JAVA:

@Test
public void test11() {
for (int i = 1; i < 10; i++) {
for (int j = 1; j <= i; j++) {
System.out.print(i + "*" + j + "=" +i*j +" ");

}
System.out.println("\t");

}

python:

for i in range(1,10): 
    for j in range(1,i+1) :
        print("%d*%d=%2d" %(j,j,i*j),end="\t")
    print(" ")

Shell指令碼：

#!/bin/bash/
for((i=0;i<10;i++))
do
        for((j=1;j<=i;j++))
        do
                ((product=$i*$j))
                echo -ne $i*$j=$product" "
        done
        echo
done
exit

Scala語言:

for(i <- 1 to 9) {
  for(a <- 1 to (i)) {
    print(i + "*" +a + "=" + i*a + "\t" )
  }
  println(" ")
}
}
