Hi Naren,
I didn't understand completely your problem. But if you want to show IL data fist and then NL data when both of these data is returned from single object, instead of applying formula, try placing a copy of same cross-tab table side by side and filter table 1 for IL values and table 2 values for NL values. You can hide repeating row value and place both table side by side using relative positioning so that it will look like a single table always.
for value "0" for null values, try if(isnull()) formula.
hope it helps.
