i have tons of data that i would like to highlight only those cell that fulfill some criteria, said value < 0.100. Please advice.
Conditional Formatting is what you are looking for.
The above answers are correct, but I would add that if I recall correctly you can have unlimited conditional formatting on the same cell(s) in Excel 2007, but only three conditions pre-Excel 2007.
上面的答案是正確的,但我想補充一點,如果我沒記錯,你可以在Excel 2007中的相同單元格上有無限的條件格式,但只有三個條件在Excel 2007之前。
