# An easy problem

In this problem you need to make a multiply table of N * N ,just like the sample out. The element in the ith row and jth column should be the product(乘积) of i and j.

The first line of input is an integer C which indicate the number of test cases.

Then C test cases follow.Each test case contains an integer N (1<=N<=9) in a line which mentioned above.

HintThere is no blank space at the end of each line. 

import java.util.Scanner;
public class Main{
public static void main(String[] args) {
Scanner input=new Scanner(System.in);
int N=input.nextInt();
while(N-->0){
int n=input.nextInt();
for(int i=1;i<=n;i++){
System.out.print(i);
for(int j=2;j<=n;j++){
System.out.print(" "+i*j);
}
System.out.println();
}
}
}
}
