Nested for each

Question

I have a table of data like this. 
 
 1st row contains 3 data,2nd row contains 1 and 3rd row contains 4 like this. 
 I want to apply a nested for each loop for each data of each row and want to apply a rule on each data field. 
 I want to return the whole set of data after applying the rule on each data 
 
 How can I achieve this? 
 Thanks in advance

Hi digantas  adding to   Justin Watts  comment, also if you want to hold the values of nested foreach , you can define a local variable on top load() and within foreach you can define an another load() where for each iteration you need to append fv!item to local variable. 
 But this approach will cause you performance issue. I recommend, if these data are coming from db, and If they have any relationship, then try to join them and then perform single level of foreach instead of nested. 
 Hope this will help you.
