Does anyonw know how I can add some pre-filled data to this table? I've commented what I'm trying to do but bascially:

Click add item button > creates new row with prefilled data (eg test - test - 1 - 1 - £1) > adds the whole thing to the total.

I've tried using http://www.w3schools.com/jsref/met_table_insertrow.asp this but can't seem to get anything working at all.
