I've to write code for:

Multiplication Tables  Description: Print out the grade school multiplication table upto 12*12

I'd written the code:

public class tables {
    public static void main(String[] args) {
        //int[][] table = new int[12][12];
        String table="";
        for(int i=1; i<13; i++){
            for(int j=1; j<13; j++){
                //table[i-1][j-1] = i*j;
                table+=(i*j)+" ";
            }
            System.out.println(table.trim());
            table="";
        }
    }
}

But the problem is with the output format. I need the output in a matrix like fashion, each number formatted to a width of 4 (the numbers are right-aligned and strip out leading/trailing spaces on each line). I'd tried google but not find any good solution to my problem. Can anybody help me out?
