刚编好的完全符合你的要求你看看可以不

import java.util.*;

public class Test {

public static void main(String[] args) {
System.out.println("输入列数");
int col = new Scanner(System.in).nextInt();
System.out.println("输入行数");
int row = new Scanner(System.in).nextInt();
for(int i=1; i<=row; i++) {
for(int j=1; j<=col; j++) {
if(i%2 == 1)
System.out.print(j + col * (i-1) +" ");
else
System.out.print(col - (j-1) + col * (i-1) +" ");
}
System.out.println("");
}

}

}
