Answer 1

I am not sure about the size and which data you expect to use, but you could convert your table to a javascript array and then get the values from there.

Here is an example: Convert html table to array in javascript

Answer 2

mainTr = document.getElementById('1'),
firstTd = mainTr.getElementsByTagName('td')[0]
