go: how to input two-dimensional string array form keyboard??

[shine sun]

Firstly,  I try to input N and M from keyboard, creating a two-dimensional string array (var nums [N][M]string). Then, for i := 0; i < N; i++ , how to use fmt.Scanf to input M strings for each nums[i]? Finally, it can successfully  output the two-dimensional array nums. Thank you for helping!
