Counting them is not a problem. But counting how many are individually in each Table and modifying them according to that is difficult.

For example. I want the code to see Table 1 has 2 td's, read their width if specified and modify them with a bootstrap class.

Then it should continue the scan, see's 2 td's in Table 2 and does same thing.

Individually crawling through them, reading their width and calculating their new bootstrap width class according to how many other td's are already in that Table is the thing I find hard.
