

The only things i know about the row is its position within the table. It occupies row #14 and the cell is #0
within that row.

how can I do that?

Thanks in advance
Mauricio
