Create a particular {x,y} list [duplicate]

Question

How is it possible to create a list of {x,y} points as the following one:

list={{1,1},{1,2},...,{1,100},{2,1},{2,2},...,{2,100},...,{100,1},{100,2},...,{100,100}}

Thanks

Hi, I was using Range, but it doesn't work for 2D lists. However, you answer gives my some additional brackets that are unwanted, like this: {{{1,1},{1,2},...,{1,100},{2,1},{2,2},...,{2,100},...,{100,1},{100,2},...,{100,100}}}. I've found the way with Flatten[]. Thanks for your help! — MicheleG, Commented Feb 27, 2017 at 16:45
Not an exact duplicate but a more general topic. Let me know if you disagree with closing. — Kuba, Commented Feb 27, 2017 at 16:46
@Michele You need to Flatten the result; consider Flatten[Table[{i, j}, {i, 1, 100}, {j, 100}], 1]. More in general, also take a look at the proposed duplicate. — MarcoB, Commented Feb 27, 2017 at 16:49

Tuples[Range[100], 2]

or using Table as mentioned in the comment

It is worth noting that the method relying on Tuples is 10-12 times faster than Table
